The LMV1012UPX-20/NOPB 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 LMV1012UPX-20/NOPB series is ideally suited for applications requiring high signal integrity in the presence of ambient or RF noise, such as in cellular communications. The LMV1012UPX-20/NOPB 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 microphone.
The LMV1012UPX-20/NOPB 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.
