General Description
The MAX9075/MAX9077 single/dual comparators are
optimized for 3V and 5V single-supply applications.
These comparators have a 580ns propagation delay and
consume just 3µA per comparator. The combination of
low-power, single-supply operation down to 2.1V, and
ultra-small footprint makes these devices ideal for all
portable applications.
The MAX9075/MAX9077 have a common-mode input
voltage range of -0.2V to V
CC
- 1.2V. Unlike many com-
parators, there is no differential clamp between the
inputs, allowing the differential input voltage range to
extend rail-to-rail. All inputs and outputs tolerate a con-
tinuous short-circuit fault condition to either rail.
The design of the output stage limits supply-current
surges while switching (typical of many other compara-
tors), minimizing power consumption under dynamic
conditions. Large internal push-pull output drivers allow
rail-to-rail output swing with loads up to 2mA, making
these devices ideal for interface with TTL/CMOS logic.
The MAX9075 single comparator is available in 5-pin
SC70 and SOT23 packages, while the MAX9077
dual comparator is available in 8-pin SOT23, µMAX
®
,
and SO packages.
