TLV320AIC3107: AGND/DGND implementation in a single-GND system

user1238011 — Mon, 25 May 2026 02:45:36 GMT

Part Number: TLV320AIC3107

Hi,

The application where we plan to add this IC uses a single power supply and a single GND system for both analog and digital circuits.

However, on the evaluation board for this IC, AGND and DGND are connected through a resistor, and each uses a separate GND plane.

In the existing application, separating the GNDs or power supplies would significantly affect many surrounding circuits, so separation is not practical.
Also, the current design already satisfies the required audio performance.

The GND philosophy of this application is to use a 10-layer PCB with one large common GND plane, and to place GND layers adjacent to the signal layers in order to improve stability against GND potential fluctuation.

In this case, the added IC will only use LINE1LP and LEFT_LOP.
Other functions such as the speaker output will not be used.
Therefore, large analog currents are not expected to flow.

Under these conditions, would you still recommend separating DGND and AGND for this IC only?

If AGND is separated, the AGND plane would become very small, and I am concerned that the GND impedance and stability may actually become worse.

Kind regards

TAS3251: TAS3251 DSP

Mohammad Naghizadeh — Thu, 21 May 2026 09:45:52 GMT

Part Number: TAS3251

i have a question and i will be grateful if you can help me.
main project: connecting STM32H743 to TAS3251 and playing an mp3 file saved on a usb flash which is connected to stm32.
problem: cant get dsp to work. (tas3251 plays the song also i can change its volume by 0x3d and 0x3e but i cant get the dsp to work)

what i have done up to now:
i decode the mp3 file on the usb flash connected to stm32. i connect the i2s pins of stm32 to the ta3251 (4 wires- i also generate the MCLK) and i play the music successfully. also i can change the volume by varying the number written for 0x3d and 0x3e. i send you the TAS3251_init function which i wrote up to now:

void TAS3251_LoadRegisters(const cfg_reg *r, uint16_t size)
{
for(uint16_t i=0;i<size;i++)
{
HAL_I2C_Mem_Write(&hi2c3,TAS_ADDR,r[i].reg,I2C_MEMADD_SIZE_8BIT,(uint8_t*)&r[i].val,1,HAL_MAX_DELAY);
HAL_Delay(1);
}
}

cfg_reg registers[] = {
//program memory
{ 0x00, 0x00 },
{ 0x7f, 0x00 },
{ 0x02, 0x11 }, //PowerDown DSP. Bit 0 not documented
{ 0x01, 0x11 }, //Reset module & registers. Bits are auto cleared
{ 0x00, 0x00 }, //Wait

{ 0x7f, 0x00 },
{ 0x00, 0x01 },
{ 0x02, 0x00 },

//Unmute the device
{ 0x00, 0x00 },
{ 0x7f, 0x00 },
{ 0x03, 0x00 },
{ 0x2a, 0x11 },

};

my problem starts from here. i want to start dsp and change the volume by the value written for 0x44 and 0x48 register which are on page 0x8c .
when i change the value of 0x44 and 0x48 nothing happens (the volume doesn't change) for example when i change it to 0 i expect the sound to be muted but it doesn't happen.
i send you the second init function which i wrote to get the dsp to work:

{ 0x28, 0x00 }, //I2S config
{ 0x29, 0x01 },

{ 0x02, 0x00 }, //Wake up DSP

//Sample rate update

TAS2563: How to switch profiles without using tinymix

Hitoki Ishikawa — Thu, 21 May 2026 01:58:36 GMT

Part Number: TAS2563

Hi,

I previously received the TAS2563 driver from you in the following thread:
URL:TAS2563: TAS2563 Linux driver request for Kernel 6.1 and RCA file generation tool

Could you please advise how to switch profiles using this driver?
The user guide states that profiles can be switched using the following command:

tinymix "TASDEVICE Profile id" 0

However, we would like to know how to switch profiles without using the shell.
Is there a function in the driver for switching profiles?

Best regards,

PCMD3140-Q1: Power Dissipation Calculation

Amirthathaarani S — Wed, 20 May 2026 17:20:11 GMT

Part Number: PCMD3140-Q1

Hi Team,

I am estimating the power dissipation of the PCMD3140-Q1 device for thermal analysis for heatsink design.

Using the datasheet current values, I calculated the IC power dissipation as:

PD=(VAVDD×IAVDD)+(VIOVDD×IIOVDD)

For my case:

VAVDD=1.8V
IAVDD=8.1mA
VIOVDD=1.8V
IIOVDD=0.05mA

Calculation:

PD=(1.8×8.1mA)+(1.8×0.05mA)=14.7mW

So the estimated device power dissipation is approximately 14.7 mW.

Could you please confirm whether this approach is correct for estimating the IC power dissipation of PCMD3140-Q1?

Thanks.

TLV320ADC5140: Development started guide

David Eaton — Wed, 20 May 2026 09:38:08 GMT

Part Number: TLV320ADC5140

Hi Help team,

I wondered if there was a guide and/or a recommended development system to testout the features of the ADC5140EVEM-PDK. I am aware of a GUI for this device but I need to create my own interface to the chip so that I can adjust all parameters available on the device. SO I will need a complete development environment for this hardware.

TPA3255: Test conditions of 315 W/ohm maximum output mentioned in TPA3255 datasheet

quan wu — Wed, 20 May 2026 07:58:25 GMT

Part Number: TPA3255

Dear Support Teams:

We designed a 300W*2 BTL output power amplifier with TPA3255. When testing the output power, we found that the efficiency was very poor when testing with a 4ohm pure resistance load. When the output power was 250W per channel, the AC input power of the power supply was close to 750W, and the product would be protected in about 3 seconds. If the 300W per channel was tested with a 4ohm load with inductive reactance (about 70uH), The input power of AC terminal is about 615W, and the burning time can last for about 2 minutes. I would like to ask whether the load used by TI DEMO board when testing 4ohm 315 W * 2 output is pure resistance or inductive. Are there any test pictures or videos?

AM625: Running MCASP as master with external AUDIO_EXT_REFCLK

LocoField Ko — Wed, 20 May 2026 00:55:18 GMT

Part Number: AM625

About two months ago, I successfully played 4-channel audio using McASP on the BeagleBone Black (AM335x). However, since the BeagleBone is an older platform, I am now trying to implement the same functionality on the PocketBeagle2 (AM6254) for a more modern and lower-cost system.

One thing I noticed is that, unlike the BeagleBone Black, the PocketBeagle2 does not appear to have an onboard audio X-TAL (24.576MHz), so it seems that the audio clock must be generated differently.

I was able to get audio playback working, but the playback speed is completely incorrect — the audio finishes within about 1 second, which makes me suspect that McASP is running from an incorrect AUX clock source or an unintended clock configuration. (when I explicitly set the clock inside simple-audio-card,cpu, so I kept only sound-dai=<&mcasp0>;)

This thread was extremely helpful:
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1487650/am625-running-mcasp-as-master-with-external-audio_ext_refclk-of-24-576mhz

https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/am62x/clocks.html#clocks-for-mcasp0-device

However, even after checking the clock summary and trying several debugging approaches, it still seems like my clock configuration is not being applied correctly.

I would appreciate any advice on the proper way to configure the McASP audio clocks on AM6254 when running McASP as master.

TAS2572EVM: Speaker caused desense

ba wanqin — Tue, 19 May 2026 05:31:44 GMT

Part Number: TAS2572EVM
Other Parts Discussed in Thread: TAS2572

We have done quite some measurements on multiple units to confirm this is speaker caused desense.

1 The desense is only on when speaker is on. The desense is off when we stress other subsystems.

2 The desense will go up if we use larger sound level.

There are some data difference between US lab and China factory labs due to different setups.

But the above conclusions are very sure.

Can you provide commands to change switch frequency? Why it’s taking such long time?

TAS2505: Low Audio output with TAS20505 Digital input Speaker Amplifier

Subramanian Gurusamy — Tue, 19 May 2026 05:27:12 GMT

Part Number: TAS2505

Low Audio output with TAS20505 Digital input Speaker Amplifier
We are using TAS20505 Digital input Speaker Amplifier with i.MX8 MP Processor on I2S Bus to facilitate
Audio alarm for the user.We are using Kernel 5.10 Yocto build and added driver from below repository.
https://git.ti.com/cgit/lpaa-android-drivers/tas2505-linux-driver/

We added required client node details in DTS File. We tested the sound with 2W/4Ohms speaker with aplay. And we observed that the volume level is very low.We also adjusted DAC, Speaker Amplifier and driver volume with amixer command.

Thanks,
Subramanian G

TAS5558: TAS5558 change to TAS5538

Kevin Huang8 — Tue, 19 May 2026 04:12:57 GMT

Part Number: TAS5558
Other Parts Discussed in Thread: TAS5538

If the TAS5558 is replaced with the TAS5538, do the internal rigster settings need to be modified? Does the GUI same as the TAS5558?

TAD5212: output short circuit detection

John Wehle — Tue, 19 May 2026 03:35:43 GMT

Part Number: TAD5212
Other Parts Discussed in Thread: TMUX2889,

Is there an application note describing the short circuit detection?

The situation of interest is a stereo singled-ended capacitor (270uF) coupled output connected through a TMUX2889 to a headphone TRS jack. If a mono headphone is inserted will that trigger a output short circuit interrupt (due to ring being shorted with sleeve) with the details in OUT_CH1_LTCH at which point the MCU can reconfigure the TAD5212 for mono operation?

The OUT_CH1_LTCH register description says it's for DC fault diagnostics and I didn't seen any discussion of how the short circuit detection works so it's not clear to me if can be used to distinguish between a mono and a stereo headphone when capacitor coupling is being used.

Hi,

Please check our schematic and waveform for TPA2011, the chip unable to start and we have no idea the error for our design, thanks.

The yellow is the EN pin, and the green is the audio signal:

TAC5301-Q1: Linux driver for TAC5301QRGERQ1

Andrea Nicoletti — Mon, 18 May 2026 14:42:18 GMT

Part Number: TAC5301-Q1

Hello,

We’re looking for linux drivers for TAC5301QRGERQ1 for linux version 6.18.y. I found another forum post with a similar part number but the link to the drivers is broken. Looking into GitHub I found a Linux kernel provided by TI with codec file tac5x1x.h but I am not sure is compatible with my part number.

bìBest Regards
