Conclusion

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. You can find the best-adapted MEMS microphone and op amp

from STMicroelectronics.
