SSM2302 APPLICATION NOTES OVERVIEW The SSM2302 stereo Class-D audio amplifier features a filterless modulation scheme that greatly reduces the external components count, conserving board space and thus reducing systems cost. The SSM2302 does not require an output filter, but instead ...
Page 13
LAYOUT As output power continues to increase, care needs to be taken to lay out PCB traces and wires properly between the amplifier, load, and power supply. A good practice is to use short, wide PCB tracks to decrease voltage ...
