Overview
The MAX9041BEUT-T is a micropower, single-supply comparator integrated with a precision voltage reference. It operates on a 2.5V to 5.5V supply and consumes 40μA of quiescent current. The device features rail-to-rail inputs and outputs, with an input common-mode range extending 250mV beyond the rails. It provides a fixed 2.048V reference output and includes internal ±3mV hysteresis for clean switching. The propagation delay is 400ns, and the output stage can sink or source up to 8mA.
Feature Summary
- Integrates a low-power comparator with a precision voltage reference in a compact package
- Features rail-to-rail inputs and outputs with extended common-mode voltage range
- Includes internal hysteresis to ensure stable switching with slow-moving signals
- Output driver design 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 'T' indicates tape-and-reel packaging when sourcing. Confirm that the component corresponds to the B grade specifications regarding initial accuracy and temperature coefficient if precise reference stability is required. Ensure the ordering part number matches the exact pin configuration and package type needed for the target PCB layout.
Selection Notes
Select this component for applications requiring both signal comparison and a stable reference voltage within a limited footprint. The low supply current makes it suitable for battery-operated devices. Consider the B grade characteristics for standard accuracy requirements. Verify that the 400ns propagation delay meets the timing constraints of the application.
Part Context
This device belongs to the MAX9038–MAX9043 family of micropower comparators with references. These components are designed for low-voltage, single-supply operation. The MAX9041 specifically integrates a single comparator with a 2.048V reference. It is available in SOT23 packages, offering a compact solution for space-constrained designs.
Replacement Considerations
The MAX9041AEUT+T is a compatible alternative within the same family, differing primarily in the initial accuracy grade of the voltage reference.
