Description
The Adafruit TLV320DAC3100 is an I2S DAC breakout board providing stereo headphone and mono speaker output, ideal for all-in-one audio projects without an external amplifier.
This breakout delivers clean, excellent-quality stereo audio directly to 16Ω headphones and 4Ω-8Ω speakers. It supports 3-5V power input and requires I2C configuration using a microcontroller with Arduino, CircuitPython, or Python libraries.
Features include a built-in PLL to generate MCLK from BCLK, headphone audio output that is AC-coupled, and a class-D amplifier for the speaker output. Additional pins provide microphone bias, headset detection, and audio mixing options.
