Temperature range: −40°C to +105°C; typical at +25°C.
Specifications guaranteed by design and characterization; not production tested.
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.
