AD5381-3 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 AD5381-3 is 1.25 V. Programmable to 2.5 V via CR10 in the AD5381 control register; operating the AD5381-3 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.
Slew rate can be programmed via the current boost control bit in the AD5381 control register.
