A at reverse voltage (V
R
)=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 actually provided by an external V
IN
source is represented by "No-Load Input
Current (I

)".
