MAX9043AEUB-T

Overview

The MAX9043AEUB-T is a dual-channel, micropower analog comparator with an integrated precision voltage reference. 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 fixed 2.048V output with A-grade accuracy of 0.4% initial accuracy and a temperature coefficient of 6ppm/°C.

Feature Summary

• Dual comparators with integrated precision voltage 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
• IR receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify the exact suffix against official documentation to confirm package type and grade. Confirm RoHS compliance status through manufacturer datasheets. Ensure the ordering code matches the required temperature range and electrical specifications before procurement.

Selection Notes

Select this component when dual independent comparison is required alongside a stable voltage reference in space-constrained designs. The low supply current makes it appropriate for portable applications. Verify that the 400ns propagation delay meets system timing requirements.

Part Context

This part belongs to the MAX9038–MAX9043 family of micropower comparators. These devices combine low-power operation with high-precision references in compact packages. The MAX9043 specifically offers two comparators and a 2.048V reference in a 10-pin uMAX or USOP package.

Replacement Considerations

Direct substitutes include other members of the MAX9038–MAX9043 series such as the MAX9042, provided pin compatibility and functional requirements align.
