STA540 outputs parallel Help!

[Mamun ur rashid]

Hi is it possible to parallel the four outputs into two? (two noninverting outputs and inputs together also inverting inputs and outputs together) I want to do this for better reliability as well as less stress for the chip.

Also, can I add current gain transistor? (like tda2030a 35watt driver design)

Please help! Thanks

You can parallel the outputs for more current meaning it'll drive 4R comfortably in BTL. But you'll need to use capacitors as the DC offset at the outputs could be too large to handle with the usual sharing resistors (up to 150mV).
