LMV1012: replacement to MAX4063A

Patrick Chen(TPE System & Application)

Part Number: LMV1012

Hi Sir,

My customer is currently using MAX4063A, we would like to replace it and found that LMV1012 looks similar to it. But I am not familiar with Microphone Preamplifier, could you help check if we have a good solution to replace it?

Many thanks,

Patrick

Hi Patrick,

Do you have a data sheet of the competitor device?

LMV1012 is the kind of pre-amp that is used inside of the electret case. Is that what customer is looking for?

Patrick,

If customer only needs the microphone amplifier portion, then LMV1012 should be OK. There are several op-amps available as well if the package is too small to handle.

Unfortunately there is no direct part-to-part replacement for the mentioned device.
