Hi Guy
It seemed that you had submitted the two same questions via e2e. I have answered you in another thread( TLV320ADC5140: Ti pcmdevice-core.c does not compiles with kernel-5.10.158 - Audio forum - Audio - TI E2E support forums ). Let me know whether…
Part Number: TLV320ADC5140 The customer is using TLV320ADC5140 to sample four analog microphone signals.
Because the I2S host is a standard I2S and cannot be modified, only tlv320adc5140 can be connected to the standard I2S interface.
Whether it is available…
Hi Guy
We weeks ago, I suggested you using this code. lpaa-android-drivers/pcmdevice-linux-driver - Unnamed repository; edit this file 'description' to name the repository.
Here is the example to how to integrate the pcmdevice driver and set the…
Sample code for volume kcontrol is in the following patches, kindly focus on adc5120_analog_gain_ctl and adc5120_digi_gain_ctl in v9-0001, study how they are referenced.

Hi Daveon,
We finally could test the TLV320ADC5140 at 96kHz sampling rate. I can confirm that at 96kHz we do have 2 BiQuad filters available per channel.
So the application note ( https://www.ti.com/lit/an/sbaa381a/sbaa381a.pdf?ts=1707467053335&ref_url…
Hi Sanjay,
Customer don't use MicBias. Should it be open or connected to ground via caps?
Sanjay Dixit said: through the centre of the IC
Does it mean Themal Pad (VSS)?
When the DGND and AGND are separated as shown in the figure below, should…

Hi,
we are evaluating the TLV320ADC5140 on a custom PCB to sample analog MEMS with 4 channels at FS 192 kHz sampling frequency and bitclock BCLK 24.6 MHz.
The configuration is the base one from the datasheet with auto PLL setting…
Part Number: TLV320ADC5140 Hi
My customer care about data sampling time of TLV320ADC5140. So l would like to know what is t he delay time range of audio data from input pin to output pin?
Thanks.

Part Number: TLV320ADC5140 Hi, Team
our customer use ADC5140 in their pro audio speaker, and they use DC-coupled for input signal.
and they prefer to adjust the input impedance to improve the system performance. they find 2.5 kΩ should be a good input impedance…
