LMV1012 Analog Series: Pre-Amplified IC’s for High Gain 2-Wire Microphones
General Description
The LMV1012 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 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.
