... W of continuous output power with less than 10% THD + N driving a 4 Ω load from a single 5.0 V supply. The SSM2305 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 ...

... LC (top) or ferrite bead (bottom) EMI filters. A direct connection to the SSM2305 is established on J6. If EMI filtering is used, insert only one style of EMI filtering on the board. The SSM2305 does not require any external LC output filters due to a low noise modulation scheme. However, if the speaker length is > ...
