U4083B

Low-Power Audio Amplifier for Telephone Applications

Description

The integrated circuit, U4083B, is a low power audio The U4083B has an open loop gain of 80 dB whereas the

amplifier for a telephone loudspeaker. It has differential closed loop gain is adjusted with two external resistors. A

speaker outputs to maximize the output swing at low chip disable pin permits powering down and/or muting

supply voltages. There is no need for coupler capacitors. the input signal.

Features

Wide operating voltage range: 2 to 16 V

Output Power, P = 250 mW @ R = 32 (speaker)

o L

Low harmonic distortion (0.5% typical)

Wide range gain adjustable: 0 dB to 46 dB

Battery powered application due to low quiescent

supply current: 2.7 mA typical

Chip disable input to power down the integrated

circuit

Benefits

Low power down quiescent current

Drives a wide range of speaker loads

Low number of external components

Low current consumption
