Dual 280ps High-Speed Comparator, Ultra-Low Dispersion with LVDS Outputs

Industry's Fastest Dual LVDS Comparator with 280ps Propagation Delay and Overdrive Dispersion of 25ps

Product Details

The MAX40027 is a single-supply, dual high-speed comparator with a typical propagation delay of 280ps. The overdrive dispersion is extremely low (25ps, typ.), making these comparators ideal for time-of-flight, distance-measurement applications.

The input common mode range of 1.5V to VDD + 0.1V is compatible with the output swings of several widely used high-speed trans-impedance amplifiers, such as the MAX40658, MAX40660, and MAX40661.

The output stage is LVDS (Low-Voltage Differential Signaling), which helps to minimize power dissipation and interfaces directly with many FPGAs and CPUs. Complementary outputs help in suppression of common-mode noise on each output line.

The MAX40027 is offered in a tiny, space-saving, 3mm x 2mm, 12-pin TDFN package with side-wettable flanks, and meets AEC-Q100 automotive qualification requirements. The MAX40027 operates over the -40°C to +125°C temperature range and runs from a 2.7V to 3.6V supply voltage.

Description

The MAX40027 evaluation kit (EV kit) is a fully assembled electrical demonstration kit that provides a proven design to evaluate the MAX40027 ultra-low 280ps propagation delay, ultra-low dispersion dual comparator. The board provides layout options that allow the input termination to be easily modified for alternative input terminations. The comparator outputs are designed to drive low voltage differential signal outputs (LVDS). The LVDS outputs help minimize power dissipation and interfaces directly with high speed interconnect devices, FPGAs and CPUs. The MAX40027 comparator is ideal for time of flight distance measurement applications.

This evaluation kit demonstrates the MAX40027.
