________________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 48A per compara-
tor while achieving a 120ns propagation delay.
Input bias current is typically 1.0pA, and input offset volt-
age 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 inter-
nal 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.
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 MAX pack-
ages.
