EVAL-SSM3582Z: Class D, 31.76W x 2 @ 4Ω, 4.5 ~ 16V in

The EVAL-SSM3582Z is the evaluation board for the SSM3582, an integrated stereo, 31.76 W, high efficiency, Class-D, audio amplifier with digital input. The application circuit requires few external components and can operate from a single 4.5V to 16V supply.

The EVAL-SSM3582Z is capable of delivering 14.67W of continuous output power to a 4Ω load from a 12V power supply, with <1% THD + N, or 31.76W into a 4Ω load from 16V, 10% THD + N.

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.

The EVAL-SSM3582Z and the SSM3582 operate with 93.8% efficiency at 10 W into an 8 Ω load or 90.6% efficiency at 18 W into 4 Ω load from a 12 V supply. The EVAL-SSM3582Z and the SSM3582 have a typical noise floor of 38.5 μV rms A weighted.

This user guide describes how to configure and use the SSM3582 evaluation board. Read this user guide in conjunction with the SSM3582 data sheet, which provides specifications, internal block diagrams, a register map, and application guidance for the amplifier.
