1 AD5381-5 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 AD5381-5 is 2.5 V. Programmable to 1.25 V via CR10 in the AD5381 control register; operating the AD5381-5 with a 1.25 V reference will lead to
degraded accuracy specifications.
