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
DD with a 0.1µF capacitor to
ground as close to the device as possible.
