LMV1032-06/LMV1032-15/LMV1032-25

Amplifiers for 3-Wire Analog Electret Microphones

General Description

The LMV1032s are an audio amplifier series for small form

factor electret microphones. They are 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 to

an electret microphones that incorporates an LMV1032 al-

lows for a dramatic reduction in supply current as compared

to the JFET equipped electret microphone. Microphone sup-

ply current is thus reduced to 60 µA, assuring longer battery

life. The LMV1032 series is guaranteed for supply voltages

from 1.7V to 5V, and has fixed voltage gains of 6 dB, 15 dB

and 25 dB.

The LMV1032 series offers low output impedance over the

voice bandwidth, excellent power supply rejection (PSRR),

and stability over temperature.

The devices are offered in space saving 4-bump ultra thin

micro SMD (TM) lead free packages and are thus ideally

suited for the form factor of miniature electret microphone

packages. These extremely miniature packages have the

Large Dome Bump (LDB) technology. This micro SMD tech-

nology is designed for microphone PCBs requiring 1 kg

adhesion criteria.
