Overview
The MAX9140EXK+T is a single-supply, high-speed analog comparator from Analog Devices. It operates on a supply voltage range of 2.7V to 5.5V with a typical propagation delay of 40ns at 10mV overdrive. The device draws 150µA per comparator at 3V and features rail-to-rail input voltage capability extending beyond the power rails. It includes internal hysteresis for clean switching and outputs that swing within 300mV of either supply rail without external pullup circuitry.
Feature Summary
- Rail-to-rail input voltage range extending beyond both power-supply rails
- Internal hysteresis ensures clean output switching with slow-moving signals
- Outputs pull to within 300mV of supply rails without external pullup circuitry
- Continuous short-circuit fault tolerance on all input and output pins
Applications
- Line Receivers
- Threshold Detectors/Discriminators
- Zero-Crossing Detectors
- Sampling Circuits
Procurement Notes
Verify the specific suffix 'EXK' corresponds to the SC70 package and E-grade temperature rating (-40°C to +85°C) as listed in the official ordering information. Confirm RoHS compliance status based on the '+' designation in the part number. Ensure the component matches the single-channel configuration distinct from the dual or quad variants.
Selection Notes
Select this component when a single-channel comparator is required for 3V or 5V systems. It serves as a lower-power and higher-speed upgrade to industry-standard comparators like the MAX941. Choose this part if rail-to-rail inputs and direct interface to CMOS/TTL logic are necessary without external pullup resistors.
Part Context
This device belongs to the MAX914x family of single-supply comparators optimized for portable equipment. The MAX9140 is the single-channel version, while the MAX9141 adds latch/shutdown functions, and the MAX9142/MAX9144 provide dual/quad channels. All share similar electrical characteristics regarding speed and power consumption.
Replacement Considerations
The datasheet identifies the MAX9140 as a direct replacement for the MAX941, MAX942, and MAX944 comparators.
