MAX98395EWI+T

Audio Amplifiers Overview

The MAX98395EWI+T is a high-efficiency, mono Class-DG speaker amplifier featuring I/V sense and dynamic headroom tracking (DHT). It operates with a wide input supply range of 3.0V to 14V and delivers up to 7.7W into an 8Ω load or 11.7W into a 4Ω load at VPVDD = 12V. The device utilizes spread spectrum modulation and edge rate control for filterless operation. It supports PCM interfaces including I2S, left-justified, and TDM formats, along with an I2C control interface.

Audio Amplifiers Feature Summary

• Class-DG architecture enables industry-leading quiescent power consumption while maintaining high efficiency.
• Integrated precision output current and voltage monitoring allows host devices to run speaker protection algorithms without external components.
• Dynamic headroom tracking automatically optimizes available headroom to maintain consistent distortion and listening levels as supply voltage varies.
• Spread spectrum modulation and edge rate control minimize electromagnetic interference, eliminating the need for traditional output filtering.

Audio Amplifiers Applications

• Mobile Speakers
• Smart Speakers
• Tablets
• Notebook Computers
• Soundbars

Audio Amplifiers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this variant. Confirm that the component meets RoHS3 compliance standards required by your manufacturing process. Ensure the selected distributor provides valid traceability documentation for the Analog Devices Inc./Maxim Integrated part number. Cross-reference the ordering information in the official datasheet to confirm availability status before finalizing procurement plans.

Audio Amplifiers Selection Notes

Select this amplifier for designs requiring ultra-low noise floor and low distortion in a compact form factor. The integrated I/V sense capability simplifies system-level speaker protection implementation. Consider the 28-bump WLP package dimensions for PCB layout constraints. Verify compatibility with the host processor's digital audio interface protocols, specifically I2S or TDM configurations.
