LMV1015 Datasheet (National Semiconductor)

LMV1015, Built-in Gain IC

The LMV1015 is an audio amplifier series for small form factor electret microphones.

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

The LMV1015 series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, such as in cellular comw
