The LMV1012 is an audio amplifier series for small formfactor electret microphones. This 2-wire portfolio is designedto replace the JFET amplifier currently being used. TheLMV1012 series is ideally suited for applications requiringhigh signal integrity in the presence of ambient or RF noise,such as in cellular communications. The LMV1012 audioamplifiers are guaranteed to operate over a 2.2V to 5.0Vsupply voltage range with fixed gains of 7.8 dB, 15.6 dB,20.9 dB, and 23.8 dB. The devices offer excellent THD, gainaccuracy and temperature stability as compared to a JFETmicrophone.
