Overview
The AD1855JRSRL is a stereo audio digital-to-analog converter (DAC) from Analog Devices, housed in a 28-lead SSOP package. It delivers 113 dB dynamic range at 48 kHz and 110 dB at 96 kHz sample rates. The device accepts 16-, 18-, 20-, or 24-bit data via a flexible serial interface supporting Right-Justified, I²S, Left-Justified, and DSP modes. Key specifications include –97 dB THD+N, an on-chip volume control with 1024 steps, and hardware/software controllable mute. It operates on a single +5 V supply within the 0°C to +70°C temperature range.
Feature Summary
- Multibit Sigma-Delta Modulator with Perfect Differential Linearity Restoration
- Supports 24-bit resolution and 96 kHz sample rate
- On-chip Stereo Attenuator with 1024-step Smooth Volume Control
- Flexible Serial Data Port: Right-Justified, I²S, Left-Justified, DSP
Applications
- DVD and CD Players
- Set-Top Boxes
- Home Theater Systems
- Automotive Audio Systems
- Digital Mixing Consoles
Procurement Notes
Verify the RS-28 package variant and reel quantity when sourcing the JRSRL suffix. Confirm RoHS compliance status for current manufacturing lots. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS input structure. Check for any specific environmental certifications required by the target application region.
Selection Notes
Select this component for high-fidelity stereo audio applications requiring low jitter sensitivity and differential outputs. The multibit sigma-delta architecture reduces idle tones compared to traditional 1-bit DACs. Ensure the host system supports the required serial clock frequencies (128x to 512x Fs) and provides adequate power supply rejection filtering for the +5 V rails.
Part Context
The AD1855 belongs to Analog Devices' legacy high-performance audio DAC family. The JRSRL designation specifically indicates the 28-lead Shrink Small Outline Package (SSOP) mounted on 13-inch reels for automated surface-mount assembly. This part is functionally identical to the tube-packaged AD1855JRS but differs only in shipping configuration.
Replacement Considerations
No direct public substitute is listed in the provided documentation. Designers should verify pin compatibility if considering alternative stereo DACs, as interface timing and pinout assignments may vary significantly between different manufacturers' audio DAC families.
