AD1959YRS

The AD1959YRS is a 5 V stereo audio digital-to-analog converter (DAC) from Analog Devices. It integrates a multibit sigma-delta modulator with data directed scrambling to deliver high-performance audio conversion. The device accepts 16-, 20-, and 24-bit serial digital audio data and supports sample rates from 32 kHz up to 192 kHz, covering common audio formats including CD and high-resolution audio.

Key performance specifications include a typical signal-to-noise ratio of 108 dB, dynamic range of 108 dB, and total harmonic distortion plus noise (THD+N) of -94 dB. An integrated programmable fractional-N PLL clock generator accepts a 27 MHz master clock and produces the necessary system clocks, reducing external jitter. The analog output is single-ended, simplifying the output stage design. A serial SPI control interface provides access to volume, mute, de-emphasis, and output phase settings.

The AD1959YRS is supplied in a 28-lead surface-mount SSOP package. It requires a nominal 5 V analog supply. This DAC is suitable for a wide range of audio and data acquisition applications where high dynamic range and low distortion are required.
