Overview
The AD1855JRS is a stereo audio digital-to-analog converter (DAC) from Analog Devices, housed in a 28-lead SSOP package. It supports 16-, 18-, 20-, and 24-bit data with sample rates up to 96 kHz. The device delivers 113 dB dynamic range at 48 kHz and 110 dB at 96 kHz, with –97 dB THD+N. It operates on a single +5 V supply, drawing 30 mA analog current and 20 mA digital current. Key features include a multibit sigma-delta modulator, differential outputs, on-chip volume control with 1024 steps, clickless mute, and flexible serial interfaces including I2S, left/right justified, and DSP modes.
Feature Summary
- Multibit Sigma-Delta Modulator with Perfect Differential Linearity Restoration
- 113 dB Dynamic Range at 48 kHz; 110 dB at 96 kHz
- On-Chip Volume Control with 1024 Steps and Clickless Mute
- Flexible Serial Data Port: I2S, Left/Right Justified, DSP Compatible
Applications
- DVD and CD Players
- Set-Top Boxes
- Home Theater Systems
- Automotive Audio Systems
- Digital Mixing Consoles
Procurement Notes
Verify the specific suffix JRS indicates the standard 28-lead SSOP plastic package for commercial temperature range (0°C to +70°C). Confirm that the ordering guide lists AD1855JRSRL as the reel variant if tape-and-reel packaging is required instead of tube. Check for end-of-life status or alternative recommendations from Analog Devices as this component may be discontinued.
Selection Notes
Select the AD1855JRS when a high-performance stereo DAC with integrated filtering and output drive is needed. Ensure the system clock can provide 128x, 256x, 384x, or 512x the sample frequency. Verify compatibility with the host processor's serial interface mode (I2S, Left/Right Justified, or DSP). Consider the AD1855JRSRL if automated surface-mount assembly requires reel packaging rather than tubes.
Part Context
The AD1855JRS is part of the AD1855 family of stereo audio DACs. It is fabricated on a single monolithic integrated circuit and designed for high-fidelity audio applications. The 'J' suffix typically denotes the commercial temperature range, while 'RS' specifies the shrink small outline package. It serves as a complete solution for converting digital audio streams to analog signals with minimal external components.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Analog Devices for current product recommendations if the AD1855JRS is no longer available.
