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.
