I recently did some ADC measurements in preparation for an update to my Audio VNA.? I mention it here as I think it has some stuff of interest to the T41 project.? The measurements are on-going, but as of now included the SGTL5000 (ADC side)and the PCM1808.? I believe it was the T41 use of the PCM1808 that got me to look at that part---thanks.? The web page for the study is

For this group, one interesting element that came out is that the PCM1808 produces 24-bit output data, but this is lost back to 16 if you input I2S via the Teensy AudioInputI2S followed by a Q15 to F32 conversion.? If you do the input via AudioInputI2S_F32 of the , it will include all 24-bits automatically, as well as saving a conversion.
