LOW VOLTAGE AUDIO POWER AMPLIFIER

■ GENERAL DESCRIPTION

■ PACKAGE OUTLINE

The NJM2113 is an audio power amplifier designed for telephone

application, such as in speakerphones. Coupling capacitors to the

speaker are not required,as it has differential speaker outputs.

The closed loop gain is set with two external resistors.

A CD pin permit powering down with muting the input signal.
