5. Timing component limitations
The capacitor used in the circuit should be non-polarized and have low leakage (i.e. the parallel resistance of the
capacitor should be an order of magnitude greater than the external resistor used).
There is no upper or lower limit for either R
However, in consideration of accuracy, C
this capacitance can be measured and taken into account).
R
The recommended values for R
should be:
6. Power consumption
In the standby mode (monostable or astable), power dissipation will be a function of leakage current in the circuit.
For dynamic operation, the power needed to charge the external timing capacitor C
Because the power dissipation does not depend on R
of C
Typical power consumption in astable mode is shown in Figs 10, 11 and 12.
