SSM2305-EVALZ

SSM2305-EVALZ is an evaluation board for SSM2305 fully integrated, single-chip, mono Class-D audio amplifier that is designed to maximize performance for mobile phone applications. The application circuit operates from a single 2.5V to 5.5V supply and is capable of delivering 2.8W of continuous output power with less than 10% THD + N driving a 4ohm load from a single 5V supply. The SSM2305 comes with differential mode input port and a high efficiency, full H-bridge at the output that enables direct coupling of the audio power signal to the loudspeaker. The differential mode input stage allows for cancelling of common-mode noise. The part also features a high efficiency, low noise output modulation scheme that requires no 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 the nonlinearities of output LC filters.

• Single-ended and differential input capability
• User-friendly interface connection
• Optimized EMI suppression filter assembled on board
