Test Conditions/Comments

All digital inputs

VDD = 3 V

VDD = 3 V

All digital inputs at 0 or VDD,

DAC active, excludes load current

VIH = VDD and VIL = GND

VIH = VDD and VIL = GND

1 Temperature range is −40°C to +105°C, typical at 25°C.

2 Linearity calculated using a reduced code range of AD5628 (Code 32 to Code 4064), AD5648 (Code 128 to Code 16256), and AD5668 (Code 512 to 65024). Output

unloaded.

3 Guaranteed by design and characterization; not production tested.

4 Interface inactive. All DACs active. DAC outputs unloaded.

5 All eight DACs powered down.

AC CHARACTERISTICS

VDD = 2.7 V to 5.5 V, RL = 2 kΩ to GND, CL = 200 pF to GND, VREFIN = VDD. All specifications TMIN to TMAX, unless otherwise noted.
