Part Number: TLV320AIC3268 I have 4 analog mics connected to the TLV320AIC3268. They are mixed at the MicPGA and routed into the ADC.
On the output, the DAC outputs to the Headphone output. Decent output but a fair amount of noise.. Not so good.
When…
Hi Jeff,
Can you help me by providing detail procedure to enable adaptive filtering in TLV320AIC3254 and TLV320AIC3268 and please confirm is there any chance to achieve limited noise cancellation, if I enable this feature.
Thanks & Regards,

Part Number: TLV320AIC3268 Dear TI Engineers,
I have created new coefficients for a BiQuad (Low Freq Bandpass). This consists of 5 coefficients with each coefficient taking up 4 bytes in length. As you can see from image below, PPS tells us where to place…
Part Number: TLV320AIC3268 Is there a way to increase gain on the I2S port? I only know of increasing the DAC digital volume control but that creates more problems on the downstream analog outputs.
Part Number: TLV320AIC3268 The aic3268 datasheet page 38 notes:
When the charge pump circuit is disabled, VNEG acts as a ground terminal, allowing unipolar configuration of the headphone amps. However there is no diagram showing the connections for a…
Part Number: TLV320AIC3268 Dear TI Professional,
(1) Can you provide me any link to documentation on calculating and uploading DRC/DRC2 coefficients?
(2) PPS provides an address where the coefficients are supposed to be loaded but can you provide information…
Part Number: TLV320AIC3268 Dear E2E,
Can you look at these two threads? I really could use the help getting past these two problems:

Part Number: TLV320AIC3268 Is there a reference document that explains clocking for these TLV320 DSPs?
For example, if my desired sample frequency is 48KHz, and I choose to use my own clock. I assume the MCLK is best at some integer multiplier of the…
Part Number: TLV320AIC3268 Using PurePath Studio I created a configuration that includes two instances of a BiQuad. One is a High Bandpass Filter and the second is a Low Bandpass Filter. A right click on the BiQuad object presents a menu with Help. Help…
Part Number: TLV320AIC3268 Dear TI Professional,
Okay. I now have my coefficients and they are looking pretty good. Now, it is time to do the upload. I have been reading the document, SLAA447, and this has been very helpful. When using PPS, it tells me…
