MAX9053AEUB+

Overview

The MAX9053AEUB+ is a dual-channel micropower analog comparator with an integrated precision voltage reference, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2.7V to 5.5V and consumes only 55µA of quiescent current. The device features rail-to-rail inputs and outputs, with a common-mode input range extending 250mV beyond the supply rails. It includes internal hysteresis of ±3mV and offers a propagation delay of 400ns. The A-grade reference provides 2.500V output with 0.4% initial accuracy and a temperature coefficient of 6ppm/°C.

Feature Summary

• Integrates dual comparators with a precision voltage reference in a compact package
• Features rail-to-rail inputs and push-pull outputs capable of sourcing and sinking up to 8mA
• Includes internal ±3mV hysteresis for clean switching with slow-moving signals
• Utilizes proprietary curvature-correction circuitry for high-accuracy reference performance

Applications

• Precision battery management systems
• Window comparator circuits
• Infrared (IR) receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify the specific suffix 'EUB+' corresponds to the 10-pin µMAX package and lead-free/RoHS compliance status as indicated by the '+' designation. Confirm that the 'A' grade denotes the higher precision variant with 0.4% initial accuracy and 6ppm/°C tempco, distinct from the B grade. Ensure the operating environment stays within the -40°C to +85°C temperature range specified for this part number.

Selection Notes

Select this component when low power consumption is critical alongside precise voltage monitoring. The dual comparator configuration allows for complex threshold detection using a single reference source. The rail-to-rail input capability ensures compatibility with signals near the supply rails. Consider the 10-pin µMAX package constraints if board space is limited, noting the thermal derating requirements for continuous operation.

Part Context

This device belongs to the MAX9038–MAX9053 family of micropower, single-supply comparator and reference ICs. It shares architectural similarities with the MAX9052 but differs in package type and output stage characteristics. The MAX9053 specifically integrates two comparators and one reference, distinguishing it from single-comparator variants like the MAX9051. It is designed for battery-operated systems requiring both signal comparison and stable voltage referencing.
