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).
