MAX40009AUT+T

Overview

The MAX40009AUT+T is a single-channel analog comparator from Analog Devices, packaged in a 6-pin SOT-23 format. It operates on a supply voltage range of 1.7V to 5.5V with a typical quiescent current of 12μA and a maximum of 17μA across the -40°C to +125°C temperature range. The device features rail-to-rail inputs, a push-pull output stage, and an active-low shutdown input that reduces current to 1μA. Electrical specifications include a typical propagation delay of 220ns, an input offset voltage of ±0.5mV, and integrated hysteresis.

Feature Summary

• Push-pull output stage designed to limit supply-current surges during switching, virtually eliminating supply glitches.
• Integrated internal hysteresis ensures clean output switching even with slow-moving input signals.
• Rail-to-rail input common-mode range extends beyond both supply rails for flexible signal interfacing.
• Active-low shutdown pin significantly reduces quiescent current consumption when disabled.

Applications

• Mobile communications systems
• Portable and battery-powered devices
• Window comparators and threshold detectors
• Logic level translators
• IR receivers

Procurement Notes

Verify the specific suffix 'AUT' confirms the SOT-23 package variant rather than the WLP option. Confirm RoHS compliance status via the '+' designation in official documentation. Ensure the active-low shutdown logic aligns with system control requirements before integration.

Selection Notes

Select this component over the MAX40008 when a push-pull output is required instead of open-drain. Verify that the 12μA typical supply current meets low-power constraints. Check if the 220ns propagation delay satisfies timing requirements compared to faster alternatives.

Part Context

This part belongs to the MAX40008/MAX40009 family of micro-power comparators. It shares core electrical characteristics with the MAX40008 but differs in output topology. The series is designed for low-voltage applications ranging from 1.8V to 5V nominal supplies.

Replacement Considerations

MAX40008AUT+T serves as a functional substitute with identical electrical parameters except for the open-drain output configuration.
