General Description
The MAX9107/MAX9108/MAX9109 dual/quad/single,
high-speed, low-power voltage comparators are
designed for use in systems powered from a single
+5V supply. Their 25ns propagation delay (with 10mV
input overdrive) is achieved with a power consumption
of only 1.75mW per comparator. The wide input com-
mon-mode range extends from 200mV below ground
to within 1.5V of the positive supply rail.
The MAX9107/MAX9108/MAX9109 outputs are TTL-
compatible, requiring no external pullup circuitry.
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 MAX9107/MAX9108/MAX9109 are higher-speed,
lower-power, lower-cost upgrades to industry-standard
comparators MAX907/MAX908/MAX909. The MAX9109
features an output latch but does not have comple-
mentary outputs.
The dual MAX9107 is available in both 8-pin SO and
SOT23 packages. The quad MAX9108 is available in
14-pin TSSOP and SO packages while the single
MAX9109 is available in an ultra-small 6-pin SC70
package, a space-saving 6-pin SOT23 package and
an 8-pin SO package.
