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.
