Overview
The MAX9043BEUB-T is a micropower, single-supply integrated circuit featuring dual comparators and a precision voltage reference. It operates from a 2.5V to 5.5V supply with a typical supply current of 55µA. The device includes a 2.048V reference output with B-grade accuracy (1% initial accuracy, 100ppm/°C tempco). Comparators offer rail-to-rail inputs and outputs, ±3mV internal hysteresis, and a propagation delay of 400ns. It is housed in a 10-pin µMAX package.
Feature Summary
- Dual comparators with rail-to-rail input and push-pull output stages
- Integrated precision voltage reference with curvature-correction circuit
- Internal hysteresis for clean switching on slow-moving signals
- Low supply current consumption suitable for battery-operated systems
Applications
- Precision Battery Management
- Window Comparators
- IR Receivers
- Level Translators
- Digital Line Receivers
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'B' grade designation aligns with required initial accuracy and temperature coefficient specifications. Ensure the 10-pin µMAX package footprint matches the target PCB design constraints.
Selection Notes
Select this component when dual comparator functionality is required alongside a stable voltage reference in a compact form factor. The low quiescent current makes it appropriate for portable applications. Verify that the 2.048V reference voltage meets system requirements compared to alternative 1.23V or 2.500V options within the family.
Part Context
This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparator and reference ICs. The series offers various combinations of single/dual comparators and different reference voltages across UCSP, SOT23, SO, and µMAX packages.
