NJM2113
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.
