Low-Power Audio Amplifier for Telephone Applications
Description
The integrated circuit, U4083B, is a low power audio
amplifier for a telephone loudspeaker. It has differential
speaker outputs to maximize the output swing at low
supply voltages. There is no need for coupler capacitors.
The U4083B has an open loop gain of 80 dB whereas the
closed loop gain is adjusted with two external resistors. A
chip disable pin permits powering down and/or muting
the input signal.
Features
Wide operating voltage range: 2 to 16 V
Battery powered application due to low quiescent
supply current: 2.7 mA typical
Chip disable input to power down the integrated
circuit
Low power down quiescent current
Drives a wide range of speaker loads
Output Power, P
o
= 250 mW @ R
L
= 32 (speaker)
Low harmonic distortion (0.5% typical)
Wide range gain adjustable: 0 dB to 46 dB
Benefits
Low number of external components
Low current consumption
