Output unloaded. 4 See the Terminology section. 5 Offset error calculated using a reduced code range—AD5064/AD5064-1: Code 512 to Code 65,024; AD5044: Code 128 to Code 16,256; AD5024: Code 32 to Code 4064. Output unloaded 6 Guaranteed by design and characterization; not production tested. 7 Time to exit power-down mode to normal mode; 32nd clock edge to 90% of DAC midscale value, output unloaded. 8 Current flowing into individual digital pins. VDD = 5.5 V; VREF = 4.096 V; Code = midscale. 9 AD5064-1 only. 10 Interface inactive. All DACs active. DAC outputs unloaded. 11 All four DACs powered down. AC CHARACTERISTICS VDD = 4.5 V to 5.5 V, RL = 5 kΩ to GND, CL = 200 pF to GND, 2.5 V ≤ VREFIN ≤ VDD. All specifications TMIN to TMAX, unless otherwise noted. Table 3.
