Rainbow Electronics MAX996 - Manual

________________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 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.
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 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
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
SC70 packages, while the dual MAX991/MAX992 are
available in ultra-small 8-pin SOT23 packages.
