SSM2529ACBZ-R7

SSM2529 is a digital input, Class-D power amplifier that combines a digital-to-analogue 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 with excellent audio performance. The SSM2529 is ideal for power sensitive applications, such as mobile phones and portable media players, where system noise can the corrupt small analogue signals that are sent to an analogue input audio amplifier. Using the SSM2529, audio data can be transmitted to the amplifier over a standard digital audio serial interface, thereby significantly reducing the effect of noise sources such as GSM interference or other digital signals on the transmitted audio. Application includes mobile phones, portable media players, laptop PCs, wireless speakers, portable gaming, navigation systems.
