LMH7220 is a high speed, low power comparator from National Semiconductor Corporation. It has a supply voltage range of 2.7V to 12V and an output voltage of 325 mV. It can drive a 100Ω symmetrical transmission line. LMH7220 has a propagation delay of 2.9 ns, rise and fall times of 0.6 ns, and a supply current of only 6.8 mA. It has a voltage range of 200 mV below ground, making it suitable for ground sensing applications. LMH7220 is available in both 6-pin SOT and SC-70 packages.
The LMH7220 is a high‑speed, low‑power comparator that operates from 2.7 V to 12 V and features a differential LVDS output driving 325 mV into a 100 Ω line. It provides a 2.9 ns propagation delay and 0.6 ns rise/fall times while consuming only 6.8 mA at 5 V (load current excluded).\n\nThe device is offered in 6‑Pin TSOT and SC‑70 packages, with detailed absolute maximum ratings, electrical characteristics, and typical performance graphs. Ordering information, physical dimensions, and recommended land patterns are included for PCB designers.
