Overview
The MAX9042BEUA+T is a dual-channel micropower comparator with an integrated precision voltage reference, housed in an 8-pin µMAX package. It operates on a single supply from 2.5V to 5.5V and consumes only 55µA of quiescent current. The device features rail-to-rail inputs and outputs, ±3mV internal hysteresis, and a propagation delay of 400ns. The built-in reference provides a stable 2.048V output with B-grade accuracy.
Feature Summary
- Dual comparators with integrated 2.048V precision reference
- Rail-to-rail input and push-pull output stages
- Internal ±3mV hysteresis for clean switching
- Low power consumption suitable for battery systems
Applications
- Precision Battery Management
- Window Comparators
- Level Translators
Procurement Notes
Verify the specific suffix BEUA corresponds to the 8-pin µMAX package and B-grade reference accuracy. Confirm the component status as active or obsolete through official Analog Devices channels before procurement planning.
Selection Notes
Select this part when dual independent comparisons are required alongside a fixed voltage reference in space-constrained designs. The µMAX package offers thermal efficiency, while the low supply current supports extended battery life in portable applications.
Part Context
This component belongs to the MAX9038–MAX9043 family of micropower comparators. It shares architectural similarities with single-channel variants like the MAX9041 but integrates two comparator channels within the same compact footprint.
Replacement Considerations
The MAX9042AEUA+T serves as a direct functional replacement with A-grade reference accuracy. Other family members such as the MAX9042BESA share identical electrical characteristics but utilize an SOIC package.
