Test Conditions/Comments
IDD specification is valid for all DAC codes
Both DACs active and excluding load currents
Both DACs in unbuffered mode, VIH = VDD and
VIL = GND; in buffered mode, extra current is
typically × μA per DAC where x = 5 μA + VREF/RDAC
1 _{Temperature range: A, B version: –40°C to +105°C.}
2 _{See Terminology section.}
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
