Overview
The MAX9052BEUA+T is a micropower, single-supply analog comparator integrated with a precision voltage reference. It operates on a supply voltage range of 2.7V to 5.5V and consumes only 55µA of quiescent current. The device features dual comparators with rail-to-rail inputs and outputs, capable of sinking or sourcing up to 8mA. It includes an internal ±3mV hysteresis mechanism and offers a fixed 2.500V reference output. Propagation delay is specified at 400ns typical, with input offset voltage typically at 1mV.
Feature Summary
- Integrates dual comparators with a precision voltage reference in a compact package
- Features rail-to-rail input and output stages for wide signal compatibility
- Includes internal hysteresis to ensure clean switching with slow-moving signals
- Minimizes supply current surges during transitions to prevent power glitches
Applications
- Precision battery management systems
- Window comparator circuits
- Infrared (IR) receivers
- Level translators
- Digital line receivers
Procurement Notes
Verify the specific suffix 'BEUA' corresponds to the B-grade reference accuracy and µMAX package when ordering. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the supply voltage range aligns with the 2.7V minimum requirement for this specific variant. Check for any recent product change notices regarding pinout or electrical characteristics updates.
Selection Notes
Select this component when dual comparison functionality is required alongside a stable voltage reference in space-constrained designs. The low supply current makes it suitable for battery-operated applications. Consider the B-grade accuracy specifications if tighter initial accuracy tolerances are not critical. Evaluate the propagation delay against system timing requirements before finalizing the design.
Part Context
This part belongs to the MAX9038–MAX9053 family of micropower comparators and references. It shares architectural similarities with other members like the MAX9050 and MAX9051 but differs in channel count and reference voltage. The family is designed for low-voltage, single-supply operation, targeting portable electronics and industrial control applications requiring high precision and low power consumption.
Replacement Considerations
