AD5384-3 is calibrated using an external 1.25 V reference. Temperature range is –40°C to +85°C.
Accuracy guaranteed from V
Guaranteed by characterization, not production tested.
Default on the AD5384-3 is 1.25 V. Programmable to 2.5 V via CR12 in the AD5384 control register; operating the AD5384-3 with a 2.5 V reference will lead to degraded
accuracy specifications and limited input code range.
