LMV1012 Datasheet Pre-amplified Ics For High Gain 2-wire Microphones

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMV1012 Analog Series Pre-Amplified IC’s for High Gain 2-Wire Microphones August 2004 LMV1012 Analog Series: Pre-Amplified IC’s for High Gain 2-Wire.

General Description

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, such as in cellular munications.
