3 DC specifications tested with the outputs unloaded.
4 Linearity is tested using a reduced code range: AD5302 (Code 8 to 248); AD5312 (Code 28 to 995); AD5322 (Code 115 to 3981).
5 Guaranteed by design and characterization, not production tested.
6 In order for the amplifier output to reach its minimum voltage, offset error must be negative. In order for the amplifier output to reach its maximum voltage,
VREF = VDD and offset plus gain error must be positive.
AC SPECIFICATIONS
VDD = 2.5 V to 5.5 V, RL = 2 kΩ to GND, CL = 200 pF to GND, all specifications TMIN to TMAX, unless otherwise noted.1
