Product Details

The AD1954 is a complete, 26-bit, single-chip, 3-channel digital audio playback system with built-in DSP functionality. Key features include: 3 channels of digital audio; a 7-band, 48-bit stereo equalizer; delays for loudspeaker location adjustment; Phat Stereo™ spatial enhancement; and a dual-band, professional-quality dynamic processor. Its three DACs achieve 112 dB signal-to-noise ratio (SNR) at 48 kHz. Its dynamic processing features include:

  • Fine-tuned bass boost to enhance low frequencies for small loudspeakers
  • Algorithms that virtually increase loudness by removing distortion at high volumes
  • Midnight mode which automatically reduces loudness in high-volume instances (e.g., sudden loud scenes on DVDs)
  • Low-level expansion to lift low-volume signals above road noise (for car stereos)

The AD1954 SigmaDSP Digital Audio Processor is available in either a 44-pin MQFP or a 48-pin TQFP package and is rated for the extended -40°C to +105°C temperature range. The AD1954 is in Production, and Samples are available. Prices begin at $5.88 in 10,000-piece quantities.
