The AD1954 is a complete 26-bit single-chip 3-channel digital audio playback system with built-in DSP functionality for speaker equalization, dual-band compression/limiting, delay compensation, and image enhancement. These algorithms can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, resulting in a dramatic improvement of perceived audio quality.The signal processing used in the AD1954 is comparable to that found in high-end studio equipment. Most of the processing is done in full 48-bit double-precision mode, resulting in very good low-level signal performance and the absence of limit cycles or idle tones. The compressor/limiter uses a sophisticated two-band algorithm often found in high-end broadcast compressors.An extensive SPI port allows click-free parameter updates, along with read-back capability from any point in the algorithm flow.The AD1954 includes ADI’s patented multibit sigma-delta DAC architecture. This architecture provides 112 dB SNR and dynamic range and THD+N of –100 dB. These specifications allow the AD1954 to be used in
