MAX965–MAX970

_______________Detailed Description
The 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
5A 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
adjustable hysteresis. The MAX967 is a dual compara-
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 Input
The MAX965–MAX970 have a -0.25V to VCC input 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: VCC Down to 1V
The minimum operating voltage is 1.6V. As the supply
voltage falls below 1.6V, performance degrades
and supply current falls. The reference does not
