• ADAU1772 ADC input saturation

    Hello!

    I'm using ADAU1772 to read 4 analog lines, controled by a Raspberry Pi. The core, PLL and PGAs are disabled. AVdd is 3,3 V and the AINRef inputs are tied to CM. 

    With a 1 kHz sine wave with 0,6 V of amplitude in the ADC input, I'm getting a clipped…

  • Testing ADAU1772 Serial I/O using APx555

    I have a loaner Audio Precision APx555 analyzer and would like to test the converters of the ADAU1772 using the Serial I/O.

    I am using the ADAU1772 eval board and am not able to get the Serial I/O on the analyzer set correctly to test the board.

    Is there…

  • Using ADAU1772 for microphone beamforming

    We used an ADAU1772 to create a simple microphone beamforming application, with two omnidirectional ADMP504 MEMS microphones mounted in an endfire configuration.

    While the ADAU1772 has no delay cells in its library, you can still create delay by using…

  • ADAU1772 12 channel

    Hello, we have an application where we need 12 channel ADC. We have a Microprocessor that can do 32Bit TDM 8 (256BCK per frame).4

    Is there a way I can combine 3 ADAU1772 (we are hoping to use this part since we are already using it in other products…

  • ADAU1772 - Output Noise level in balanced vs Single-ended

    Hi,

    I am using the ADAU1772 codec to drive  low impedance headphones (8 Ohms) for ANC and therefore I need an external amplifier between the codec and my headphones.

    This additional gain raises the noise floor too much so I try to use differential output…

    Hello, we have an application where we need 12 channel ADC. We have a Microprocessor that can do 32Bit TDM 8 (256BCK per frame).4

    Is there a way I can combine 3 ADAU1772 (we are hoping to use this part since we are already using it in other products) to…

  • RE: Noise Cancelling on ADAU1772 Eval Board

    Hello Nicorates

    To tune phase more precisely, you can use filters like peak filter, low & high pass filter etc... To see the effects of the filter, use stimulus and probe to see gain and phase plot. Make sure you filter out your signal after 1kHz with…

  • latency in ADAU1772

    Hello, i'm using AUAU1772 in my ANC project.

    To measure system internal latency, i wrote a program in host(TI-C6748,McASP interface) which generate a digital sine signal and transfer it to 1772 using I2S, then 1772 transform it to analog form and…
