摘要： A current detection device for a multi-sensor array is provided. The current detection device includes a current input unit, a current conversion unit, a digital conversion unit, and a voltage applying unit. The current input unit amplifies a plurality of current signals input from a multi-sensor array according to a predetermined current minor ratio, and fixes each of node voltages to which the plurality of current signals are input. The current conversion unit converts each of the amplified current signals into an amplified voltage signal using a plurality of feedback resistors and an operational amplifier which are connected in parallel. The digital conversion unit converts each of the amplified voltage signals converted by the current conversion unit into a digital value. The voltage applying unit generates voltages for driving each of the multi-sensor array, the current input unit, the current conversion unit, and the digital conversion unit, and applies the generated voltages thereto.
