MAX40008ANT+

Overview

The MAX40008ANT+T is a single micro-power comparator from Analog Devices, featuring rail-to-rail inputs and low-voltage operation within a 1.7V to 5.5V supply range. It consumes 12µA of supply current while achieving a typical propagation delay of 220ns. The device includes internal hysteresis for clean switching and a shutdown input that reduces quiescent current to 150nA. It utilizes an open-drain output capable of being pulled beyond VDD up to 6V. Available in a compact 6-bump WLP package, it operates over the -40°C to +125°C automotive temperature range.

Feature Summary

• Features a dedicated shutdown pin that significantly reduces power consumption during inactive periods.
• Incorporates integrated RF immunity filters to enhance signal integrity in noisy environments.
• Provides rail-to-rail input capability with no phase reversal for overdriven signals.
• Utilizes a unique output stage design to minimize supply current surges and eliminate supply glitches.

Applications

• Mobile communications systems
• Portable and battery-powered devices
• Window comparators and threshold detectors
• Logic level translators
• IR receivers

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the 6-bump Wafer-Level Package (WLP) configuration when sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the open-drain output requirement aligns with the MAX40008 variant rather than the push-pull MAX40009. Check for availability constraints or regional sales restrictions prior to finalizing procurement plans.

Selection Notes

Select this component for applications requiring ultra-low power consumption alongside fast response times. The open-drain output allows flexible voltage translation capabilities. Consider the tiny footprint for space-constrained designs. Evaluate the need for external pull-up resistors if utilizing the open-drain configuration for logic interfacing.

Part Context

This part belongs to the MAX40008/MAX40009 family of micro-power comparators designed for low-voltage systems. It shares core specifications with the MAX40009 but differs in output topology. The family targets portable electronics and mobile communications where board space and energy efficiency are critical constraints.

Replacement Considerations

The MAX40009ANT+T serves as a functional substitute if a push-pull output is acceptable instead of the open-drain configuration. Verify that the alternative maintains compatibility with the required supply voltage range and thermal operating conditions.
