looking for a I2C controllable audio amplifier | Microchip
https://www.microchip.com/forums/m344356.aspx
A simple I2C interface, anothing else, i.e. a simple loop that samples and outputs, through a lookup-table for audio strength. More than else, I'd like to make it simple, i.e. possibly no or little external parts some 1W audio would be enough, over 8 or 16ohm wall speakers.
TDF8599 | I2C-Bus Controlled Dual Channel 43 W/2 Ohm - …
https://www.nxp.com/products/audio-and-radio/audio-amplifiers/car-audio-amplifiers/ic-bus-controlled-dual-channel-43-w-2-ohm-single-channel-85-w-1-ohm-class-d-power-amplifier-with-load-diagnostics:TDF8599
The TDF8599 is a dual Bridge-Tied Load (BTL) car audio amplifier comprising an NDMOST-NDMOST output stage based on SOI BCDMOS technology. Low power dissipation enables the TDF8599 high-efficiency, class-D amplifier to be used with a smaller heat sink than those normally used with standard class-AB amplifiers.

Digital control allows you to set the volume of the amplifier using a microcontroller via I2C protocol. The I2C data pins are connected on a breakout at the bottom of the board. Assembling Breakout Headers You can solder wires directly to the breakout pads but its easier to prototype if there are headers attached. Follow along to attach headers!
