DESCRIPTION
The LMH7324 is a quad comparator with 700 ps
propagation delay and low dispersion of 20 ps for a
supply voltage of 5V. The input voltage range
extends 200 mV below the negative supply. This
enables the LMH7324 to ground sense even when
operating on a single power supply. The device
operates from a wide supply voltage range from 5V to
12V, which allows for a wide input voltage range.
However, if a wide input voltage range is not
required, operating from a single-ended 5V supply
results in a significant power savings, and less heat
dissipation.
The outputs of the LMH7324 are RSPECL compatible
and can also be configured to create LVDS levels.
The LMH7324 operates over the industrial
temperature range of −40°C to 125°C. The LMH7324
is available in a 32-Pin WQFN package.
