The AD1855JRS is a stereo 24-bit audio DAC from Analog Devices designed for high-performance audio applications. It incorporates a multibit sigma-delta modulator with Perfect Differential Linearity Restoration to minimize idle tones and noise floor. The device supports sample rates up to 96 kHz and accepts 16-, 18-, 20-, and 24-bit data.
Key performance specifications include a typical signal-to-noise ratio of 113 dB at 48 kHz and 110 dB at 96 kHz, dynamic range matching the SNR figures, and a total harmonic distortion plus noise of -97 dB. The DAC operates from a single 5 V supply and offers flexible serial data interfaces: I2S, DSP, Left-Justified, and Right-Justified formats.
The AD1855JRS is housed in a 28-lead SSOP plastic package with a 0.209 inch width, suitable for surface mount assembly. On-chip features include a 1024-step volume control, clickless mute, digital de-emphasis processing, and a zero flag output for each channel. The device also supports multiple master clock rates (128, 256, 384, and 512 FS) and a switchable clock doubler.
The AD1855JRS has a resolution of 24 bits.
The maximum sampling rate is 96 kHz.
The typical SNR is 113 dB at 48 kHz and 110 dB at 96 kHz (A-weighted).
The typical THD+N is -97 dB.
It comes in a 28-lead SSOP surface mount package (28-SSOP, 0.209" width).
The nominal supply voltage is 5 V.
Based on existing database records, it is marked as RoHS3 Compliant, but this data is unverified.
