I have a question ADAU7002.
Please tell me how you are doing downsampling when PDM → PCM conversion ADAU7002 inside.(Thin out data? Low pass filter? Etc.)
It uses rather standard methods of decimation from a 1-bit high sampling rate to a 20 bit result at the output sampling rate. So yes, it is a low pass filter.
Let me know if you need further information.
Thank you for your answer.
