MAX9038BEBT+T

Overview

The MAX9038BEBT+T is a micropower, single-supply analog comparator with an integrated precision voltage reference. It operates from a supply voltage range of 2.5V to 5.5V and consumes only 40μA of quiescent current. The device features rail-to-rail inputs and outputs, with a common-mode input voltage range extending 250mV beyond the supply rails. It includes internal hysteresis of ±3mV and offers a propagation delay of 400ns. The output stage is open-drain, capable of sinking and sourcing up to 8mA. The integrated reference provides a fixed output voltage of 1.23V.

Feature Summary

• Combines 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 for clean switching on slow-moving signals
• Open-drain output design limits 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 EBTT indicates tape and reel packaging when ordering. Confirm RoHS compliance status as indicated by the plus sign in the part number. Check for any recent product change notices or lifecycle status updates directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when a single-supply operation between 2.5V and 5.5V is required alongside a stable 1.23V reference. The open-drain output is suitable for logic-level translation tasks. Consider the 400ns propagation delay and 40μA current consumption for power-sensitive applications where moderate speed is acceptable.

Part Context

This device belongs to the MAX9038–MAX9043 and MAX9050–MAX9053 family of micropower comparators. While other variants in the series offer dual comparators or different reference voltages like 2.048V or 2.500V, the MAX9038 specifically integrates a 1.23V reference with an open-drain output configuration in a 6-bump UCSP package.

Replacement Considerations

Direct replacements within the same family include the MAX9039BEBT+T, which shares identical electrical characteristics but may differ in initial accuracy grades or specific ordering suffixes. Verify pin compatibility and reference voltage requirements when substituting.
