Conditions/Comments
All digital inputs at 0 or VDD,
DAC active, excludes load current
VIH = VDD and VIL = GND
Internal reference off
Internal reference on
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 the AD5629R (Code 32 to Code 4064) and the AD5669R (Code 512 to 65,024). 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.
