NOTES
1
AD5380-3 is calibrated using an external 1.25V reference. Temperature range is -40°C to +85°C.
2
Guaranteed by characterization. Not production tested.
3
Accuracy guaranteed from Vout = 10mV to AV
-50mV
4
Default on the AD5380-3 is 1.25V. Programmable to 2.5V via CR12 in the AD5380 control register but operating the AD5380-3 with
a 2.5V reference will lead to degraded accuracy specifications and limited input code range.
Specifications subject to change without notice.
