no experience so far.
but have one right in front of me on the desk.
i try to figure out what the actual circuit is compared to the datasheet.
i'm going to solder a strip of 12 pin headers on it and build the rest of the datasheet-circuit on perfboard.
the output lc filter and the recommended snubber are not onboard.
the ic produces a voltage vreg (4V at Pin 15) which sets FAULT (pin 46), MUTE (pin 45), SD (shutdown) (pin 44) into on and off status.
there is no VREG output from the YL2020 board, but the FAULT, MUTE, SD have to be set external.
as the datasheet recommends to not leave those pins unconnected, i will get started with this amp as soon as i found a solution to get control of those pins.
the gain control pins are both connected via a 10k resistor to VREG.
i like how the R-output is close to the pin.
although the bootstrap cap of the L-output is close to the chip, the trace towards the board-output is looooooong.
.....just some observations.

Hi Buehgemeiste,

Thanks for your response. I will appreciate any info of your experience with it. I am building a mini guitar amp, I have built many lm386 mini amps but I want more headroom. I have tested the PAM8610 module and I am very disappointed with it.
