MAX987/MAX988/MAX991/
MAX992/MAX995/MAX996
General Description
High-Speed, Micropower, Low-Voltage,
Rail-to-Rail I/O Comparators
Benefits and Features
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 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 μMAX
®
package.
