MAX20031BATMA/V+

Overview

The MAX20031BATMA/V+ is a high-performance, dual-channel, linear audio amplifier manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single supply voltage ranging from 2.5V to 5.5V and delivers 1W of continuous output power per channel into an 8-ohm load with less than 0.1% total harmonic distortion plus noise at 1kHz. The device features integrated short-circuit protection, thermal shutdown, and soft-start functionality to ensure robust operation in portable applications.

Feature Summary

• Delivers high-fidelity audio performance with low total harmonic distortion plus noise for clear sound reproduction.
• Incorporates built-in short-circuit protection and thermal shutdown mechanisms to safeguard against fault conditions.
• Features a soft-start function that minimizes audible pop-and-hiss artifacts during power-up and power-down cycles.

Applications

• Portable media players and smartphones requiring high-quality stereo audio output
• Tablets and e-readers utilizing single-supply battery power
• Personal navigation systems and GPS devices
