10 Layout

10.1 Layout Guidelines

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

value of this bypass capacitor is 0.01 μF. Additional decoupling capacitance can be added to compensate for

noisy or high-impedance power supplies.

Pull up the open-drain output pins (SDA and ALERT) to a supply voltage rail (VS or higher but up to 3.6 V)

through 10-kΩ pull-up resistors.
