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.
The LMV1015 series enables a two-pin electret
microphone solution, which provides direct pin-to-pin
compatibility with the existing older JFET market.
Texas Instruments' built-in gain families are offered in extremely thin space saving 4-bump DSBGA
packages (0.3 mm maximum). The LMV1015XR is
designed for 1.0 mm ECM canisters and thicker.
These extremely miniature packages have the Large
Dome Bump (LDB) technology. This DSBGA technology is designed for microphone PCBs
requiring 1 kg adhesion criteria.
