Overview
The MAX40025CAWT+ is a single-supply, high-speed comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 3.6V and features a typical propagation delay of 280ps with an overdrive dispersion of 25ps. The device utilizes LVDS outputs for power efficiency and noise suppression. It is housed in a 6-bump WLP package measuring 1.218mm x 0.818mm. The input common-mode range extends from 1.5V to VDD + 0.1V, and it functions across a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low overdrive dispersion ensures precise timing accuracy for distance measurement applications.
- LVDS output stage minimizes power dissipation while providing differential signaling compatible with FPGAs and CPUs.
- Input common-mode range extends beyond the positive supply rail to interface directly with transimpedance amplifiers.
Applications
- Distance sensing in LIDAR, RADAR, and SONAR systems
- Time-of-flight sensors
- High-speed triggering in oscilloscopes
- Threshold detectors
Procurement Notes
Verify the specific suffix 'CAWT+' corresponds to the 6-WLP package variant without internal hysteresis. Confirm that the component meets RoHS compliance standards as indicated by the '+' designation. Ensure the ordering quantity aligns with tape-and-reel packaging requirements specified by the manufacturer.
Selection Notes
Select this part when ultra-low dispersion is critical for time-of-flight measurements. The absence of internal hysteresis makes it suitable for detecting very small, fast-changing signals where external hysteresis is not desired. Ensure the application requires LVDS outputs and operates within the 2.7V to 3.6V supply range.
Part Context
This component belongs to the MAX40025/MAX40026 family of high-speed comparators designed for automotive and communication applications. It shares performance characteristics with the MAX40026 but differs in package type and hysteresis configuration. The family is AEC-Q100 qualified, ensuring reliability in demanding environments.
Replacement Considerations
The MAX40025AAWT+ serves as a direct substitute if internal 2.5mV hysteresis is required instead of none. For TDFN-8 package variants, the MAX40026ATA/VY+ offers similar performance with 1.5mV internal hysteresis. Verify pin compatibility and thermal requirements when substituting.
FAQ
Does the MAX40025CAWT+ have internal hysteresis?
No, the MAX40025C variant is optimized for detecting very small, fast-changing signals and does not include internal hysteresis.
What is the maximum input common-mode voltage?
The input common-mode range extends up to VDD + 0.1V, allowing compatibility with high-speed transimpedance amplifier outputs.
