説明

The D2-6 family (D2-71083, D2-74083, D2-71583, D2-74583, and D2-74383) digital audio processor devices are complete System-on Chip (SoC) audio processor and Class-D amplifier controllers. Integrated DSP processing and configurable audio processing algorithms provide an extremely flexible platform for feature rich and cost-effective quality audio solutions which benefit from the addition of Class-D amplifiers and DSP audio processing, meeting demands of consumer electronics applications. The 12 integrated digital PWM controllers can be used in a variety of multi-channel audio system configurations, supporting powered as well as line outputs. Fully protected amplifier control provides efficient and clean Class-D power output support. The D2-6 device family supports full audio decoding for formats including Dolby® Digital, Dolby® Pro Logic IIx, AAC LC™, DTS® Digital Surround, and Dolby® Digital Plus. The D2-6 family is pin-compatible and function/feature compatible with the D2-3 family devices, enabling additional decoding capability to existing designs, or providing cost optimization to lower-featured systems not requiring the additional audio processing and decode capability.

    R32AN0007: Output Filter Design Selection
    PDF 184 KB r32an0007eu0100-d2-audio-dsp-output-filter-design 2019年5月20日
    AI生成コンテンツ: The document explains the design and selection of output filters for D2 Audio DSP half-bridge and full-bridge configurations. It details the half-bridge output stage, filter network, and bias network that provides a DC offset and AC ground reference. It covers filter operation principles, emphasizing the second-order LC low-pass filter to attenuate high-frequency PWM signals. Loudspeaker impedance impacts filter damping and response. Recommended component values for inductors, capacitors, and bias networks are provided for various load impedances and power ratings.
