www.ti.com SNAS291B – MARCH 2005 – REVISED APRIL 2013 LMV1015 Analog Series: Built-in Gain IC's for High Sensitivity 2-Wire Microphones
Check for Samples: LMV1015 FEATURES DESCRIPTION The LMV1015 is an audio amplifier series for small
form factor electret microphones. This 2-wire portfolio
is designed to replace the JFET amplifier. The
LMV1015 series is ideally suited for applications
requiring high signal integrity in the presence of
ambient or RF noise, such as in cellular
communications. The LMV1015 audio amplifiers are
ensured to operate over a 2.2V to 5.0V supply
voltage range with fixed gains of 15.6 dB and 23.8
dB. The devices offer excellent THD, gain accuracy
and temperature stability as compared to a JFET
microphone. 1 2 (Typical LMV1015-15, 2.2V supply, RL = 2.2 kΩ,
