Product Details
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 common- 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 complementary
outputs.
Applications
