Analog Pre-Amplified IC's for High Gain Microphones
LMV1012 Analog Series:
Pre-Amplified IC’s for High Gain 2-Wire Microphones
General Description
The LMV1012isan audio amplifier seriesfor small form
factor electret microphones. This 2-wire portfoliois designed replace the JFET amplifier currently being used. The
LMV1012 seriesis ideally suitedfor applications requiring
high signal integrityinthe presenceof ambientorRF noise,
suchasin cellular communications. The LMV1012 audio
amplifiers are guaranteedto operate overa 2.2Vto 5.0V
supply voltage range with fixed gainsof 7.8 dB, 15.6 dB,
20.9 dB, and 23.8 dB. The devices offer excellent THD, gain
accuracy and temperature stabilityas comparedtoa JFET
microphone.
The LMV1012 series enablesa two-pin electret microphone
solution, which provides direct pin-to-pin compatibility with
the existing JFET market.
The devices are offeredin extremely thin space saving
4-bump micro SMD packages. The LMV1012XPis designed
for 1.0 mm canisters and thicker ECM canisters. These
extremely miniature packages are designedfor electret con-
denser microphones (ECM) form factor.
