General Description
The MAX9100/MAX9101 micropower comparators are
optimized for single-cell systems, and are fully speci-
fied for operation from a single supply of 1.0V to 5.5V.
This ultra-low voltage operation, 5A quiescent current
consumption,
and
small
footprint
make
the
MAX9100/MAX9101 ideal for use in battery-powered
systems. A wide-input common-mode range that
includes the negative rail and rail-to-rail output swing
allows almost all of the power supply to be used for sig-
nal voltage. In addition, propagation delay is less than
4s, and rise and fall times are 100ns.
The MAX9100 features a push-pull CMOS output stage
that sinks and sources current with large internal output
drivers that allow rail-to-rail output swings with loads up
to 5mA.The MAX9101 has an open-drain output stage
that makes it suitable for mixed-voltage designs.
The MAX9100/MAX9101 are available in tiny SOT23-5
packages.
