Abstract

PURPOSE: To improve the precision with a simple configuration by using a LSI, which is formed on one silicon chip, for the A/D converter circuit that involves from analog input element to display driver.
CONSTITUTION: The input signal and the reference voltage source 10 are changed by the input changeover analog switch group 4 and are integrated by the integrating circuit 5, the digital signal 13 corresponding to the input signal is provided to the output through the comparator 6. The digital signal 13 is applied to the display element 7, which is installed on the outside of the device, through the control logic circuit 7 and display driver 8. Moreover the input attenuators 2-1, 2-2, 2-3 are provided to the device and a group that includes the rectifier circuit 3 and analog switch control circuit 15 is made the LSIed block 16.
