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 V
IN
source is represented by “No-Load Input Current (I
IN
)”
