the digital input serially into the DAC. Schmitt-trigger
buffered inputs allow slow transition interfaces such as
optocouplers to interface directly to the device. The
digital inputs are compatible with CMOS logic levels.
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
ground as close to the device as possible.
