CA3290, CA3290A Data Sheet September 1998 File Number 1049.3 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; their extremely low input currents allow their use in applications that employ sensors with extremel
