_______________General Desc ription
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 sys-
tems. These comparators also operate with ±1.25V to
±2.75V dual supplies. They consume only 48μA per
comparator while achieving a 120ns propagation delay.
The common-mode input voltage range extends 250mV
beyond the supply rails. 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. This design
also minimizes overall power consumption under
dynamic conditions. 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 V
CC
to 6V (max)
above V
EE
. These open-drain versions are ideal for
level translators and bipolar to single-ended converters.
The single MAX987/MAX988 are available in tiny 5-pin
SOT23 packages.
