Schematics is attached.
Gain of the first stage is 1.1 and gain of the TDA chip is 10.
Any comments are appreciated!

No, it follows the datasheet (connection via "B-driver").Is this a joke?
Since the TDA7293 acts as a difference amp, will it multiply the gain by 2 anyway? I ran the same schematics using LM3886 in Tina-TI simulation and output level is at 26 dB

Is it true that 0.1% tolerance resistors should give theoretical CMRR of 66dB, even if used with TDA7293 ?
There is a way to use second TDA7293 in a slave mode while the first one sets the gain.That's interesting! I need to check that out!

I believe this is what the OP is referring to.
ST calls it Modular.
Wow that was in 2012!
I looked at the schematics from the data sheet and it looks pretty involved for that class G implementation. I am little hesitant to use it because of that.
