APPLICATION CIRCUIT 1
DO is an open – drain output and requires a pull-high resistor between 1KΩ to 10KΩ. The pull-up
A capacitor must be added to the power line so that both the power supply voltage (VDD) rise
time when power is applied and the power supply voltage (VDD) fall time when power drops are
at least 1ms.
resistor value must be appropriate to the capacitor of the external wiring so that the signal wave
forms are not degraded.
