Overview
The SSM2529ACBZ-R7, produced by Analog Devices Inc., is a digital input, mono 2W Class-D audio power amplifier. This component integrates a digital-to-analog converter (DAC), a low-power audio-specific digital signal processor, and a sigma-delta (Σ-Δ) Class-D modulator. This unique architecture enables extremely low real-world power consumption from digital audio sources while maintaining excellent audio performance. The amplifier is particularly suited for power-sensitive applications such as mobile phones, portable media players, and other devices where system noise can corrupt small analog signals.
