The MAX907/MAX908/MAX909 are dual/quad/single,
high-speed, ultra-low-power voltage comparators
designed for use in systems powered from a single
+5V supply; the MAX909 also accepts dual ±5V supplies.
Their 40ns propagation delay (with 5mV input
overdrive) is achieved with a power consumption of
only 3.5mW per comparator. The wide input common-mode
range extends from 200mV below ground (below
the negative supply rail for the MAX909) to within 1.5V
of the positive supply rail.
Because they are micropower, high-speed comparators
that operate from a single +5V supply and include
built-in hysteresis, these devices replace a variety of
older comparators in a wide range of applications.
MAX907/MAX908/MAX909 outputs are TTL-compatible,
requiring no external pullup circuitry. All inputs and outputs
can be continuously shorted to either supply rail
without damage. These easy-to-use comparators incorporate
internal hysteresis to ensure clean output switching
even when the devices are driven by a slow-moving
input signal.
The MAX909 features complementary outputs and an
output latch. A separate supply pin for extending the
analog input range down to -5V is also provided.
The dual MAX907 and single MAX909 are available in
8-pin DIP and SO packages, and the quad MAX908 is
available in 14-pin DIP and SO packages. These comparators
are ideal for single +5V-supply applications
that require the combination of high speed, precision,
and ultra-low power dissipation.
