U4083B Low-Power Audio Amplifier for Telephone Applications

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 adju.
