Rail-to-Rail CMOS COMPARATOR
S-89530A/89531A
The mini analog series is a group of ICs that incorporate a general-
purpose analog circuit in an ultra-small packages.
The S-89530A/89531A Series are CMOS type comparators that
feature Rail-to-Rail
*1
I/O and can be driven at a lower voltage and
lower current consumpsion than existing comparators, making the S-
89530A/89531A for use in battery-powered compact portable
devices.
