company blog about Supply Audio Amplifier MAX98360AENL Unique Filterless Design, High Performance Class D Amplifier

Mingjiada Supply Audio Amplifier MAX98360AENL Unique filter-less design, high performance Class D amplifier in a miniature WLP package with no vias and no programming required.

Description

The Audio Amplifier MAX98360AENL is an easy-to-use, low-cost, digital Pulse Code Modulation (PCM) input Class D amplifier that provides industry-leading Class AB audio performance with Class D amplifier efficiency. The digital audio interface automatically recognises different PCM and TDM clock drive methods, eliminating the need for I2C programming. Only power, LRCLK, BCLK and digital audio are required to generate audio. In addition, an innovative pinout allows customers to use highly productive WLP packages without the need for costly vias.

Features
