Supply Voltage 2.7V to 3.6V
39.4mW at 2.7V Supply
Power-Efficient LVDS Outputs
-40°C to +125°C Temperature Range
Automotive AEC-Q100 Qualified (TDFN-8 Version)

Internal 2.5mV Hysteresis: MAX40025A

Product Details

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 V_DD + 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.

View Detailed Evaluation Kit Information

The MAX40026 evaluation kit (EV kit) is a fully assembled electrical demonstration kit that provides a proven design to evaluate the MAX40026 ultra-low 280ps propagation delay, ultra-low dispersion comparator with 2mV hysteresis. 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, FPGA’s and CPU. The MAX40026 comparator is ideal for time of flight distance measurement applications.

This EV kit demonstrates the MAX40026ATA/VY+ in an 8-pin TDFN package.
