MC34119 Datasheet (UTC) - LOW POWER AUDIO AMPLIFIER

MC34119, LOW POWER AUDIO AMPLIFIER

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 loo
