Overview
The MAX98357AETE+T is a compact, low-cost, digital pulse-code modulation (PCM) input class D amplifier designed by Analog Devices Inc./Maxim Integrated. This amplifier offers industry-leading class AB audio performance with the efficiency of a class D amplifier. It is particularly notable for its ease of use, as it automatically recognizes up to 35 different PCM and TDM clocking schemes, eliminating the need for I²C programming and external MCLK signals. This simplifies the operation to just supplying power, LRCLK, BCLK, and digital audio to generate high-quality audio output.
