Product Details

The EVAL-SSM3582Z is the evaluation board for the SSM3582 or the SSM3582A, integrated stereo, 31.76 W, high efficiency, Class D, audio amplifiers with a digital input. This evaluation board can be used for both the SSM3582 or the SSM3582A devices.

The application circuit requires few external components and can operate from a single 4.5 V to 16 V supply. The EVALSSM3582Z is capable of delivering 14.67 W of continuous output power to a 4 Ω load from a 12 V power supply, with <1% THD + N, or 31.76 W into a 4 Ω load from 16 V, 10% THD + N.

The SSM3582 and the SSM3582A feature 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 or the SSM3582A 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 EVALSSM3582Z, the SSM3582, and the SSM3582A have a typical noise floor of 38.5 µV rms A weighted.

This user guide describes how to configure and use the EVALSSM3582Z. Read this user guide in conjunction with the SSM3582 and the SSM3582A data sheets, which provide specifications, internal block diagrams, a register map, and application guidance for the amplifiers.
