Dual 700 ps High Speed Comparator with RSPECL Outputs

Dual 700 ps High Speed Comparator with RSPECL Outputs - LMH7322
 

Description

The LMH7322 is a dual comparator with 700 ps propagation delay, low dispersion of 75 ps and an input voltage range that extends from VCC-1.5V to VEE. The devices can be operated from a wide supply voltage range of 2.7V to 12V. The adjustable hysteresis adds flexibility and prevents oscillations. Both the outputs and latch inputs of the LMH7322 are RSPECL compatible. When used in combination with a VCCO supply voltage of 2.5V the outputs have LVDS compatible levels.

The LMH7322 is available in a 24-pin WQFN package.
