Part Number: TPA3255
Hello, when i design a pcb for a tpa32xx serie chip, can i without any problems (just i assume i should get i get a weaker output signal as stated) connect the A and D inputs to a single-ended source in BTL mode (A pin to right channel input and D pin to left channel input) and B and C pins to dc blocking capacitors of an equal value than the A and D pins (10uf) to ground (like it is possible with tpa3116 amplifier or tpa3220/3221 amplifiers)?
Or did i am forced to use a single-ended to differencial output converter made with op amps (that increase the cost and degrade the sound quality but allow me to get the full output power and; maybe depending by the noise floor level of op amps, to get less output noise, because the inputs are differencial)?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Ok, but i think that i will get a better sound quality with a tpa325x/324X based amplifier? Also, did a air core inductor provides a better sound quality than magnetic core ones?

Hello, i see that the tpa3245 is the best oriented chip for the way i want to build my prototype, (by some of the facts that ouput noise at the lowest of tpa324x/325x family and output power and entry impedance perfectly fit to my needs). But the problem is that output impedance must be 4 ohm max (as show on the datasheet), but, can i use 8 ohm speakers (as i wouldn't use the chip until it reach max output power and will use 32v main supply) ?
