MAX9053AEUB-T

Overview

The MAX9053AEUB-T is a micropower, single-supply analog comparator integrated with a precision voltage reference. It features dual comparators and one reference in a 10-pin μMAX package. The device operates from a supply voltage range of 2.7V to 5.5V. Supply current consumption is typically 60μA at 2.7V and 85μA at 5.5V. The internal reference provides a fixed output voltage of 2.500V with an initial accuracy of ±0.4% (A grade) and a temperature coefficient of 6ppm/°C typical. Comparator inputs feature rail-to-rail capability extending 250mV beyond the supply rails, with input bias current typically 1.0pA. Output stages are push-pull, capable of sinking and sourcing up to 8mA. Propagation delay is typically 400ns.

Feature Summary

• Integrates dual comparators with a precision voltage reference for space-constrained designs
• Features rail-to-rail inputs and outputs with extended common-mode voltage range
• Includes internal hysteresis to ensure clean switching on slow-moving signals
• Utilizes unique output stage design to minimize 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 'T' indicates tape-and-reel packaging configuration. Confirm the 'A' grade designation corresponds to the 0.4% initial accuracy and 6ppm/°C temperature coefficient specifications. Ensure the 'EUB' code matches the 10-lead μMAX package outline required for your PCB footprint. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency.

Selection Notes

Select this component when dual comparison functions are required alongside a stable voltage reference within a minimal footprint. The low quiescent current makes it suitable for battery-operated applications. Choose the A-grade variant if tight initial accuracy and low temperature drift are critical. Verify that the 2.7V minimum supply voltage aligns with your system's power rails.

Part Context

This part belongs to the MAX9038–MAX9053 family of micropower comparators with references. It shares architectural similarities with the MAX9052 but differs in package type and specific electrical characteristics. The family is designed for low-voltage, single-supply operation, offering various combinations of single or dual comparators with different reference voltages.
