Abstract
A trimming resistor network includes first and second external connection terminals, a first resistor having two ends acting as first and second connection terminals, a first coupling body for connecting the first external connection terminal to the first connection terminal via series-connected resistors, a second coupling body for connecting the second external connection terminal to the second connection terminal directly or via series-connected resistors, and parallel trimming resistors having two ends respectively connected to the first and second coupling bodies. The combined resistance between the first and second external connection terminals is increased by substantially a preset amount each time one of the parallel trimming resistors is cut off.
