HI7131 Description

The Intersil HI7131 and HI7133 are 31/2 digit, A/D converters that have been optimized for superior DC mon Mode Rejection (CMRR) when used with a split ±5V supply or a single 9V battery. The HI7131 contains all the necessary active ponents on a single IC to directly interface an LCD (Liquid Crystal Display). The supply current is under 100µA and is ideally suited for battery operation.
