The LMV1012 is an audio amplifier series for small form factor electret microphones. This series is designed for applications requiring high signal integrity in the presence of ambient or RF noise, such as cellular communications. The LMV1012 audio amplifiers operate over a 2.2V to 5.0V supply voltage range with fixed gains and offer excellent THD, gain accuracy, and temperature stability compared to JFET microphones. The LMV1012 series enables a two-pin electret microphone solution, providing compatibility with the existing JFET market. It is offered in extremely thin 4-bump micro SMD packages suitable for electret condenser microphones (ECM).
The LMV1012 Analog Series consists of audio amplifiers designed for small form factor electret microphones. These devices are intended to replace JFET amplifiers and are suitable for applications requiring high signal integrity in the presence of ambient or RF noise, such as cellular communications. The series offers fixed voltage gains of 7.8 dB, 15.6 dB, 20.9 dB, and 23.8 dB.
