UTCMC34119, LOW POWER AUDIO AMPLIFIER

The UTC MC34119 is a low power audio amplifier integrated circuit, 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, a
