PRINTED CIRCUIT BOARD RECOMMENDATION
Use an unbroken ground plane to have good low impedance and inductance return path to the power supply for
power and audio signals. PCB layout, audio performance and EMI are linked closely together. The circuit
contains high fast switching currents; therefore, care must be taken to prevent damaging voltage spikes. Routing
the audio input should be kept short and together with the accompanied audio source ground. A local ground
area underneath the device is important to keep solid to minimize ground bounce.
Netlist for this printed circuit board is generated from the schematic in Figure 12.
Note T1: PVDD decoupling bulk capacitors C60-C64 should be as close as possible to the PVDD and GND_X pins,
the heat sink sets the distance. Wide traces should be routed on the top layer with direct connection to the pins and
without going through vias. No vias or traces should be blocking the current path.
Note T2: Close decoupling of PVDD with low impedance X7R ceramic capacitors is placed under the heat sink and
close to the pins.
Note T3: Heat sink needs to have a good connection to PCB ground.
Note T4: Output filter capacitors must be linear in the applied voltage range preferable metal film types.
