1 AD5382-5 is calibrated using an external 2.5 V reference. Temperature range for all versions: –40°C to +85°C.
2 Accuracy guaranteed from VOUT = 10 mV to AVDD – 50 mV.
3 Guaranteed by characterization, not production tested.
4 Default on the AD5382-5 is 2.5 V. Programmable to 1.25 V via CR12 in the AD5382 control register; operating the AD5382-5 with a 1.25 V reference leads to degraded
accuracy specifications.
