I have built a pcb to use the amplifier mentioned at tittle. I have doubts about the data sheet and the operation mode of the amplifier. I want to know what is the value of vcc1 and vcc2 and their maximum current value, because i have a high measure of this. Another question, i want to know the best way to supply the amplifiers, please give me an answer and an explanation. I post a picture of my design. Thank you very much.
