The CA3290A and CA3290 types consist of a dual voltagecomparator on a single monolithic chip. The common modeinput voltage range includes ground even when operatedfrom a single supply. The low supply current drain makesthese comparators suitable for battery operation; theirextremely low input currents allow their use in applicationsthat employ sensors with extremely high sourceimpedances. Package options are shown in the table below.
