SSM2319 THEORY OF OPERATION OVERVIEW The SSM2319 mono 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 SSM2319 does not require an output filter. Instead, ...
Page 15
LAYOUT As output power continues to increase, care must 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 drops ...
