Overview
The SSM3582ACPZ-RL, produced by Analog Devices Inc., is a high-efficiency, digital input stereo Class-D audio amplifier. This device is designed to operate from a single 4.5 V to 16 V supply, making it versatile for various audio applications. It features a proprietary, spread spectrum Σ-Δ modulation scheme that ensures state-of-the-art analog performance and reduces radiated emissions. The amplifier is capable of delivering 2 × 15 W rms continuously into 8 Ω and 4 Ω loads with less than 1% total harmonic distortion (THD), and it maintains excellent power efficiency across a wide range of impedances.
