... THD + N driving a 3 Ω load from a single 5.0 V supply. The SSM2315 comes with a differential mode input port and a high efficiency, full H-bridge at the output that enables direct coupling of the audio power signal to the loudspeaker. The differential mode input stage allows for canceling of common- mode noise ...

... The SSM2315 does not require any external LC output filters because it has a low noise modulation scheme. However, if the speaker length is >10 cm recommended that a ferrite bead (L1 and L2) be placed near each output pin of the SSM2315 to reduce electromagnetic interference (EMI), as shown in the schematic in Figure 4. ...

... Component Placement and Clearance Place all related components except decoupling capacitors on the same side as the SSM2315 and as close as possible to the chip to avoid vias (see Figure 5). Place decoupling capacitors on the bottom side and close to the GND pin (see Figure 7). Top Layer Copper Land and Ground Pouring The output peak current of this amplifier is more than 1 A ...
