<p><P>PROBLEM TO BE SOLVED: To provide an input circuit which is easy to carry out the input operation, while suppressing increase in power consumption and increase in the number of resistive elements. <P>SOLUTION: The input circuit 100 includes a first circuit part 10 having resistive elements 11, 12, 13; a second circuit part 20, arranged in parallel to the first circuit part 10 and having resistive elements 21, 22; a plurality of switches 30a-30i which can individually form a plurality of mutually different electric pathways from a power supply 110 to a ground 120, by connecting nodes N1-N3 of the first circuit part 10 and nodes N4-N6 of the second circuit part 20, and respectively go into non-connecting states in normal state; and an output terminal 40 for outputting a voltage divided by the resistive element of the first circuit part 10 and the resistive element of the second circuit part 20, corresponding to a predetermined electric pathway, when a predetermined electric pathway is formed by connecting one switch out of the plurality of switches. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
