ADI's SSM3515/SSM3582 are fully integrated, high efficiency, digital input stereo Class-D audio amplifiers. These devices can operate from a single supply, and require only a few external components, significantly reducing the circuit bill of materials. The SSM3582 operates from a single 4.5 V to 16 V supply and is capable of delivering 2 × 15 W RMS continuously into 8 Ω and 4 Ω loads at <1% total harmonic distortion (THD). The SSM3515 can deliver 8.4 W of output power into an 8 Ω load or 15.8 W into a 4 Ω load from a 12 V power supply, or 31.3 W into a 4 Ω load from a 17 V power supply. These devices operate with or without an I²C control interface and have an operating temperature of  (-40°C to +85°C). They both have built in thermal shutdown and output short-circuit protection. The SM3515 are available in a 20-WLCSP package, whereas the SSM3582 come in a 40-LFCSP package.
