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.
