Overview
The MAX9041BEUT+T is a micropower, single-supply analog comparator integrated with a precision voltage reference. It operates within a supply voltage range of 2.5V to 5.5V and consumes only 40μA of quiescent supply current. The device features rail-to-rail inputs and outputs, with an input common-mode voltage range extending 250mV beyond the supply rails. It provides a fixed 2.048V reference output and includes internal ±3mV hysteresis for clean switching. The propagation delay is typically 400ns at 2.7V supply.
Feature Summary
- Integrates a low-power comparator with a precision voltage reference in a compact SOT-23 package
- Features rail-to-rail inputs and outputs with extended common-mode voltage range
- Includes internal hysteresis to ensure stable output switching with slow-moving signals
- Unique output stage design minimizes supply current surges during switching
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 when sourcing. Confirm the B grade designation corresponds to the required initial accuracy and temperature coefficient specifications for your application. Ensure the SOT-23 footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this component when a single-supply operation between 2.5V and 5.5V is required alongside a precise voltage reference. It is suitable for battery-operated systems due to its low 40μA supply current. Choose this part over dual-channel variants if only one comparator channel is needed. Consider the B grade specifications for initial accuracy and temperature drift requirements.
Part Context
This device belongs to the MAX9038–MAX9043 family of micropower comparators with precision references. It shares architectural similarities with other members like the MAX9040 and MAX9042 but differs in pin count and reference voltage configuration. The MAX9041 specifically offers a single comparator with a 2.048V reference in a 6-pin SOT-23 package.
Replacement Considerations
The MAX9041AEUT+T is available as an A grade alternative with higher initial accuracy. Other family members such as the MAX9040 or MAX9042 may serve as functional substitutes depending on pin compatibility and reference voltage needs.
