Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit for much more highly accurately outputting constant currents.SOLUTION: A semiconductor integrated circuit includes a first contact current output circuit for outputting first constant currents from a first contact current terminal to a first output terminal. The semiconductor integrated circuit includes an error current output circuit for outputting error currents from an error current terminal to the first output terminal. The error current output circuit includes a current comparison circuit for comparing monitor currents obtained by monitoring output currents output from the first output terminal with reference currents, and for outputting first comparison result currents obtained by subtracting the monitor currents from the reference currents, and for outputting second comparison result currents obtained by subtracting the reference currents from the monitor currents. The error current output circuit includes a first amplifier circuit for outputting first amplified currents with first polarity obtained by amplifying the first comparison result currents. The error current output circuit includes a second amplifier circuit for outputting second amplified currents with second polarity which is opposite to the first polarity obtained by amplifying the second comparison result currents. |
