MAX9038EBT+T

Overview

The MAX9038EBT+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 includes internal hysteresis of ±3mV and offers a propagation delay of 400ns. The integrated reference provides a fixed output voltage of 1.23V. The component utilizes an open-drain output stage capable of sinking and sourcing up to 8mA.

Feature Summary

• Integrates a low-power comparator with a precision voltage reference in a compact UCSP package
• Features rail-to-rail inputs and outputs with extended common-mode voltage range
• Includes internal hysteresis to ensure clean switching for slow-moving signals
• Open-drain output design minimizes supply current surges during transitions

Applications

• Precision battery management systems
• Window comparator circuits
• Infrared (IR) receivers
• Level translators
• Digital line receivers

Procurement Notes

Verify the specific suffix 'EBT' corresponds to the 6-pin UCSP package and the -40°C to +85°C temperature range. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the part number matches the exact pinout and electrical characteristics required for the target application, as variations exist within the MAX9038 family.

Selection Notes

Select this component when a combination of a low-power comparator and a stable 1.23V reference is required in a minimal footprint. It is suitable for battery-operated applications due to its 40µA supply current. The open-drain output makes it appropriate for level translation tasks. Consider alternative models if dual comparators or different reference voltages are needed.

Part Context

The MAX9038EBT+T belongs to the MAX9038–MAX9043 and MAX9050–MAX9053 family of micropower, single-supply ICs. This series combines comparators with precision voltage references. The MAX9038 specifically integrates a single comparator and a 1.23V reference. Other members of the family offer dual comparators or different reference voltages such as 2.048V and 2.500V.

Replacement Considerations

Direct replacements within the same package and specifications include the MAX9039EBT+T, which shares the same 1.23V reference and open-drain output configuration.
