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.
