CURRENT SIGNAL GENERATION CIRCUIT, CURRENT SIGNAL GENERATION IC CHIP

摘要

PROBLEM TO BE SOLVED: To provide a current signal generation circuit capable of controlling output characteristics of current with satisfactorily high accuracy.SOLUTION: A current signal generation circuit is provided with a plurality of output current sources 101-10k for outputting output currents Ito I. The output current sources 101-10k have a function for switching whether output currents Ito Iare outputted. A control circuit 123 receives a current output instruction signal V, and controls whether the output current sources output the output currents Ito I, based on the current output instruction signal V. The current signal generation circuit further includes a terminal 113 that outputs as output current Ithe sum of the output currents Ito Ioutputted from the plurality of output current sources 101-10k.
