Differential mode input path
Pls send me the path for Differential input to ADAU1761. Will giving input to LINP and LINN is sufficient or do I need to use both left and right channel? Screenshot is attached. Pls reply quickly. Au

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 th

ADAU1761 MIC input single Ended Or Differential?
I am confused a bit about the inputs to the PGA. (Figure 33. Stereo Differential Microphone Configuration) ADAU1761 pdf, shows one side of the MIC grounded at the input of the circuit. Seems that just

An Integrator Block for SigmaDSP
Looking at GTG737's implementation of an adaptive mixer -- and GatsbyDSP's comment that it would run away with itself -- gave me the idea to build an integrator, something that several folks have aske

Dual Inline Microphone Noise Cancelling
I would like to mimic a noise cancelling differential microphone using two omni-directional microphones that are oriented in-line with the audio path. An example of this would be your bluetooth headse

Creating a differential output using a SigmaDSP with single-ended DACs
I was recently asked how to create a differential output using the single-ended DACs on the ADAU1701. It is easy to do this in SigmaStudio by making a copy of the output signal and simply inverting it

need to use the bias voltage for the differential inputs adau1761?
I am designing a mic mixer project that will be connected to the output from a wireless recieved (balanced xlr). do i need the circuitry used o the evaluation board, and do i need to use the BIAS volt

ADAU1761 LD/RDVOL ignored
Hi, I'm using the two differential inputs of the ADAU1761 and I'd like to set the input volume. The ALC is set to OFF for both channels. I get the input from the differential pair, but the RDVOL and L
