DYNAMIC PERFORMANCE

AD5380-3 is calibrated using an external 1.25 V reference. Temperature range is –40°C to +85°C.
Accuracy guaranteed from VOUT = 10 mV to AVDD – 50 mV.
Guaranteed by characterization, not production tested.
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.
Guaranteed by design and characterization, not production tested.
The slew rate can be programmed via the current boost control bit (CR11) in the AD5380 control register.
