TLV320DAC3100 I2S DAC Breakout Board with Headphone and Speaker Out

TLV320DAC3100 I2S DAC Breakout Board with Headphone and Speaker Out Description

TLV320DAC3100 I2S DAC with Stereo Headphone and Mono Speaker output - it's got clean, excellent-quality, stereo audio that can connect directly to your 16Ω headphones and/or a 4Ω-8Ω speaker. This makes it excellent for all-in-one audio projects without needing an external amplifier.
This breakout makes amplified I2S digital audio easy. You can power it with 3V (headphone only) or 5VDC (for speaker support) and provide BCLK (bit clock), WSEL (left/right word select), and DIN (data in). Then configure the board with I2C to determine the gain and which output you want activated.
There's tons of configuration options available, but we've used it mostly for 16-bit I2S audio. There's a built-in PLL that will generate an MCLK signal from BCLK for you, so it can be used by any I2S source.
Audio output from the headphone is AC-coupled. Audio from the speaker is a class-D amplifier and must be connected to a speaker only. If you need an external amplifier, use the headphone jack.

There's a few extra breakouts this board: MIC and BIAS are connected to the 'fourth' contact headsets that often have a microphone. You can configure the amp to provide a 2V bias voltage which will let you detect when a headset+mic is plugged in, and also detect when the headset button is pressed. There's also AIN1/AIN2 which are alternative mix-ins for the audio outputs, not I2S encoders. There is one GPIO pin which can also be used as an IRQ .
Please note that while it does not need a MCLK signal (you can configure it to use BCLK as the PLL input) it does require I2C configuration!
