Overview
The MAX40026ATA+T is a single-supply, high-speed comparator featuring LVDS outputs and an 8-pin TDFN package. It operates on a 2.7V to 3.6V supply with a typical propagation delay of 280ps and low overdrive dispersion of 25ps. The device includes internal 1.5mV hysteresis and supports an input common-mode range from 1.5V to VDD + 0.1V. It meets AEC-Q100 automotive qualification standards and functions within a -40°C to +125°C temperature range.
Feature Summary
- Ultra-low overdrive dispersion for precise time-of-flight distance measurement applications
- LVDS output stage minimizes power dissipation and interfaces directly with FPGAs and CPUs
- Internal fixed 1.5mV hysteresis improves noise immunity without external components
- AEC-Q100 qualified automotive-grade reliability in a compact 2mm x 2mm TDFN package
Applications
- Distance sensing in LIDAR, RADAR, and SONAR systems
- Time-of-flight sensors
- High-speed differential line receivers
- High-speed triggering in oscilloscopes
- Automotive applications
Procurement Notes
Verify the specific suffix 'ATA' corresponds to the tape-and-reel packaging format and the 8-TDFN footprint. Confirm that the component meets RoHS compliance requirements as indicated by the '+' designation. Ensure the ordering information matches the required temperature range and hysteresis specifications before finalizing procurement.
Selection Notes
Select this part when low overdrive dispersion is critical for accurate timing measurements. The integrated LVDS outputs simplify interfacing with digital logic while reducing EMI. The built-in hysteresis eliminates the need for external feedback networks, saving board space. Verify compatibility with the system's supply voltage and input signal levels against the specified common-mode range.
Part Context
This component belongs to the MAX40025/MAX40026 family of high-speed comparators designed for demanding timing applications. While the MAX40025 utilizes a WLP package, the MAX40026 variant provides an automotive-qualified TDFN option. Both share identical electrical performance characteristics regarding speed and dispersion.
Replacement Considerations
The MAX40025AAWT+ serves as a functional alternative but utilizes a different 6-WLP package and features 2.5mV hysteresis instead of 1.5mV. Direct pin-to-pin replacement requires verifying package compatibility and adjusting for the hysteresis difference.
