TLV320DAC3100 is an I2S to headphone/speaker DAC 🔊🔩

We're working on getting some more / better I2S options in the shop - we like this TLC320DAC3100 (https://www.digikey.com/short/8w81vmhw)for being able to drive stereo 16Ω headphones and also a single 4Ω 2.5W speaker. We've also had good experiences with the TLV320 series; the only annoyance is that we need to configure the DAC with I2C before using it. However, because a more advanced processor is inside, it can run an equalizer and control volume. There's also a tone generator and headphone detection, and it looks like you can also generate MCLK from BCLK using the onboard PLL. It's also affordable, at $1 in reel quantity. This breakout will help us get this chip working; it exposes everything you need to get started.

Desk of Ladyada - More TLV320 DAC'ing with a Bit of a Run-around 🎧🔍 https://youtu.be/gge8sFjypnQ

This week - We tackle the TLV320DAC3100, fixing headphone & mic issues for a breakout board. Plan to use it in AudioFX remake. Jepler advanced HSTX DVI text mode for Fruit Jam. Also, a search for a new pocket multimeter begins as the fave Amprobe PM51A is discontinued.

TLV320ADCx140 4-Channel microphone I2S ADC 4-Channel microphone I2S ADC 🎤🔊🔧

We saw this TLV320 4-channel microphone ADC in an Echo Dot teardown

and thought it looked like a handy I2S chip. You can have 4 PDM or analog microphones for input, and data comes out on a single stereo I2S channel with time division multiplexing. Four inputs are better than 2 when using microphones for voice array/location projects. This chip doesn't need MCLK, so it would probably work better with a Raspberry Pi! The chip comes in a few flavors, with 106, 120, or 122 dB SNR (you pay more for the 122!) TLV320ADC5140 (as used in the Echo Dot) is in stock at DigiKey

and we'll probably use that one.
