32 channel DAC @ 192kHz for testing: Recommendations?
For some experiments, we'd like a 32-channel DAC @ 192kHz. This is just for lab use so cost isn't a big factor. I was hoping to find some combination of eval boards to do this with relative ease. Ther

Single Level Detector in ADAU1452
Hi, I use Single Level Detector to read level in my program. I find that the data from 1452 is 4 bytes which doesn't contain the sign bit, so I think it's not 8.24 format. I have the following questio

ADAU1452+2xAD1933 multichannel output
Good day. I needed to get 16 channels of audio output from one source. I plan to use ADAU1452 and two AD1933 chips for this. In the datasheet on ADAU1452 I found a "Flexible TDM Otput" section. Can yo

ADAU1966
Hi, We are trying to use this DAC to generate constant voltages to control some test equipment (so not fast changing audio, DAC was chosen by our customer). This is having to be driven by a PIC32MX in
