10 Layout

10.1 Layout Guidelines

•

Place the power-supply bypass capacitor as closely as possible to the supply and ground pins. The

recommended value of this bypass capacitor is 0.1 µF. Add decoupling capacitance to compensate for noisy

or high-impedance power supplies.

•

Make sure that the thermal pad and GND are connected to a solid ground plane of the PCB.

•

Pull up the open-drain output pin to the supply voltage rail through a 10-kΩ pullup resistor.
