All voltages are referenced to V SS .
Factory-calibrated accuracy. Higher accuracy can be achieved by in-system calibration by the user.
Parameters guaranteed by design.
At a constant regulated V DD voltage, the Current Offset Bias register can be used to obtain higher accuracy.
Accumulation Bias register set to 00h.
EEPROM data retention is 10 years at +50°C.
