Overview
The MAX9053AEUB+T is a micropower, single-supply analog comparator integrated with a precision voltage reference. It features dual comparators and one reference within a 10-pin uMAX package. The device operates from a supply voltage range of 2.7V to 5.5V. Quiescent supply current is typically 60µA at 2.7V and 85µA at 5.5V. The internal reference provides a fixed output voltage of 2.500V. Comparator inputs support rail-to-rail operation with an input common-mode voltage range extending 250mV beyond the supply rails. Propagation delay is specified at 400ns with 100mV overdrive.
Feature Summary
- Integrates dual comparators with a precision voltage reference in a compact footprint
- Features rail-to-rail inputs and outputs for wide signal compatibility
- Includes internal hysteresis to ensure clean switching on slow-moving signals
- Utilizes a unique output stage design that 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 'EUB' corresponds to the 10-pin uMAX package configuration required for your board layout. Confirm the 'A' grade designation aligns with the necessary initial accuracy specifications for your application. Ensure the '+T' tape-and-reel packaging matches your automated assembly equipment capabilities before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel comparison function is required alongside a stable voltage reference source. The low quiescent current makes it suitable for battery-operated applications where power conservation is critical. Verify that the 2.7V minimum supply voltage meets your system's lowest operating conditions. Consider the 10-pin package size constraints against available PCB real estate.
Part Context
This part belongs to the MAX9038–MAX9053 family of micropower comparators with precision references. The MAX9053 specifically combines two comparators with a 2.500V reference. It shares architectural similarities with other members like the MAX9052 but differs in pinout and package options. The family is designed for low-voltage, single-supply operation in portable electronics.
Replacement Considerations
Direct substitutes include the MAX9053BEUB+T, which offers B-grade reference accuracy instead of A-grade. Other family members such as the MAX9052 share similar electrical characteristics but differ in package type or channel count.
