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

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

Please check latest availability status for a specific part variant.


The MAX40025 and MAX40026 are single-supply, high-speed comparators with a typical propagation delay of 280ps. The overdrive dispersion is extremely low (typical 25ps), 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.

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 MAX40025 is offered in a space-saving, tiny, 1.218mm x 0.818mm, 6-bump wafer-level package (WLP), while the MAX40026 is available in a 2mm x 2mm 8-pin TDFN package and meets AEC-Q100 automotive qualification requirements. The MAX40025/MAX40026 operate over -40°C to +125°C temperature range and run from a single supply voltage of 2.7V to 3.6V.
