    Hi, TPA3255EVM doesn't have the full PFFB options on board, but you can still do some slightly change on the PCB to implement it. You may take a look at the TPA3251EVM. Thanks! Regards, Sam

    Hi Jerry, Funny you say this. I changed out the NE5532 on the TPA3251EVM a couple of years ago with the OPA1678 device. There should be no problem switching out the op-amps. For the resistors, changing to a 2kohm resistor shouldn't cause any issues. As…

    Hi Darren, You can if you include a single-ended to differential op-amp configuration. I'd recommend looking at the TPA3251EVM to see how we do it. Regards, Robert Clifton
