MAX9101 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 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.
