Overview
The MAX9052BEUA+ is a micropower, single-supply analog comparator integrated with a precision voltage reference. It features dual comparators and one reference in an 8-pin uMAX package. Operating from a 2.7V to 5.5V supply, it consumes 55µA typical quiescent current. The device provides rail-to-rail inputs and outputs, with a propagation delay of 400ns. The internal reference outputs 2.500V with B-grade accuracy (1% initial accuracy, 100ppm/°C tempco).
Feature Summary
- Integrates dual comparators with a precision voltage reference in a compact surface-mount package.
- Features rail-to-rail input and output stages capable of sinking and sourcing up to 8mA.
- Includes internal hysteresis to ensure clean switching for slow-moving signals.
- Designed for low-voltage operation with minimal supply current surges during transitions.
Applications
- Precision battery management systems
- Window comparator circuits
- IR receivers
- Level translators
Procurement Notes
Verify the specific suffix 'BEUA+' corresponds to the B-grade reference accuracy and 8-pin uMAX package configuration. Confirm that the operating temperature range meets the -40°C to +85°C requirement for the intended environment. Ensure the supply voltage remains within the 2.7V to 5.5V limits to maintain specified performance characteristics.
Selection Notes
Select this component when dual comparison functions are required alongside a stable 2.5V reference source. It is suitable for space-constrained designs due to the small uMAX footprint. Consider the 400ns propagation delay for timing-sensitive applications. Verify if the B-grade reference accuracy is sufficient or if the A-grade variant is needed for tighter tolerances.
Part Context
This part belongs to the MAX9038–MAX9053 family of micropower comparators with references. It shares architectural similarities with the MAX9042 series but differs in reference voltage and package options. The MAX9052 specifically targets applications requiring a 2.5V reference output compared to the 2.048V found in other family members.
Replacement Considerations
Direct substitutes include MAX9052AEUA+ for higher reference accuracy. Other family members like MAX9042BEUA+ offer similar functionality but with a different reference voltage output.
