MAX9892ELT+T

Audio Special Purpose Overview

The MAX9892ELT+T is a shunt-mode audio click-and-pop eliminator designed for portable multimedia devices. It connects to the output of existing system amplifiers, providing a low-impedance path to ground during startup and shutdown to prevent audible transients. The device features two low-impedance analog switches controlled by a MUTE pin, which remain open during normal operation. It operates from a single supply voltage ranging from 1.7V to 3.6V, with inputs accepting swings up to VDD - 5.5V. The component draws less than 1µA of supply current and is housed in a 6-pin µDFN (2mm x 2mm) package.

Audio Special Purpose Feature Summary

• Distortion-free click-and-pop elimination via shunt-mode architecture
• Ultra-low supply current consumption of less than 1µA
• Adjustable turn-off time using an external capacitor on the SET pin
• Operates on a single 1.7V to 3.6V supply with high input voltage tolerance

Audio Special Purpose Applications

• Mobile phones
• Smart phones
• Portable media players
• Notebook computers

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix ELT corresponds to the 6-pin µDFN (2mm x 2mm) package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement. Ensure the design supports the required 1.7V to 3.6V supply range for optimal performance.

Audio Special Purpose Selection Notes

Select this component when distortion-free transient suppression is required for headphone amplifiers in space-constrained designs. The 6-pin µDFN package is suitable for applications requiring a compact footprint. Designers must account for the adjustable turn-off time circuitry and proper supply voltage scaling to handle negative audio signal swings effectively.

Audio Special Purpose Part Context

The MAX9892ELT+T belongs to the MAX9892 family of audio click-and-pop eliminators. This second-generation device improves upon previous iterations by offering precise control over turn-on and turn-off transients. It is specifically engineered to interface with conventional headphone amplifiers in portable consumer electronics.
