  • TLV320AIC3256: ADC Data Out?

    TI Thinks Resolved
    Part Number: TLV320AIC3256 I am working with the TLV320AIC3256 both on the evaluation board and on a custom board. We are able to play audio (in both implementations) through the I2S interface, through the headphone and line out ports with no problem…

  • RE: TLV320AIC3256: TLV320AIC326 Temperature change causing MIC_detect issue.

    HI, Good to know. Just DVDD and AVDD. Regards.

  • TLV320AIC3256: Biquad filter coefficients (derived from sampling rate A) for a different sampling rate B

    TI Thinks Resolved
    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…

  • TLV320AIC3256: TLV320AIC3256 PPS SW AGC

    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…

  • TLV320AIC3256: Switching between ADC processing blocks on the TLV320AIC3256

    TI Thinks Resolved
    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…

  • TLV320AIC3256: AMIC gain setting

    Other Parts Discussed in Thread: TLV320AIC3256 art Number: TLV320AIC3256 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…

  • TLV320AIC3256: How to tune TLV320AIC3256’s Analog mic SW gain or EQ?

    TI Thinks Resolved
    Part Number: TLV320AIC3256 hi TI 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.

  • TLV320AIC3256: miniDSP's not running?

    Resolved
    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…

  • TLV320AIC3256: Wind Noise Suppression Algorithm?

    Resolved
    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,…
