DESCRIPTION

The UTC MC34119 is a low power audio amplifier IC intended for

the telephone applications, such as in speakerphones. It provides

differential speaker outputs to maximize output swing at low supply

voltages. Coupling capacitor to the speaker is not required. Open

loop gain is 80dB, and the closed loop gain is set with two external

resistors. The Mute pin permits powering down and/or muting the

input signal.
