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.
