The LMV1012 is an audio amplifier series for small form factor electret microphones. This
2-wire portfolio is designed to replace the JFET amplifier currently being used. The LMV1012 series
is ideally suited for applications requiring high signal integrity in the presence of ambient or RF
noise, such as in cellular communications. The LMV1012 audio amplifiers are specified to operate
over a 2.2V to 5.0V supply voltage range with fixed gains of 7.8 dB, 15.6 dB, 20.9 dB, and 23.8 dB.
The devices offer excellent THD, gain accuracy and temperature stability as compared to a JFET
The LMV1012 series enables a two-pin electret microphone solution, which provides direct
pin-to-pin compatibility with the existing JFET market.
The devices are offered in extremely thin space saving 4-bump DSBGA packages. The
LMV1012XP is designed for 1.0 mm canisters and thicker ECM canisters. These extremely miniature
packages are designed for electret condenser microphones (ECM) form factor.
