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

²Linearity calculated using a reduced code range: AD5663R (Code 512 to Code 65,024), AD5643R (Code 12± to Code 16,256), and AD5623R (Code 32 to Code 4064).

Output unloaded.

³Guaranteed by design and characterization, not production tested.

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

⁵Both DACs powered down.

AC CHARACTERISTICS

V_DD= 2.7 V to 5.5 V; R_L= 2 kΩ to GND; C_L= 200 pF to GND; V_REFIN= V_DD; all specifications T_MINto T_MAX, unless otherwise noted.
