MAX40027ATC/VY+T

Overview

The MAX40027ATC/VY+T is a dual high-speed comparator with a typical propagation delay of 280ps and ultra-low overdrive dispersion of 25ps. It operates on a single supply voltage ranging from 2.7V to 3.6V, consuming approximately 17mA per comparator at 3.3V. The device features LVDS outputs compatible with FPGAs and CPUs, an input common-mode range of 1.5V to VDD + 0.1V, and fixed internal hysteresis of 1.5mV. It is housed in a 12-pin SWTDFN-EP package measuring 3mm x 2mm and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Ultra-low overdrive dispersion ensures precise timing accuracy for distance measurement applications
• LVDS output stage minimizes power dissipation and provides direct interface compatibility with modern digital logic
• Automotive-grade reliability achieved through AEC-Q100 qualification and extended temperature operation
• Integrated protection circuitry safeguards the precision input stage against large differential input voltages

Applications

• Time-of-flight sensors for distance measurement
• Automotive Advanced Driver Assistance Systems (ADAS)
• High-speed triggering in oscilloscopes
• Threshold detectors and oscillators
• High-speed differential line receivers

Procurement Notes

Verify that the ordering suffix 'T' confirms tape-and-reel packaging and '/VY+' indicates automotive qualification with side-wettable flanks. Confirm RoHS compliance status via the '+' designation. Ensure the specific lot date code aligns with project requirements as manufacturing revisions may occur without functional changes. Cross-reference the datasheet revision number to validate electrical characteristics against current production samples.

Selection Notes

Select this component when sub-nanosecond timing jitter and minimal propagation delay variation are critical. The LVDS interface is suitable for high-speed data transmission to FPGAs or CPUs requiring low electromagnetic interference. Verify that the system supply voltage remains within the 2.7V to 3.6V range. Consider the 1.5mV internal hysteresis for noise immunity in environments with slow-moving signals.

Part Context

This part belongs to the MAX40027 family of high-speed comparators designed for precision timing applications.
