With respect to COM

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 REGIN 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.
