+1.0V Micropower SOT23 Comparators
General Description
____________________________Features
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 sig-
nal voltage. In addition, propagation delay is less than
4µs, and rise and fall times are 100ns.
• Ultra-Low Voltage: Guaranteed Down to +1.0V
• Low Quiescent Current: 5µA
• Optimized for Single-Cell Battery-Powered
Systems
• Wide Input Common-Mode Range
• CMOS Rail-to-Rail Output Swing (MAX9100)
• Open-Drain Output (MAX9101)
• 4µs Propagation Delay
• High Output Drive Capability: 5mA Sink and
Source (MAX9100)
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.
• No Output Phase Reversal for Overdriven Inputs
• Available in Tiny SOT23-5 Package
The MAX9100/MAX9101 are available in tiny SOT23-5
packages.
