Overview
The MAX9043BEUB 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 from 2.5V to 5.5V and consumes only 55µA of 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 for clean switching and offers a 2.048V reference output with B-grade accuracy.
Feature Summary
- Dual comparators with integrated precision voltage reference
- Rail-to-rail input and output stages
- Internal ±3mV hysteresis for noise immunity
- Low supply current consumption
Applications
- Precision battery management systems
- Window comparator circuits
- IR receivers
- Level translators
- Digital line receivers
Procurement Notes
Verify the specific suffix 'B' indicates the B grade (1% initial accuracy) when sourcing. Confirm the package type matches the required PCB layout. Check for lead-free/RoHS compliance status if environmental regulations apply. Ensure the operating temperature range meets system requirements.
Selection Notes
Select this component for applications requiring low power consumption in battery-operated devices. Choose the B grade if higher initial accuracy is not critical but cost efficiency is desired. Consider the 10-pin uMAX package constraints during PCB design. Verify that the 2.048V reference voltage aligns with downstream circuit requirements.
Part Context
This part belongs to the MAX9038–MAX9043 family of micropower, single-supply comparator and precision reference ICs. These devices are designed for low-voltage operation and are suitable for portable electronics. The family includes variants with single or dual comparators and different reference voltages.
Replacement Considerations
Direct substitutes include other parts within the MAX9038-MAX9053 series with matching pin counts and reference voltages. Verify compatibility regarding package dimensions and electrical characteristics before substitution.
