Description

The AD1955ARSZ is a kind of 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 continuoustime differential current output DAC section.

Features of the AD1955ARSZ are:(1)5V power supply stereo audio DAC system; (2)it accepts 16/18/20/24-bit data; (3)it supports 24-Bits, 192kHz sample rate PCM audio data; (4)it supports SACD bit-stream and external digital filter interface; (5)it accepts a wide range of PCM sample rates including:32kHz, 44.1kHz. 48kHz, 88.2kHz, 96kHz, and 192kHz; (6)multibit sigma delta modulator with "perfect differential linearity restoration" for reduced idle tones and noise floor; (7)data directed scrambling DAC - least sensitive to jitter; (8)it supports SACD playback with "bit expansion" filter; (9)differential current output for optimum performance; (10)8.64 mA p-p output current with +3dB headroom in SACD mode.

The absolute maximum ratings of the AD1955ARSZ can be summarized as:(1): DVDD to DGND is -0.3 V min and 6 V max; (2): AVDD to AGND is -0.3 V min and 6 V max; (3): digital inputs DGND is - 0.3 V min and  DVDD + 0.3 V max; (4): analog outputs AGND is - 0.3 V min and AVDD + 0.3 V max; (5): AGND to DGND is -0.3 V min and 0.3 V max; (6): reference voltage  is (AVDD + 0.3)/2 max.
