Preliminary
ANALOG SERIES:
PRE-AMPLIFIED IC'S FOR
HIGH GAIN 2-WIRE
MICROPHONES
 DESCRIPTION
The UTC ULV1012 is high gain, high impedance per-amplifier
which is designed to replace the JFET amplifier currently being
used. The UTC ULV1012 audio amplifiers are specified to operate
over a 2.2V to 5.0V supply voltage range with fixed gains of 7.8dB,
15.6dB, 20.9dB, and 23.8dB. The devices offer excellent THD, gain
accuracy and temperature stability as compared to a JFET
microphone.
The UTC ULV1012 series is ideally suited for applications
requiring high signal integrity in the presence of ambient or RF
noise, such as in cellular communications.
The UTC ULV1012 suited for use in headsets, mobile
communications, automotive accessories, PDAs, accessory
microphone products and telephone Electret Condenser
Microphones (ECM).
