The EVAL-SSM3582Z is the evaluation board for the SSM3582, an integrated stereo, 31.76W, high efficiency, Class-D, audio amplifier with digital input. The application circuit requires few external components and can operate from a single 4.5 to 16V supply. The SSM3582 features a high efficiency, low noise modulation scheme that requires no external reconstruction filter (LC) output filters. This scheme provides high efficiency, even at low output power.
