The task is to write sound from an analog microphone via I2S to the raspberry Pi 3. I2S, because. all other interface pins are already taken. Please advise a board like ADS1115, only with a higher sample rate. (ADS1115 has only 860). Rays of goodness for links to aliexpress.

Texas Instruments has quite a few audio ADCs with I2S. See for example pcm1808. There are on Ali in the form of ready-made modules.
