LMH7220

High Speed Comparator with LVDS Output

General Description

Features

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).

(V_S= 5V T_A= 25°C, Typical values unless otherwise speci-

fied)

■

The LMH7220 inputs have a voltage range that extends 200

mV below ground, allowing ground sensing applications. The

LMH7220 is available in both the 6-Pin TSOT and SC-70

packages. These packages are ideal where space is a critical

item.
