TAS5805M Audio Amplifier Showcase

A few weeks back I posted about the TAS5733L; a promising all-in-one I2S codec coupled with a DSP and a class D amplifier. Unfortunately; I could never make it work. Luckily this is not really a problem anymore since Texas Instruments recently released a younger, more powerful brother called the TAS5805M. And it’s an awesome chip!

On the video above you can see the amp playing audio through an ESP32 acting as a bluetooth speaker.

This audio amp will be embedded into a larger project and this board was designed as a proof of concept. The amp itself in the video above is very limited by the tiny 4Ohm 3W speaker that quickly saturates even at very low voltage levels.

I have ordered 4Ohm 20W speakers to really see what this board can do. I’ll make sure to post some update!
