1 Temperature range: B grade = −40°C to +105°C.

2 Linearity calculated using a reduced code range: AD5663R (Code 512 to Code 65,024), AD5643R (Code 128 to Code 16,256), and AD5623R (Code 32 to Code 4064).

Output unloaded.

3 Guaranteed by design and characterization, not production tested.

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

5 Both 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.
