Overview
The MAX9052AEUA is a micropower, single-supply analog comparator integrated with a precision voltage reference. It features dual comparators and one reference consuming only 55µA of supply current. The device operates from a 2.7V to 5.5V supply. Comparator inputs are rail-to-rail with a common-mode range extending 250mV beyond the rails. The internal reference provides a fixed 2.500V output. Propagation delay is 400ns typical. The package is an 8-pin µMAX.
Feature Summary
- Dual comparators combined with a precision voltage reference in a compact package
- Rail-to-rail input and output stages for maximum dynamic range
- Internal hysteresis ensures clean switching on slow-moving signals
- Unique output stage design minimizes supply current surges during transitions
Applications
- Precision battery management systems
- Window comparator circuits
- IR receivers
- Level translators
- Digital line receivers
Procurement Notes
Verify the specific suffix 'EUA' corresponds to the 8-pin µMAX package configuration. Confirm the 'A' grade designation indicates the required initial accuracy specifications. Check the manufacturer's official documentation for the most current production status and lead time information before finalizing procurement plans.
Selection Notes
Select this component when dual comparison functions are required alongside a stable voltage reference within a limited footprint. The low quiescent current makes it suitable for battery-operated applications. Ensure the 2.7V minimum supply voltage aligns with the system power budget. Verify that the 400ns propagation delay meets the timing requirements of the target application.
Part Context
This part belongs to the MAX9038–MAX9053 family of micropower comparators with integrated references. These devices are designed for low-voltage, single-supply operation. The family offers various configurations of single or dual comparators with different reference voltages and packaging options to suit diverse space-constrained electronic designs.
Replacement Considerations
The MAX9052BEUA serves as a lower-accuracy alternative within the same series. Both share identical pinouts and functional characteristics but differ in reference initial accuracy and temperature coefficient specifications.
