Middle Power Class-D Speaker Amplifiers

ROHM medium power Class D speaker amps feature high efficiency operation with low heat generation, eliminating the need for an external heat sink. High fidelity operation and a broad sound stage are offered with few external parts are required . Available in a compact, space-saving package optimized for thin TVs, docking speakers for portable audio, gaming and gaming devices.Select the ideal IC based on set needs, including analog/digital output and Single End (SE)/BTL output. Models with integrated DSP (Digital Sound Processor) for audio quality/volume adjustment are also offered.
