MAX40014ANS09+T

Overview

The MAX40014ANS09+T is a nanoPower single comparator in an ultra-tiny 4-bump WLP package with a 0.73mm x 0.73mm footprint. It operates on a supply voltage range of 1.7V to 5.5V and consumes only 500nA of supply current. The device features a noninverting input, push-pull output, and a factory-trimmed internal reference voltage of 0.9V (typical). Input voltage ranges from 0.1V to 5.5V, independent of the supply voltage. It maintains high impedance at inputs when powered down and includes internal filtering for RF immunity.

Feature Summary

• Ultra-low power consumption preserves battery life in portable applications
• Tiny 4-bump wafer-level package saves board space
• Internal 0.9V reference eliminates external components
• Push-pull output stage simplifies circuit design

Applications

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

Procurement Notes

Verify the specific suffix '09' confirms the 0.9V internal reference voltage. Confirm the 'ANS' designation indicates the 4-bump WLP package type. Ensure the '+T' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Selection Notes

Select this part when board space is extremely limited and low quiescent current is critical. The push-pull output removes the need for external pull-up resistors. Verify that the fixed 0.9V internal threshold meets the application's detection requirements without needing external references.

Part Context

This component belongs to the MAX40002–MAX40005 and MAX40012–MAX40015 family of nanoPower comparators. These devices are designed for compact, low-voltage applications where power conservation and minimal footprint are primary design constraints.

Replacement Considerations

Other members of the MAX4001x series may serve as alternatives if different reference voltages or input polarities are required. Verify package compatibility and electrical specifications before substitution.
