Notes:
1. The Schottky diode (S.D.), in figure 3 must be type MA735, with Reverse current (IR) < 1.0µA at reverse voltage
(VR)=10.0V
2. “Supply Current 1” is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator
periodically operates which results in less average power consumption.
The current that is actually provided by external VIN source is represented by “No-Load Input Current (IIN)”
