ADAU1772 IC 2-WinE2PromLoader Creates 16KB File
The WinE2PromLoader tool does not auto-configure itself to the EEPROM you are using or the necessary minimum file size. The appropriate filesize is 4KB. I can go into the register control section, con

ADAU1452 at 96kHz into ADAU1787 at 768kHz via I2S
Hi All, I am working on a project where I need to run a ADAU1452 with external ADC's and DAC's at 96kHz samplerate. The ADAU1787 get its signal from the ADAU1452 via I2S at 96kHz samplerate interpolat

ADAU1452 and ADAT Lightpipe
Hello, we need a device to convert 8-channel LPCM with 16/24-bit@32/44.1/48/88.2/96/176.4/192kHz (4x I2S) to ADAT Lightpipe 24-bit@48kHz. Is there some kind of driver IC which can convert the serial o

How to transmit/receive SPDIF user data reliably?
For a stereo active speaker system, we need to send the same SPDIF audio and control information to ADAU1467 devices in both speakers. The approach is to make one speaker a "primary" that receives the

ADAU1772 - any way to create an oscillator in the core?
I was asked if there was any way we could create an oscillator in the DSP core to try and debug our glitch issue. I don't see anything unless I were to try to use a filter with 100% feedback... hardwa

ADAU1467, Sigma Studio v4.7 different Level detectors show different signal levels
I am currently testing a custom board using ADAU1467 and ADAU1361. Currently I want to verify that the DAC of ADAU1361 behaves as expected. Therefor I create a test tone (sine 1kHz, 0dB) with ADAU1467
