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
