AD5380-3 is calibrated using an external 1.25 V reference. Temperature range is –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 AD5380-3 is 1.25 V. Programmable to 2.5 V via CR12 in the AD5380 control register; operating the AD5380-3 with a 2.5 V reference will lead to degraded

accuracy specifications and limited input code range.

AC CHARACTERISTICS1

AVDD = 2.7 V to 3.6 V or 4.5 V to 5.5 V; DVDD = 2.7 V to 5.5 V; AGND = DGND = 0 V.
