■ APPLICATION CIRCUIT
INPUT
NJM2113
Power-Down Control
( note )
1. 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.
