MAX9053AEUB

Overview

The MAX9053AEUB is a dual-channel micropower analog comparator with an integrated precision voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.7V to 5.5V and consumes only 55µA of quiescent supply 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 built-in voltage reference provides a stable output of 2.500V with A-grade initial accuracy of 0.4% 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 outputs with extended common-mode range
• Includes internal hysteresis for clean switching on slow-moving signals
• Utilizes unique output stage design to minimize supply current surges

Applications

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

Procurement Notes

Verify the specific ordering suffix 'AEUB' against the manufacturer's official documentation to confirm the exact pinout, package type, and grade specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before procurement.

Selection Notes

Select this component when a low-power solution requiring both signal comparison and a precise voltage reference is needed. It is suitable for battery-operated applications due to its minimal supply current consumption. Consider the dual-channel configuration if multiple comparison functions are required within a single footprint.

Part Context

This part belongs to the MAX9038–MAX9043 and MAX9050–MAX9053 family of micropower, single-supply comparators combined with precision voltage references. These devices are designed for low-voltage operation, making them ideal for portable electronics and systems requiring high efficiency.

Replacement Considerations

Direct substitutes within the same family include the MAX9053BEUB for B-grade specifications. Other variants like MAX9043AEUB offer similar functionality but with a different reference voltage output.
