■ APPLICATION CIRCUIT
( note )
1. The NJM2135 is active mode during the CD terminal is High level ( >2.0V )
2. C1 and C2 improve power supply rejection ratio.
3. Please note that the C1 and C2 make slow power rise up to the NJM2135
4. Input current flow on the internal resistor shown in the equivalent circuit of
5. No snubber resistor and capacitor are required normally. But the snubber
6. When the NJM2135 change the mode to active or stand-by the CD terminal
7. When the power turns on in stand-by mode,the NJM2135 operates during
8. If the supply voltage fluctuate large during the stand-by mode,the mode of
