Controlling DS1881 Digital Potentiometer from ADAU1463 for Analog Audio Volume (No External MCU)
Hi everyone, I'm working on a prototype board that uses the ADAU1463 DSP, and I’m experimenting with controlling the volume of an analog-only audio path (i.e., the signal does not enter the ADAU1463).

ADAU1787 serial port latency
Hi All, A project I'm starting on soon ideally would have lower noise and distortion figures than what the on board ADC's and DAC's of the ADAU1787 can do. Is the latency through the serial ports and

Master control port registers for address width and value?
Is it possible to set the SPI address width using the DSP control registers? I'm asking about the 2-byte (16-bit) versus 3-byte (24-bit) address variations. On a similar note, is it possible to set th

What is SPI mode CPOL CPHA for ADAU1701?
There seems to be quite a bit of confusion over ADAU1701 and SPI mode. What is it?! This post seems to indicate it's SPI mode 0 (CPOL=0 CPHA=0), RE: ADAU1701 SPI mode This says (not specifically about
