This product from nihtila.com are using best quality preamplifier feeding the ADC. I will use it for ultrasonic echo analysis in short duration measurement using ESP32. It is the best deal today due to no restocking from AKM semiconductor since the end of 2019.
I received my AK5572 v1.2 , and I have to say that it is of exceptional quality. Not only the circuit board, hardware etc .. but also the sound quality is outstanding. It doesn’t have to hide behind other “high end” ADCs in any way, the opposite is the case.
