MAX40003ANS02+T

Overview

The MAX40003ANS02+T is a single-channel analog comparator from the nanoPower family, housed in a 4-bump WLP package with a 0.73mm x 0.73mm footprint. It features an inverting input and an open-drain output. The device operates on a supply voltage range of 1.7V to 5.5V, consuming a typical supply current of 500nA. It includes a factory-trimmed internal reference voltage preset at 0.2V. Electrical characteristics include a propagation delay of 9µs (typical) and an input offset voltage of 500µV (typical). It supports an input voltage range of 0.1V to 5.5V and functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Ultra-low power consumption preserves battery life in portable applications
• Tiny 4-bump wafer-level package saves board space
• Internal filtering provides high RF immunity
• High impedance maintained at inputs even when powered down

Applications

• Mobile devices
• Portable medical devices
• Notebook computers
• Electronic toys

Procurement Notes

Verify the specific suffix '02+' indicates the 0.2V internal reference configuration. Confirm the 'T' suffix denotes tape and reel packaging. Ensure compatibility with the required inverting logic and open-drain interface requirements for the target circuit design.

Selection Notes

Select this component for designs requiring minimal footprint and ultra-low quiescent current. The inverting input polarity dictates that the output asserts low when the input exceeds the reference. Verify that the open-drain output architecture aligns with the downstream logic level shifting needs.

Part Context

This part belongs to the MAX40002–MAX40005 series of nanoPower comparators. These devices are designed for compact, low-voltage applications where board space and power constraints are critical. The series offers various combinations of input polarities, output types, and internal reference voltages.

Replacement Considerations

Cross-reference with other MAX40003 variants such as MAX40003ANS+T or MAX40003AUK02+T if different packaging or reference options are needed.
