In the above graph the errors values are shown in Current Mode.
Down to 5mA %Meas_Ierr1 and below 5mA IMeas_Ierr2.
For instance for Isense > 5mA, then V_{MEASOUT_ISENSE} ~ Isense +/-5%
Remarks:
• The error over the total chain in CM (%Meas_Ierrx) does not include error due to the external
RREF resistor.
• In the full system calculation additional errors have to be added for the tolerances on the sensor
current, the ADC supply noise, etc.
