LMH7220
LMH7220 is High Speed Comparator with LVDS Output manufactured by National Semiconductor.
Description
The LMH7220 is a high speed, low power parator with an operating supply voltage range of 2.7V to 12V. The LMH7220 has a differential, LVDS output, driving 325 m V into a 100Ω symmetrical transmission line. The LMH7220 has a 2.9 ns propagation delay and 0.6 ns rise and fall times while the supply current is only 6.8 m A at 5V (load current excluded). The LMH7220 inputs have a voltage range that extends 200 m V below ground, allowing ground sensing applications. The LMH7220 is available in the 6-Pin TSOT package. Th Is package is ideal where space is a critical item.
