General Description

The MAX9100/MAX9101 micropower comparators are
optimized for single-cell systems, and are fully speci­fied for operation from a single supply of 1.0V to 5.5V.
This ultra-low voltage operation, 5µA 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 sig­nal voltage. In addition, propagation delay is less than
4µs, 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
