Product Overview

The AD1955ARSZ is a Multibit Sigma-Delta (Σ-Δ) DAC with SACD playback with a very flexible serial data input port that allows for glueless interconnection to a variety of ADCs, DSPs, SACD decoders, external digital filters and AES/EBU receivers. It is a complete, high performance, single-chip, stereo digital audio playback system comprised of a multi-bit Sigma-Delta (Σ-Δ) modulator, high performance digital interpolation filters and continuous-time differential current output DACs. Other features include an on-chip clickless stereo attenuator and mute capability, programmed through an SPI compatible serial control port. The AD1955 is fully compatible with all known DVD audio formats. It is also backward compatible by supporting 50µs/15µs digital de-emphasis intended for Redbook compact discs, as well as de-emphasis at 32kHz and 48kHz sample rates. Multibit sigma delta modulator with "Perfect Differential Linearity Restoration" for reduced idle tones and noise floor.
