Overview
The MAX9140AAXK/V+T is a single-channel, high-speed analog comparator from the MAX9140 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 5.5V with a typical supply current of 360µA at 5V. The device features a propagation delay of 40ns and an input offset voltage of up to 6mV. It utilizes a 5-pin SC70 surface-mount package and supports CMOS/TTL logic outputs. This specific variant is AEC-Q100 qualified for automotive applications.
Feature Summary
- Rail-to-rail input voltage range extending beyond power-supply rails
- Internal hysteresis for clean output switching without external resistors
- CMOS and TTL-compatible outputs pulling within 300mV of supply rails
- 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 exact suffix 'V' in the ordering code against official documentation, as it may indicate specific packaging or qualification variations. Confirm availability status through authorized distributors, as this component may be subject to limited stock or discontinuation notices. Ensure the procurement channel provides valid traceability for the AEC-Q100 qualification if required for automotive integration.
Selection Notes
Select this comparator for systems requiring low-power operation with rail-to-rail inputs in compact SC70 packages. It serves as a direct upgrade to older industry-standard comparators like the MAX941/MAX942 series. Consider the fixed internal hysteresis when designing circuits that require noise immunity without adding external feedback components.
Part Context
This part belongs to the MAX9140/MAX9141/MAX9142/MAX9144 family of 40ns, low-power, 3V/5V, rail-to-rail single-supply comparators. The MAX9140 specifically denotes the single-channel version available in 5-pin SC70 and SOT23 packages. The 'AA' grade indicates an extended temperature range capability compared to standard E-grade devices.

FAQ
Does the MAX9140AAXK/V+T include a shutdown function?
No, the shutdown function is exclusive to the MAX9141 variant. The MAX9140 does not have a SHDN pin.
What is the maximum operating temperature for the AA grade?
The AA grade devices are specified over an operating temperature range of -40°C to +125°C.
