1. Description

The integrated circuit U4083B is a low-power audio amplifier for telephone loudspeak-

ers. 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 where the closed-loop gain is adjusted with two external resistors. A chip dis-

able pin permits powering down and/or muting the input signal.
