PROBLEM TO BE SOLVED: To provide an electronic control device capable of securing accuracy of A/D conversion when a filter composed of a resistor and a capacitor is provided by being shared by a plurality of input channels.SOLUTION: An electronic control device 10 is so configure that a time constant of a filter composed of a resistor section 24 and an input capacitance section 261 can be changed by a changeover instruction section 264. The changeover instruction section 264 changes a time constant so that electricity sufficient for performing conversion processing at an A/D conversion execution section 263 is charged to the input capacitance section 261.SELECTED DRAWING: Figure 1 |
