MAX987/MAX988/MAX991/ High-Speed, Micropower, Low-Voltage, MAX992/MAX995/MAX996 Rail-to-Rail I/O Comparators General Description Benefits and Features The MAX987/MAX988/MAX991/MAX992/MAX995/ 120ns Propagation Delay MAX996 single/dual/quad micropower comparators 48A Quiescent Supply Current feature low-voltage operation and rail-to-rail inputs and +2.5V to +5.5V Single-Supply Operation outputs. Their operating voltage ranges from +2.5V to +5.5V, making them ideal for both 3V and 5V systems. Common-Mode Input Voltage Range Extends 250mV Beyond the Rails These comparators also operate with 1.25V to 2.75V dual supplies. They consume only 48A per comparator Push-Pull Output Stage Sinks and Sources while achieving a 120ns propagation delay. 8mA Current (MAX987/MAX991/MAX995) Input bias current is typically 1.0pA, and input offset voltage Open-Drain Output Voltage Extends Beyond V CC is typically 0.5mV. Internal hysteresis ensures clean output (MAX988/MAX992/MAX996) switching, even with slow-moving input signals. Unique Output Stage Reduces Output Switching The output stages unique design limits supply-current Current, Minimizing Overall Power Consumption surges while switching, virtually eliminating the supply 100A Supply Current at 1MHz Switching glitches typical of many other comparators. The MAX987/ Frequency MAX991/MAX995 have a push-pull output stage that No Phase Reversal for Overdriven Inputs sinks as well as sources current. Large internal output drivers allow rail-to-rail output swing with loads up to Available in Space-Saving Packages: 8mA. The MAX988/MAX992/MAX996 have an open-drain 5-Pin SC70 (MAX987/MAX988) output stage that can be pulled beyond V to 6V (max) CC 8-Pin MAX (MAX991/MAX992) above V . These open-drain versions are ideal for level EE translators and bipolar to single-ended converters. Ordering Information The single MAX987/MAX988 are available in tiny 5-pin PKG TOP PART PIN-PACKAGE SC70 packages, while the dual MAX991/MAX992 are MARK CODE available in ultra-small MAX package.
