MAX9052AESA-T

Overview

The MAX9052AESA-T is a micropower, single-supply analog comparator and precision voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It features dual comparators with rail-to-rail inputs and outputs, alongside a fixed 2.5V precision reference. The device operates on a single supply voltage ranging from 2.7V to 5.5V. Key electrical parameters include a typical propagation delay of 400ns, a quiescent supply current of 55µA at 2.7V, and an input offset voltage typically specified at 0.5mV.

Feature Summary

• Integrates dual low-power comparators with a high-precision voltage reference in a single package
• Features rail-to-rail input and output stages capable of sinking and sourcing up to 8mA
• Includes internal hysteresis to ensure clean output switching for slow-moving signals
• Utilizes a unique output stage design that minimizes supply current surges during switching

Applications

• Precision battery management systems
• Window comparator circuits
• Infrared (IR) receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the A-grade designation corresponds to the required initial accuracy and temperature coefficient specifications. Ensure the SOIC-8 package variant matches your board layout requirements. Cross-reference the datasheet revision date to confirm compatibility with your design constraints.

Selection Notes

Select this component for applications requiring dual comparison functions combined with a stable voltage reference in a compact form factor. The low supply current makes it suitable for battery-operated devices. Consider the rail-to-rail input range if signal levels approach the supply rails. Verify that the 400ns propagation delay meets the timing requirements of your digital interface.

Part Context

This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparator and reference ICs. The MAX9052 specifically provides dual comparators and a 2.5V reference. It is designed for low-voltage, single-supply operation, offering a cost-effective solution for integrating monitoring and reference functions into space-constrained electronic designs.

Replacement Considerations

Direct substitutes within the same family include the MAX9053, which shares identical pinout and functionality but may differ in grading or packaging options. Other variants like the MAX9042 offer similar dual-comparator performance with a different reference voltage.
