App note: Pre-amplifying the analog output of a MEMS microphone

Designing pre-amp for MEMS microphone found in this app note from ST Microelectronics. Link here (PDF)

This application notes describes the key parameters related to pre-amplification of the output signal of an analog MEMS microphone (MP23AB02B). A solution is proposed based on the TS971 op amp. For a differential output configuration, we can consider using the TS472. The information in this document should allow you to design your own circuit suitable for your application.
