Low Power Audio Amplifier

(primarily) for telephone applications, such as in speakerphones. It provides

differential speaker outputs to maximize output swing at low supply voltages

(2.0 V minimum). Coupling capacitors to the speaker are not required. Open

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

A Chip Disable pin permits powering down and/or muting the input signal.

The MC34119 is available in standard 8–pin DIP, SOIC package, and

TSSOP package.

NOTE: ESD data available upon request.
