The LMV1032-15 is an audio amplifier series for small form factor electret microphones. It is designed to replace the JFET preamp currently being used.
The LMV1032-15 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 LMV1032-15 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 LMV1032-15 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.
