LMV1012, Pre-Amplified ICs for High Gain 2-Wire Microphones

The LMV1012 is an audio amplifier series for small form factor electret microphones.

This 2-wire portfolio is designed to replace the JFET amplifier currently being used.

The LMV1012 series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, suc
