Analog Devices Inc. MAX40027 Dual High-Speed Comparators

Analog Devices Inc. MAX40027 Dual High-Speed Comparators have 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 suppress 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.
