ADAU1466 and I2C Operation
I need to use I2C to control an ADAU1466, rather than the serial SPI. I have used an eval board with its serial SPI interface to verify operation of my ADC and DAC circuits (I2S out and in to ADAU1466

How to load different end-user presets on a adau1701 without MCU
Hi, I'm using a ADAU1401/1701 DSP for some of our projects, but I want to be able to load completely different sigma studio project files, preferably with a dip switch, or with a single button that ro

Help with ADC noise in one channel please.
Hello, Setup: 2 channel ADC set up as master into ADAU1446, as slave. I'm having a slight problem in that I am getting full range noise (white noise/hiss) on one channel of my ADC, only when a signal

ADAU1446 errata, delay on SDATA_IN0 and one clocking question.
Dear AD support, we're in the middle of evaluating the ADAU1446 as a central part of a multi-DSP, multichannel audio solution. After initial tests with the official EVM, we're currently doing measurem

Can I run TDM16 at 96kHz?
I have done a few designs using ADAU1446 and ADAU1442 in which we run the chip from a 24.576 MHz crystal so I have done TDM8 interfaces at 96kHz without problems. Now I see from the data sheet that AD

Spikes on MPIO outputs
I designed and built a board using the ADAU1446. I have done several other projects with I2S, but this is my first time with a DSP. The ADAU1446 is connected via I2C to a Raspberry Pi. The DSP respond
