LMV1032-06 - Amplifiers for 3 Wire Analog Electret Microphones

Datasheet Summary

Description

The LMV1032 is an audio amplifier series for small form factor electret microphones.

It is designed to replace the JFET preamp currently being used.

The LMV1032 series is ideal for extended battery life applications, such as a bluetooth communication link.

LMV1032-06/LMV1032-15/LMV1032-25 Amplifiers for 3 Wire Analog Electret Microphones February 2004 LMV1032-06/LMV1032-15/LMV1032-25 Amplifiers for 3 Wire Analog Electret Microphones General Description The LMV1032 is an audio amplifier series for small form factor electret microphones. It is designed to replace the JFET preamp currently being used. The LMV1032 series is ideal for extended battery life applications, such as a bluetooth communication link. The addition of a third pin in electret microphones that incorporate the LMV1032 allows for a dramatic reduction in supply current as compared to the JFET equipped electret microphone. Microphone supply current is thus reduced to 60 µA, assuring longer battery life. The LMV1032 series is guaranteed for supply voltages from 1.
