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 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.
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 package and are thus ideally
suited for the form factor of miniature electret microphone
packages.
