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.
