DESCRIPTION

The LMH7220 is a high speed, low power comparator

with an operating supply voltage range of 2.7V to

12V. The LMH7220 has a differential, LVDS output,

driving 325 mV 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 mA at 5V (load current excluded).

The LMH7220 inputs have a voltage range that

extends 200 mV below ground, allowing ground

sensing applications. The LMH7220 is available in the

6-Pin SOT package. This package is ideal where

space is a critical item.
