Rochester Electronics Linear - Comparators LT1720IMS8

The LT1720IMS8 is an UltraFast dual comparator optimized for single supply operation, with a supply voltage range of 2.7V to 6V. It features a propagation delay of 4.5ns at 20mV overdrive and 7ns at 5mV overdrive, making it suitable for high-speed applications. The input voltage range extends from 100mV below ground to 1.2V below the supply voltage, and it includes internal hysteresis for improved performance with slow-moving input signals. This comparator is designed with rail-to-rail outputs that are compatible with TTL and CMOS logic levels, allowing for versatile interfacing in various circuits. The LT1720IMS8 operates with a low power consumption of 4mA per comparator and has a low dynamic current drain of 15OºA/(V-MHz), which is advantageous for battery-powered applications. It is available in a compact 8-lead MSOP package, making it suitable for space-constrained designs. Typical applications include high-speed differential line receivers, crystal oscillator circuits, window comparators, and threshold detectors. The LT1720IMS8 is ideal for engineers seeking a high-performance comparator with low power requirements and a small footprint for their projects.
