Datasheet
The LMV1032-06/LMV1032-15/LMV1032-25 are audio amplifiers 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 blue- tooth 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 cur- rent is thus reduced to 60 µA, assuring longer battery life.

LMV1032 is an audio amplifier series designed for small form factor electret microphones. It is intended to replace the JFET preamp currently used. The LMV1032 series is ideal for applications requiring extended battery life, such as a Bluetooth communication link. The addition of a third pin in electret microphones incorporating the LMV1032 allows for a significant reduction in supply current compared to JFET-equipped electret microphones, reducing microphone supply current to 60µA, ensuring longer battery life. The LMV1032 series is guaranteed for supply voltages from 1.7V to 5V and has fixed voltage gains of 6dB, 15dB, and 25dB. The LMV1032 series offers low output impedance over the voice bandwidth, excellent power supply rejection (PSRR), and temperature stability. The devices are offered in a space-saving 4-bump ultra-thin micro SMD lead-free package, making them ideally suited for the form factor of miniature electret microphone packages.
