Applications information
TDA7491LP
Emission tests have been performed with a 1-m length of twisted speaker wire with ferrite
beads. Changing the type of the ferrite bead requires care due to factors such as its
effectiveness in the EMC frequency range and impedance stability over the rated current
range. An output snubber network further improves the emissions and this should be tuned
according to the actual PCB, layout and component characteristics.
