Note: The amplifier's class-D design outputs a 250Khz PWM-like signal that is restored to an analog voltage in the speaker's coil. This is what makes the amplifier so efficient, but because of the switching frequency, you should keep the amplifier as close to the speaker as possible to minimize possible interference.
Would it be beneficial to use a separate power supply for the amp?If you could give me some advice on how to decouple my circuit (maybe a starting point for experimentation) would be most appreciative.
The grounds are connected expect for the switching power supply I am using for the amp.
Could anyone be willing to make a schematic that I would need in my situation?
but the amp has differential inputs
