AD1852:  Stereo, 24-Bit, 192 kHz, Multibit Sigma Delta DAC

Product Details


The AD1852 is a complete 18/20/24-bit single-chip stereo digital audio playback system. It is comprised of a multibit sigma-delta modulator, digital interpolation filters, and analog output drive circuitry. Other features include an on-chip stereo attenuator and mute, programmed through an SPI-compatible serial control port. The AD1852 is fully compatible with all known DVD formats including 192kHz as well as 96kHz sample frequencies and 24-bits. It also is backwards compatible by supporting 50/15µs digital de-emphasis intended for "redbook" Compact Discs, as well as de-emphasis at 32kHz and 48kHz sample rate.

FEATURES and BENEFITS

  • 5 V stereo audio DAC system
  • Accepts 16-bit/18-bit/20-bit/24-bit data
  • Supports 24 bits, 192 kHz sample rate
  • Accepts a wide range of sample rates including 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, and 192 kHz
  • Multibit Σ-Δ modulator with perfect differential linearity restoration for reduced idle tones and noise floor
  • Data-directed scrambling DAC—least sensitive to jitter
  • Differential output for optimum performance
  • See datasheet for additional features
