PURPOSE: An AD(Analog-to-Digital) conversion device for error compensation is provided to output a digital signal through more accurate AD conversion. CONSTITUTION: An AD conversion device(100) includes an analog signal input unit(110), an AD conversion unit(120), a constant number generation unit(140), and a digital signal output unit(130). The analog signal input unit generates an analog voltage value by receiving an analog signal from an external sensor(10). The AD conversion unit converts an analog voltage value into a digital signal. The constant number generation unit generates at least one compensation constant number for compensating an error in the analog voltage value. The digital signal output unit outputs the digital signal in which an error is compensated by applying a compensation constant number to the digital signal.
