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, 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

allows almost all of the power supply to be used for sig-

nal 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.
