AD1955 is a high performance multibit ∑- DAC with SACD playback system. This is a complete, high performance, single-chip, stereo digital audio playback system. It is comprised of a multibit sigma delta 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. This has a very flexible serial data input port that allows for glueless interconnection to a variety of ADCs, DSPs, SACD decoders, external digital filters, AES/EBU receivers, and sample rate converters. It can be configured in left justified, I²S, right-justified, or DSP serial port compatible modes. Application includes high end DVD audio, SACD, CD, home theatre systems, automotive audio systems sampling musical keyboards, digital mixing consoles, digital audio effects processors.
