illustrate
The LMV1012 is a small electret microphone audio amplifier family. This 2-wire combination is designed to replace the JFET amplifiers currently in use. The LMV1012 series is ideal for applications where high signal integrity is required in environments with RF noise, or in mobile communications. The LMV1012 audio amplifier is guaranteed to operate at 7.8 dB, 15.6 dB, 20.9 dB and 23.8 dB fixed gain over a 2.2V to 5.0V supply voltage range. These devices have excellent THD, gain accuracy, and temperature stability compared to JFET microphones.
The LMV1012 family implements a two-pin electret microphone solution that provides direct pin-to-pin compatibility with existing JFET markets.
These devices are available in extremely thin, space-saving 4-ball micro SMD packages. The LMV1012XP is designed for 1.0mm canisters and thicker ECMs. These extremely miniature packages are designed for condenser microphones (ECMs) form factor.
