Temperature range: −40°C to +105°C; typical at +25°C.
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.
Guaranteed by design and characterization; not production tested.
The voltage between LOOP− and REG
The AD5421 is factory calibrated with an external 2.5 V reference connected to REFIN.
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.
