Part Number: TLV320AIC3256 Hi Team,
My customer is running into a problem where MIC_Detect fluctuates without unplugging the MIC when the ambient temperature changes from 25C to -40C and -40C to 25C( they said the problem is easily reproduced when they…
Part Number: TLV320AIC3256 Hello, As part of my design, we have 3 biquad filters where the coefficients were calculated based on a 32kHz sampling rate.
Is it possible that we could use the same filter coefficients if we cut the sample rate in…
Part Number: TLV320AIC3256 Hello,
I am currently working to implement AGC on a design using TLV320AIC3256 codec. In my PPS model, Currently I have used the default settings with the SW AGC block. I intend use the following values for my design
AGC enabled…
Part Number: TLV320AIC3256 Hello,
I am working on the following design where I have an analog mic and a digital mic interfaced to the codec. I am sampling both the mics at 32kHz. Currently I am making use of the LeftAGC registers to implement AGC for…

Dear TI teams,
For our customer's application: We use the MCU (STM32) and codec IC (TLV320AIC3256). We found the confuse about extra gain here.
We use the label mic, and its spec…

How to tune TLV320AIC3256’s Analog mic SW gain or EQ?
This is our testing result, the low frequency is too low. That low then 1KHZ.
Part Number: TLV320AIC3256 Hi,
We're trying to get the AIC3256 running in a new design and have an issue where it seems like the miniDSP's are not running.
Reading/writing over I2C to load the codec seems to be working fine.
VSYS, IOVDD = 3.01v…
Part Number: TLV320AIC3256 Other than a simple HPF, is there an algorithm available from TI (either in PurePath Studio or elsewhere) that can be implemented in the miniDSP to remove microphone wind noise from a 2-mic input configuration?
For example,…
Part Number: TLV320AIC3256 We are having difficulties in achieving unipolar configuration for headset connection and associated MICBIAS of 2.5V
Below are the configurations we have done to set the MICBIAS:

Hi,
I am using the Biquad Filter Design Tool in the PurePath Studio. I choosed the Equalizer(Q factor) filter. Then I set the Fc, Gain, Q as shown in Fig.1
Applying the equations in section 1.2 of Biquad Filters Application…
