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 extremely high source impedances.
Package options are shown in the table below.
