LMH7220 High Speed Comparator with LVDS Output
September 2006
LMH7220
High Speed Comparator with LVDS Output
General 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 100鈩?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 TSOT package. ThIs
package is ideal where space is a critical item.
