See the Terminology section.
Temperature range (A, B, W Version): −40°C to +105°C; typical at +25°C.
DC specifications tested with the outputs unloaded.
Linearity is tested using a reduced code range: AD5304 (Code 8 to Code 248); AD5314 (Code 28 to Code 995); AD5324 (Code 115 to Code 3981).
Guaranteed by design and characterization, not production tested.
For the amplifier output to reach its minimum voltage, offset error must be negative. For the amplifier output to reach its maximum voltage, V
gain error must be positive.
