The MAX985/MAX986/MAX989/MAX990/MAX993/

MAX994 single/dual/quad micropower comparators

feature low-voltage operation and rail-to-rail inputs and

outputs. Their operating voltages range 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 11µA of supply cur-

rent while achieving a 300ns 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

MAX985/MAX989/MAX993 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 MAX986/MAX990/MAX994 have

an open-drain output stage that can be pulled beyond

are ideal for level translators and bipolar to single-

ended converters.

The single MAX985 is available in a chip-scale pack-

age (UCSP™), significantly reducing the required PC

board area. The single MAX985/MAX986 are available

in 5-pin SC70 packages and the dual MAX989/MAX990

are available in 8-pin SOT23 packages.
