Default Sure TPA3123D2 2*25W Amp

These class D amps can be configured in SE or BTL mode.The 2*25W Sure amp is set up as stereo.I don't think these are like the T amps.
Can this Sure amp be bridged?Should I invert one of the inputs?
thanks
coit

You would need some external method of inverting the signal to one of the inputs. Keep in mind the minimum load Resistance is 8R for BTL.

For BTL operation you can bypass the output capacitors.
