TDM2 oder 8 channels
Hey together, one question. We know that it is possible to send 16 channels of audio via serial port 0/1 via a single SDATA pin (16 channels), via 2 SDATA pins (2x8channels) and 4 SDATA pins (4x4chann

ADAU1452 – Ripple/distortion occurs at low signal levels when using the xover filter.
The signal is distorted, similar to the blue response curve, when the volume is low using the General (2nd-Order / Lookup) filter on the ADAU1452. With other filters, this issue does not occur. I also

PLL_CTRL0 editing should happen before PLL_ENABLE changes from 0 to 1, but sigmastudio generates code where PLL_CTRL0 is edited after PLL_ENABLE is changed from 0 to 1
Hello We have a project utilizing the ADAU1462 and have noticed the file generation for the function "default_download_xx" where xx depends on the project name, might be wrong according to what is spe

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
