• ADAU1361 - inquiry about NOISE GATE FUNCTION


    I have a question about NOISE GATE FUNCTION threshold in ADAU1361.

    What is the input signal for the threshold tied to?

    I think input signal in datasheet means "input signal + gain boost " (not including PGA gain).

    (For example, mic signa…

  • ADAU1361/1761 device driver


    Customer is bringing up Audio Codec board with ADAU1361. They can access the codec with I2C interface and record/playback audio successfully. They are trying to port the codec on Linux OS but have some problems. 

     Do you know who owns the code/driver…

  • ADAU1361/ADAU1761 anti-alias

    We found that with the same configuration, a 48k sample rate, and an input signal greater than 24kHz, the adau1361 does not show a mixed signal, while the adau1761 does.

    Can you analyze the cause of this problem?

  • ADAU1361 LAUX and RAUX sampling


    Could you confirm if the LAUX And RAUX inputs can be simultaneously ADC processed as well as played through LHP and RHP ?

    If not, how much would be lag in between the input and output?

  • ADAU1452 serial data clocking for an ADAU1361 simultaneous playback and record

    I am considering a project that would use an ADAU1452 to receive serial audio samples from an ADAU1361, process them, and then send them back to the ADAU1361 for output. The ADAU1361 contains only a single set of BCLK / LRCLK pins, and thus operates fully…

  • Reading max-hold sample values from ADAU1542 to implement automatic ADAU1361 gain configuration

    My project (a fully-custom bass/guitar effects processor) consists of an ADAU1452 DSP, an ADAU1361 codec, and an STM32 microcontroller. Given the vast array of potential input signal levels (active vs passive pickups, direct input from the instrument or…

  • ADAU1361 DC Offset


    we have used the ADAU1361 in a product that will be operational this year and we are quite happy with the way it works. We are pairing it with a Linux box to capture analog audio and doing our captures using the ADI driver adjusted to run ou our…

  • Status of ADAU1361 when the headphone amplifier is not used


    I have a question about ADAU1361.

    Will it be Hi-Z when the headphone amplifier is not used in ADAU1361?

    I would appreciate it if you could reply.

    Best regards,


  • ADAU1361 ADC Full-Scale Level with negative PGA gain

    Hello Analog Community,

    The ADAU1361 datasheet states an ADC full-scale level of 1 Volts rms when operated with AVDD = 3.3 Volts. My question is, when using the PGA in single ended mode (line-in) with a gain of -6 dB, will the device accept 2 Volts rms…

  • ADAU1361 differential amplifier not working, no internal bias on input pins - damaged part, or just misconfigured?

    I'm bringing up a new design that utilizes an ADAU1361, and I've run into a bit of a snag that I'm hoping is just due to a misconfiguration of the device, but which I fear is actually evidence that the device itself is damaged (with everything being out…
