The LMV1012 is an audio amplifier series for small form factor electret microphones. It 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 guaranteed to operate over a 2.2V to 5.0V supply voltage range with fixed gains of 7.8dB, 15.6dB and 23.8dB. The devices offer excellent gain accuracy and temperature stability as compared to a JFET microphone.
