概述The MAX987/MAX988/MAX991/MAX992/MAX995/ MAX996 single/dual/quad micropower comparators feature low-voltage operation and rail-to-rail inputs and outputs. Their operating voltage ranges from 2.5V to 5.5V, making them ideal for both 3V and 5V systems. These comparators also operate with ±1.25V to ±2.75V dual supplies. They consume only 48μA per comparator while achieving a 120ns propagation delay.Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals.The output stage's unique design limits supply-current surges while switching, virtually eliminating the supply glitches typical of many other comparators. The MAX987/MAX991/MAX995 have a push-pull output stage that sinks as well as sources current. Large internal output drivers allow rail-to-rail output swing with loads up to 8mA. The MAX988/MAX992/MAX996 have an open-drain output stage that can be pulled beyond VCC to 6V (max) above VEE. These open-drain versions are ideal for level translators and bipolar to single-ended converters关键特性120ns Propagation Delay48μA Quiescent Supply Current 2.5V to 5.5V Single-Supply OperationCommon-Mode Input Voltage Range Extends 250mV Beyond the RailsPush-Pull Output Stage Sinks and Sources 8mA Current (MAX987/MAX991/MAX995)Open-Drain Output Voltage Extends Beyond VCC (MAX988/MAX992/MAX996)Unique Output Stage Reduces Output Switching Current, Minimizing Overall Power Consumption100μA Supply Current at 1MHz Switching FrequencyNo Phase Reversal for Overdriven InputsAvailable in Space-Saving Packages:5-Pin SOT23 (MAX987/MAX988)8-Pin μMAX (MAX991/MAX992)应用/使用数字线接收器地/电源检测IR接收器电平转换器移动通信便携式电池供电系统门限检测器窗比较器过零检测器
