TDA7293 Bridge Parallel Circuit

[VikramRaj4ever]

Hello, I want to make TDA7293 Bridge/Parallel Amp (as like BPA200 LM3886 Amp).
TDA7293 datasheet show parallel circuit & TDA7294 datasheet show bridge circuit.

I want to know about TDA7294 bridge circuit where capacitor in series with 680 ohm resistor is not connected & why 22k ohm resistor connected between inverting pin of one chip and output pin of another chip.

If i use same bridge circuit of TDA7294 in TDA7293 than what change must be done. If i connect bootstrap pin with bootstrap loader pin than a capacitor is required or not in series with 680 ohm resistor.

I want to use TDA7293 in Parallel because these not reruired precision resistor value for gain setting in parallel mode. (as like BPA200)

BPA200
TDA7293
TDA7294

Please answer. Thanks
