1
Temperature range: −40°C to +105°C; typical at +25°C.
2
Total unadjusted error is the total measured error (offset error + gain error + linearity error + output drift over temperature) after factory calibration of the AD5421.
System level total error can be reduced using the offset and gain registers.
3
Guaranteed by design and characterization; not production tested.
4
The voltage between LOOP− and REG
IN
must be 5.5 V or greater.
5
The AD5421 is factory calibrated with an external 2.5 V reference connected to REFIN.
6
This is the current that the output is capable of sourcing. The load current originates from the loop and, therefore, contributes to the total current consumption figure.
