NJM2113 LOW VOLTAGE AUDIO POWER AMPLIFIER GENERAL DESCRIPTION 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.

The NJM2113 is active mode during the CD terminal is Low level ( <0.8V ) and it is stand-by mode during the CD terminal is High level ( >2.0V ) 2. C1 and C2 improve power supply rejection ratio. In case of C1 is enough large,C2 is unnecessary. 3. Please note that the C1 and C2 make slow power rise up to the NJM2113 regardless the external power supply condition. 4. Input current flow on the internal resistor shown in the equivalent circuit of CD terminal. 5. No snubber resistor and capacitor are required normally. But the snubber resistor and capacitor are required if the NJM2113 oscillates by Condition of PCB layout,stray capacitor and speaker wire length.
