... Data Sheet BiMOS Dual Voltage Comparators with MOSFET Input, Bipolar Output The CA3290A and CA3290 types consist of a dual voltage comparator on a single monolithic chip. The common mode input voltage range includes ground even when operated from a single supply. The low supply current drain makes these comparators suitable for battery operation ...
