Features and Benefits

  • 15.3 W into 4 Ω at 12 V 1% THD + N

Product Details

The EVAL-SSM3525Z is an evaluation board for the SSM3525, which is an integrated mono 30 W, high efficiency, stereo Class-D audio amplifier with digital input. The application circuit requires a few external components and can operate from a single 4.5 V to 17 V supply. It is capable of delivering 15.3 W of continuous output power into a 4 Ω load from a 12 V power supply, with <1% total harmonic distortion plus noise (THD + N).

The SSM3525 features a high efficiency, low noise modulation scheme that requires no external inductor/capacitor (LC) output filters. This scheme continues to provide high efficiency even at low output power.

The SSM3525 operates with 92.1% efficiency at 9 W into an 8 Ω load, and it has a typical output noise voltage of 37.5 μV rms, A weighted.

User Guide UG-1183 describes how to configure and use the EVAL-SSM3525Z evaluation board. Read this user guide in conjunction with the SSM3525 data sheet, which provides specifications, internal block diagrams, register map, and application guidance for the amplifier IC.
