Single/Dual/Quad, Micropower, Ultra-Low-Voltage, Rail-to-Rail I/O Comparators
General DescriptionThe MAX965–MAX970 single/dual/quad micropower
comparators feature rail-to-rail inputs and outputs, and
fully specified single-supply operation down to +1.6V.
These devices draw less than 5µA per comparator and
have open-drain outputs that can be pulled beyond VCC
to 6V (max) above ground. In addition, their rail-to-rail
input common-mode voltage range makes these com-
parators suitable for ultra-low-voltage operation.
A +1.6V to +5.5V single-supply operating voltage range
makes the MAX965 family of comparators ideal for 2-cell
battery-powered applications. The MAX965/MAX967/
MAX968/MAX969 offer programmable hysteresis and
an internal 1.235V ±1.5% reference. All devices are
available in either space-saving 8-pin µMAX®or 16-pin
QSOP packages.

________________________________________________Pin Descriptions (continued)
_______________Detailed DescriptionThe MAX965–MAX970 single/dual/quad, micropower,
ultra-low-voltage comparators feature rail-to-rail inputs
and outputs and an internal 1.235V ±1.5% bandgap
reference. These devices operate from a single +1.6V
to +5.5V supply voltage range, and consume less than
5µA supply current per comparator over the extended
temperature range. Internal hysteresis is programmable
up to ±50mV using two external resistors and the
device’s internal reference. The rail-to-rail input com-
mon-mode voltage range and the open-drain outputs
allow easy voltage-level conversion for multivoltage
systems. All inputs and outputs can tolerate a continu-
ous short-circuit fault condition to either rail.
The MAX965 is a single comparator with adjustable
hysteresis and a reference output pin. The MAX966 is a
dual comparator without the reference and without
tor configured as a dual voltage monitor with common
hysteresis adjustment and a reference output. The dual
MAX968 is similar to the MAX967, but is configured as
a window comparator. The MAX969 is a quad com-
parator with a common hysteresis adjustment and a ref-
erence output pin. The MAX970 is a quad comparator
without a reference and without hysteresis adjustment.
(See Functional Diagrams and Selector Guide.)
Comparator InputThe MAX965–MAX970 have a -0.25V to VCCinput com-
mon-mode range. Both comparator inputs may operate
at any differential voltage within the common-mode
voltage range, and the comparator displays the correct
output logic state.
Low-Voltage Operation: VCCDown to 1V The minimum operating voltage is 1.6V. As the supply
voltage falls below 1.6V, performance degrades
