optocouplers to interface directly to the device. The

digital inputs are compatible with CMOS logic levels.

Power-Supply Bypassing and

Ground Management

Careful PC board layout is important for optimal system

performance. Keep analog and digital signals separate

to reduce noise injection and digital feedthrough. Use a

ground plane to ensure that the ground return from

GND to the power-supply ground is short and low

impedance. Bypass V

with a 0.1µF capacitor to

ground as close to the device as possible.
