FEATURES  
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  
specified 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.

LMV1012-07: 7.8 dB  
LMV1012-15: 15.6 dB  
LMV1012-20: 20.9 dB  
LMV1012-25: 23.8 dB  
The LMV1012 series enables a two-pin electret  
microphone solution, which provides direct pin-to-pin  
compatibility with the existing JFET market.  
The devices are offered in extremely thin space  
saving 4-bump DSBGA packages. The LMV1012XP  
is designed for 1.0 mm canisters and thicker ECM  
canisters. These extremely miniature packages are  
designed for electret condenser microphones (ECM)  
form factor.
