Overview
The MAX40025CAWT+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. The device provides LVDS outputs compatible with FPGAs and CPUs, an input common-mode range from 1.5V to VDD + 0.1V, and no internal hysteresis. It functions within a -40°C to +125°C temperature range in a compact 6-bump WLP package.
Feature Summary
- Ultra-low overdrive dispersion ensures precise timing for distance measurement applications
- LVDS output stage minimizes power dissipation and interfaces directly with digital logic
- Input common-mode range extends beyond the positive rail for TIA compatibility
Applications
- Distance sensing in LIDAR, RADAR, and SONAR systems
- Time-of-flight sensors
- High-speed differential line receivers
- Threshold detectors
- Oscilloscope triggering
Procurement Notes
Verify the specific suffix 'C' indicates zero internal hysteresis, distinguishing it from the 'A' variant which includes fixed hysteresis. Confirm the 'WLT' or similar tape-and-reel designation matches the required packaging format. Ensure the component meets RoHS compliance standards as indicated by the '+' suffix. Cross-reference the exact part number against the manufacturer's latest ordering information to confirm availability and production status.
Selection Notes
Select this component when minimal propagation delay variation across different overdrive voltages is critical. The absence of internal hysteresis makes it suitable for detecting very small, fast-changing signals without added threshold offsets. Ensure the application can accommodate the 100Ω external termination resistor required for the LVDS outputs. Verify that the 6-WLP package dimensions fit the available PCB space constraints.
Part Context
This device belongs to the MAX40025/MAX40026 family of high-speed comparators designed for time-of-flight measurements. While the MAX40026 utilizes an 8-pin TDFN package and holds AEC-Q100 automotive qualification, the MAX40025CAWT+T uses a 6-bump WLP package. Both share identical electrical performance characteristics regarding speed and dispersion.
Replacement Considerations
The MAX40025AAWT+ serves as a direct functional substitute but includes 2.5mV of internal hysteresis. The MAX40026 offers equivalent performance in an 8-TDFN package with 1.5mV hysteresis and automotive qualification.
