描述

The MAXREFDES9009 is a reference design for a simple, compact, 8-channel digital input audio amplifier, and can deliver up to 14W per channel into an 8Ω load. It is based on the MAX98365, which is a tiny, cost-effective, 14V plug-and-play digital input Class-D amplifier. This design is true plug-and-play and does not require any programming of registers and does not use I2C. Just add power and input signal to get 8-channels of Class-D audio output.

优势和特点

  • True plug-and-play 8-channel digital audio input Class-D amplifier
  • Simple to use and does not require any programming, registers, and I2C
  • Gain is preset to 21.5dB

Just add the following:

  • Power: VDD (1.8V, 3.3V, or 5V), PVDD (3V-14V)
  • Input signal: (digital audio, 16-bit or 32-bit TDM, and 8kHz-192kHz sample rate)
  • 8 Speakers
