Low-Power, 13-Bit Voltage-Output DACs
with Serial Interface
On power-up, the input and DAC registers are cleared
(set to zero code).
For rated MAX535/MAX5351 performance, REF should
be at least 1.4V below V
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.

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.
