Overview
19-1266; Rev 2; 1/07 MAX987/MAX988/MAX991/MAX992/MAX995/MAX996 High-Speed, Micropower, Low-Voltage, SOT23, Rail-to-Rail I/O Comparators ________________General Description 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 singleended converters.
The single MAX987/MAX988 are available in tiny 5-pin SC70 packages, while the dual MAX991/MAX992 are available in ultra-small 8-pin SOT23 and µMAX® packages.
