1. An ADC error compensation control device comprising:
an ADC module configured to calculate a first result value using a sensed input voltage Vin and an input reference voltage Vref, and calculate a second result value using an input MCU supply voltage and the input reference voltage Vref;
an error compensation unit configured to calculate an error compensation value on the basis of the second result value calculated by the ADC module, the MCU supply voltage, and a steady state value of the reference voltage Vref; and
a logic unit configured to calculate a real value on the basis of the error compensation value from the first result value.
