MAX9051AEUT

Overview

The MAX9051AEUT is a micropower, single-supply analog comparator manufactured by Analog Devices Inc./Maxim Integrated. It features an integrated precision voltage reference and operates within a supply voltage range of 2.7 V to 5.5 V. The device offers a propagation delay of 450 ns and a quiescent current of 60 µA per channel. It utilizes a UCSP-6 surface-mount package and supports an open-drain output configuration with a maximum sink current of 8 mA. The input offset voltage is specified at 7 mV, ensuring reliable threshold detection in low-power applications.

Feature Summary

• Integrates a precision internal voltage reference for simplified circuit design
• Operates on a single power supply ranging from 2.7 V to 5.5 V
• Features ultra-low quiescent current consumption suitable for battery-powered systems
• Provides open-drain output capability for flexible logic interfacing

Applications

• Battery-operated portable electronics
• Threshold detection circuits
• Voltage monitoring systems
• Low-power signal conditioning

Procurement Notes

Verify the specific suffix 'EUT' against official manufacturer documentation to confirm the UCSP-6 package type and tape-and-reel shipping format. Ensure compatibility with RoHS directives if required for your region. Confirm availability status as this component may be subject to limited supply or end-of-life restrictions depending on the current production cycle.

Selection Notes

Select this component when system design requires minimal power consumption alongside precise voltage comparison. The integrated reference eliminates external resistor networks, reducing board space. Verify that the 450 ns propagation delay meets the timing requirements of the target application. Ensure the open-drain output aligns with the downstream logic level requirements.

Part Context

This part belongs to the MAX905x series of micropower comparators designed for energy-efficient applications. It shares functional similarities with other members like the MAX9051AESA but differs in packaging and reel specifications. The series is characterized by its ability to operate at low voltages while maintaining accuracy through internal reference integration.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the MAX9051AESA for pin-compatible alternatives. Verify that any substitute maintains the same UCSP-6 footprint and electrical characteristics, specifically the 60 µA quiescent current and 450 ns delay.
