Temperature range: A, B version: –40°C to +105°C.
See Terminology section.
DC specifications tested with the outputs unloaded.
Linearity is tested using a reduced code range: AD5302 (Code 8 to 248); AD5312 (Code 28 to 995); AD5322 (Code 115 to 3981).
Guaranteed by design and characterization, not production tested.
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,
