AD1853JRSZ

Overview

The AD1853JRSZ is a stereo digital-to-analog converter (DAC) from Analog Devices, housed in a 28-lead SSOP package. It operates on a single +5 V supply and supports sample rates up to 192 kHz with word lengths of 16, 18, 20, or 24 bits. Key electrical specifications at 48 kHz include a signal-to-noise ratio of 117 dB (stereo, A-weighted) and dynamic range of 116 dB (stereo, A-weighted). Total Harmonic Distortion plus Noise is -104 dB in stereo mode. The device features differential analog outputs and accepts serial data via I2S, left-justified, right-justified, or DSP modes.

Feature Summary

• Multibit Sigma-Delta Modulator with Perfect Differential Linearity Restoration
• On-Chip Clickless Volume Control and Mute Capability
• Flexible Serial Data Port Supporting I2S, Left/Right Justified, and DSP Modes
• Digital De-Emphasis Filters for 32 kHz, 44.1 kHz, and 48 kHz Sample Rates

Applications

• High-End DVD Players
• Home Theater Systems
• Automotive Audio Systems
• Sampling Musical Keyboards
• Digital Mixing Consoles

Procurement Notes

The AD1853JRSZ is listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources rather than direct manufacturing orders. Ensure the specific RS suffix corresponds to the standard shrink small outline package when sourcing replacements.

Selection Notes

Select this component for applications requiring high-performance stereo audio playback with support for up to 192 kHz sampling rates. It is suitable for designs needing integrated digital interpolation and de-emphasis filtering. Verify that the system architecture can accommodate the 28-lead SSOP package and single +5 V power supply requirement.

Part Context

The AD1853 is part of Analog Devices' high-performance audio DAC family. It serves as a complete single-chip solution for digital audio playback systems, integrating a digital interpolation filter, multibit sigma-delta modulator, and continuous-time current-output analog DAC section within one monolithic integrated circuit.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the device is obsolete, alternative components must be selected based on functional equivalence regarding resolution, sample rate, and interface compatibility.
