Condition Min. Typ. Max. Unit
* In case of the voltage measurement mode or differential voltage measurement mode, the reference voltage VR2 is
adjusted so that the measurement error (absolute error E) of the A/D converter becomes minimum when Ta = 25°C, VDD
= VDDA = 3 A, input voltage VIN = +320 mV.
Error and deviation by the reference voltage VR2 are not included.
See Chapter 6, "BASIC EXTERNAL CONNECTION DIAGRAM", for the circuit to be measured.
