MAX985/MAX986/MAX989/
MAX990/MAX993/MAX994
Micropower, Low-Voltage, UCSP/SC70,
Rail-to-Rail I/O Comparators
General Description
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
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 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.
