LMV1012 Analog Series:  
Pre-Amplified IC’s for High Gain 2-Wire Microphones  
General Description  
Features  
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 7.8 dB, 15.6 dB,  
20.9 dB, and 23.8 dB. The devices offer excellent THD, gain  
accuracy and temperature stability as compared to a JFET  
microphone.  
(Typical LMV1012-15, 2.2V supply, RL = 2.2 k, C = 2.2 µF,  
VIN = 18 mVPP, unless otherwise specified)

The LMV1012 series enables a two-pin electret microphone  
solution, which provides direct pin-to-pin compatibility with  
the existing JFET market.  
23.8 dB  
−40˚C to 85˚C  
The devices are offered in extremely thin space saving  
4-bump micro SMD packages. The LMV1012XP is designed  
for 1.0 mm canisters and thicker ECM canisters. These  
extremely miniature packages are designed for electret con-  
denser microphones (ECM) form factor.  
Applications  
n Cellular phones  
n Headsets  
n Mobile communications  
n Automotive accessories  
n PDAs  
n Accessory microphone products
