The UTC34119 is a low power audio amplifier integrated ircuit intended (primarily) for the telephone applications, uch as in speakerphones. It provides differential speaker utputs to maximize output swing at low supply voltages. oupling Capacitor to the speaker are not required. Open oop gain is 80dB, and the closed loop gain is set with two xternal resistors. A chips Disable pin permits powering own and/or muting the input signal.
