Overview
The MAX9051AESA is a micropower, single-supply comparator and precision voltage reference IC in an 8-pin SO package. It features one comparator with rail-to-rail inputs and outputs, consuming only 40μA of supply current. The device operates from a 2.7V to 5.5V supply. It includes a 2.500V precision voltage reference with ±0.4% initial accuracy (A grade) and a typical temperature coefficient of 6ppm/°C. The comparator offers a propagation delay of 400ns, internal hysteresis, and an output stage capable of sinking and sourcing up to 8mA.
Feature Summary
- Integrates a low-power comparator with a precision voltage reference for battery-operated systems
- Features rail-to-rail input and output stages with extended common-mode voltage range
- Includes internal hysteresis to ensure clean switching with slow-moving signals
- Output driver design minimizes supply current surges during transitions
Applications
- Precision Battery Management
- Window Comparators
- IR Receivers
- Level Translators
- Digital Line Receivers
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm that the A-grade designation matches the required initial accuracy and temperature coefficient specifications for your application. Ensure the 8-pin SO package footprint aligns with your board layout requirements before procurement.
Selection Notes
Select this component when a single comparator combined with a stable 2.5V reference is required in a compact 8-pin SO package. It is suitable for applications needing rail-to-rail signal handling and low quiescent current. Consider alternative grades or packages if higher accuracy or different pin counts are necessary.
Part Context
This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparators and references. The MAX9051 variant specifically provides a single comparator and a 2.500V reference. It shares core architectural features with other members of the series, such as the MAX9050 and MAX9052, differing primarily in the number of comparators and reference voltage options.
Replacement Considerations
Direct substitutes within the same family include the MAX9050 (same reference, UCSP/SOT23 package) and MAX9052 (dual comparator). Verify pinout compatibility and package dimensions when considering these alternatives.
