Layout and Grounding Considerations
Well designed PC board layout is essential for optimizing device performance. Use large traces for the power supply
inputs and amplifier outputs to minimize losses due to parasitic trace resistance and route heat away from the device.
Sufficient grounding improves audio performance, minimizes crosstalk between channels, and prevents digital switch-
ing noise from coupling onto the audio signal.
