MC34119 - Low Power Audio Amplifier

General Description

The MC34119 is a low power audio amplifier integrated circuit intended (primarily) for telephone applications, such as in speakerphones.

It provides differential speaker outputs to maximize output swing at low supply voltages (2.0V minimum).

Coupling capacitors to the speaker are not required.

Key Features

  • Wide Operating Supply Voltage Range (2.0V to 16V), Allows Telephone Line Powered.
