calculated to be 4.00kΩ. The current DAC in this con-
figuration allows the output voltage to be moved linearly
from +1.6V to +2.4V using 127 settings. This corre-
sponds to a resolution of 6.3mV/step.
To achieve the best results when using the DS4426,
decouple the power supply with a 0.01µF (or 0.1µF)
capacitor. Use a high-quality, ceramic, surface-mount
capacitor if possible. Surface-mount components mini-
mize lead inductance, which improves performance.
Ceramic capacitors tend to have adequate high-fre-
quency response for decoupling applications.
