13.7 Application schematic
The most effective way to avoid pumping effects is to connect the TDA8920C in a mono
full-bridge configuration. In the case of stereo single-ended applications, it is advised to
connect the inputs in anti-phase (see
be adapted; for example, by increasing the values of the supply line decoupling
capacitors.
Notes on the application schematic:
•
•
•
•
•
•
Connect a solid ground plane around the switching amplifier to avoid emissions
Place 100 nF capacitors as close as possible to the TDA8920C power supply pins
Connect the heatsink to the ground plane or to VSSPn using a 100 nF capacitor
Use a thermally conductive, electrically non-conductive, Sil-Pad between the
TDA8920C heat spreader and the external heatsink
The heat spreader of the TDA8920C is internally connected to VSSD
Use differential inputs for the most effective system level audio performance with
unbalanced signal sources. In case of hum due to floating inputs, connect the
shielding or source ground to the amplifier ground.
