LMV1012 is a small electret microphone audio amplifier series, which is mainly used to replace the widely used JFET amplifier. LMV1012 seriesareused for adapting to the environmental site or RF noise that requires signal integrity requirements for applications, such as cellular communications systems, PDA's, car accessories etc. It guarantees 2.2 ~ 5.0V operating voltage range, the fixed gain of 7.8dB, 15.6dB and 23.8dB. Relative to the JFET amplifier, LMV1012 series amplifier has excellent gain accuracy and temperature stability. LMV1012 series can be used for two foot small electret microphone, direct pin to pin compatible JFET microphone on the market today. The device provides two 4-bump micro SMDTM package, LMV1012TP-07、LMV1012TP-15、LMV1012TP-25 pot package 1.8mm thickness, LMV1012UP-25 pot package 1.3mm thickness. It is applicable to most small electret condenser microphone. The pinout of LMV1012 is shown as below. Internal circuit:
