MAX40008ANT+T

Overview

The MAX40008ANT+T is a single micro-power analog comparator from Analog Devices/Maxim Integrated, housed in a 6-bump WLP package. It operates on a supply voltage range of 1.7V to 5.5V with a typical quiescent current of 12μA and a maximum of 17μA. The device features rail-to-rail inputs, an open-drain output capable of pulling up to 6V above ground, and internal hysteresis. Propagation delay is typically 220ns at 100mV overdrive. It includes a shutdown input that reduces current to 1μA and functions across an automotive temperature range of -40°C to +125°C.

Feature Summary

• Low power consumption with 12μA typical supply current and 150nA shutdown mode
• Rail-to-rail inputs extending beyond supply rails for wide common-mode range
• Internal hysteresis ensures clean switching without external components
• Open-drain output stage allows level translation by pulling beyond VDD

Applications

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

Procurement Notes

Verify the specific ordering suffix ANT+T corresponds to the 6-bump WLP package and tape-and-reel format. Confirm RoHS compliance status as indicated by the plus sign. Ensure the supplier provides valid traceability documentation for automotive-grade parts specified over the -40°C to +125°C range. Cross-reference the manufacturer part number with official Analog Devices databases to confirm current production status and availability constraints.

Selection Notes

Select this component when board space is limited due to its tiny 0.73mm x 1.1mm WLP footprint. Choose it for applications requiring low quiescent current to extend battery life. The open-drain output is suitable for interfacing with different logic voltages. Consider the MAX40009 if a push-pull output is preferred instead of the open-drain configuration found in the MAX40008.

Part Context

This part belongs to the MAX40008/MAX40009 family of single comparators designed for low-voltage, micro-power applications. It shares architectural similarities with other Maxim integrated comparators but distinguishes itself through the combination of ultra-low current, integrated hysteresis, and compact wafer-level packaging. The series targets portable electronics where size and power efficiency are critical design parameters.

Replacement Considerations

The MAX40009ANT+T serves as the functional equivalent within the same package but utilizes a push-pull output stage rather than the open-drain configuration of the MAX40008ANT+T. Verify output drive requirements before substitution. Other members of the MAX4000x series may offer different pinouts or performance characteristics.
