SSM2302Z-EVAL: 2x 1.4 W @ 8Ω, 3 ~ 5 Vin

The SSM2302 is a single-chip, single-channel, stereo Class-D audio amplifier. It is a fully integrated chip, which means that the application circuit requires a minimum of external components. It comes with a differential mode input port and a high efficiency H-bridge at the output. When compared to a half-bridge output stage, a full H-bridge enables direct coupling of the audio power signal to the loudspeaker, doubling the output voltage swing and eliminating the need for a large output coupling capacitor.

Moreover, the part features a high efficiency, low noise output modulation scheme that does not require external LC output filters when attached to an inductive load. The modulation provides high efficiency even at low output power. Filterless operation also helps to decrease distortion due to nonlinearities of output LC filters, thereby providing a better sound quality and leading to savings in board space and overall cost.

This data sheet describes how to configure and use the SSM2302 evaluation board. It is recommended that this data sheet be read in conjunction with the SSM2302 data sheet, which provides more detailed information about the specifications, internal block diagrams, and application guidance for the amplifier IC.
