Overview
The MAX9140AAUK+T is a single-channel, high-speed analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 5.5V and features rail-to-rail input voltage capability extending beyond the power-supply rails. The device provides CMOS, push-pull, and TTL-compatible outputs that pull within 0.3V of either supply rail without external pullup circuitry. Key electrical specifications include a maximum propagation delay of 40ns at 10mV overdrive, a typical supply current of 360µA at 5V, and an internal hysteresis of 1.5mV. It is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Rail-to-rail input voltage range extends beyond both power-supply rails for flexible signal interfacing.
- CMOS/TTL-compatible outputs with low saturation voltage eliminate the need for external pullup resistors.
- Internal fixed hysteresis ensures clean output switching and prevents oscillation caused by noise or slow-moving signals.
- Continuous short-circuit protection allows all pins to tolerate fault conditions to either supply rail.
Applications
- Line receivers
- Threshold detectors and discriminators
- Zero-crossing detectors
- Sampling circuits
Procurement Notes
Verify the specific suffix 'AA' indicates the A-grade temperature rating (-40°C to +125°C) rather than the standard E-grade. Confirm the '+T' designation corresponds to tape-and-reel packaging. Ensure the ordering part number matches the exact pinout and package dimensions required for the PCB footprint.
Selection Notes
Select this component when a single-channel comparator with rail-to-rail inputs is required for 3V or 5V systems. It serves as a direct upgrade to industry-standard comparators like the MAX941/MAX942 series, offering higher speed and lower power consumption. Consider the MAX9141 if latch enable or shutdown functionality is needed.
Part Context
This device belongs to the MAX9140 family of high-speed, low-power comparators optimized for portable equipment. The family includes dual (MAX9142) and quad (MAX9144) variants, as well as the feature-rich MAX9141. These devices are designed to replace older generations of comparators while maintaining compatibility with standard logic families.
Replacement Considerations
Public confirmed substitute part numbers: MAX9140EUK+T, MAX9140EXK+T, MAX9140AAXK+T.
