MAX966

MAX965–MAX970 19-1226; Rev 3; 2/07 Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators General Description The MAX965–MAX970 single/dual/quad micropower comparators feature rail-to-rail inputs and outputs, and fully specified single-supply operation down to +1.6V. These devices draw less than 5µA per comparator and have open-drain outputs that can be pulled beyond VCC to 6V (max) above ground. In addition, their rail-to-rail input common-mode voltage range makes these comparators suitable for ultra-low-voltage operation. A +1.6V to +5.5V single-supply operating voltage range makes the MAX965 family of comparators ideal for 2-cell battery-powered applications. The MAX965/MAX967/ MAX968/MAX969 offer programmable hysteresis and an internal 1.235V ±1.5% reference. All devices are available in either space-saving 8-pin µMAX® or 16-pin QSOP packages. ________________________Applications 2-Cell Battery-Powered/Portable Systems Window Comparators Threshold Detectors/Discriminators Mobile Communications Voltage-Level Translation Ground/Supply-Sensing Applications _____________________Selector Guide ____________________________Features ♦ Ultra-Low Single-Supply Operation down to +1.6V ♦ Rail-to-Rail Common-Mode Input Voltage Range ♦ 3µA Quiescent Supply Current per Comparator ♦ Open-Drain Outputs Swing Beyond VCC ♦ 1.235V ±1.5% Precision Internal Reference (MAX965/967/968/969) ♦ 10µs Propagation Delay (50mV overdrive) ♦ Available in Space-Saving Packages: ...
