LMV1091: Need SMD microphone suggestion for LMV1091

Part Number: LMV1091

Hello Team,

I am trying to make audio circuit and for that I am planning to use LMV1091.

I am looking for "SMD" Microphone suggestion  compatible with LMV1091. If possible also suggest related circuit.

Thanks

Sudhanshu

    Hi, Sudhanshu,

    Welcome to E2E and thank you for your interest in our products!

    The related circuit would be the same for all the differential microphones. Basically, the LMV1091 would need of DC-blocking capacitors at the MIC inputs and some resistors to MICBIAS and GND as shown in the picture below. The resistors can go from 1Kohm to 2.2Kohm. In case of the blocking capacitors, they can go from 0.1uF to 0.47uF.

    Unfortunately, we are not able to suggest microphones in this case. However, if you have options for omnidirectional microphones, you may share the datasheet in order to see if it will work with the LMV1091 connections.

    I hope this helps you. Please let me know if you have additional questions or comments on this.

    Best regards,
    Luis Fernando Rodríguez S.
