Overview
The MAX40025AAWT+T is a single-supply, high-speed comparator featuring a typical propagation delay of 280ps and ultra-low overdrive dispersion of 25ps. It operates on a 2.7V to 3.6V supply with a quiescent current of 17mA to 23mA. The device utilizes LVDS outputs for power efficiency and direct FPGA interfacing. It includes internal hysteresis of 2.5mV and functions within a -40°C to +125°C temperature range.
Feature Summary
- Ultra-low overdrive dispersion ensures precise timing accuracy for distance measurement applications
- LVDS output stage minimizes power dissipation while suppressing common-mode noise
- Integrated input protection circuitry safeguards against large differential input voltages
- Fixed internal hysteresis improves signal detection stability in noisy environments
Applications
- Distance sensing in LIDAR, RADAR, and SONAR systems
- Time-of-flight sensors
- High-speed triggering in oscilloscopes
- Threshold detectors
- Automotive applications
Procurement Notes
Verify the specific suffix 'A' confirms the inclusion of 2.5mV internal hysteresis, distinguishing it from the non-hysteretic variant. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure compatibility with the 6-WLP package dimensions and thermal requirements during procurement planning.
Selection Notes
Select this component when low jitter and minimal propagation delay variation are critical. The fixed 2.5mV hysteresis eliminates the need for external feedback components. Verify that the 2.7V to 3.6V supply range aligns with system power rails and that LVDS signaling matches downstream receiver logic levels.
Part Context
This part belongs to the MAX40025/MAX40026 family of high-speed comparators designed for time-of-flight measurements. It shares core electrical characteristics with the MAX40025C but differs by including internal hysteresis. The WLP package provides a space-saving solution compared to larger TDFN alternatives.
Replacement Considerations
MAX40025CAWT+T serves as a substitute without internal hysteresis.
