Power-Supply Considerations

On power-up, the input and DAC registers are cleared

(set to zero code).

For rated MAX5354/MAX5355 performance, REF must

be at least 1.4V below V

. Bypass V

with a 4.7µF

capacitor in parallel with a 0.1µF capacitor to GND.

Use short lead lengths and place the bypass capaci-

tors as close to the supply pins as possible.

Grounding and Layout Considerations

Digital or AC transient signals on GND can create noise

at the analog output. Tie GND to the highest-quality

ground available.

Good printed circuit board ground layout minimizes

crosstalk between the DAC output, reference input, and

digital input. Reduce crosstalk by keeping analog lines

away from digital lines. Wire-wrapped boards are not

recommended.
