AD1895YRSRL

Overview

The AD1895YRSRL is a stereo asynchronous sample rate converter from the AD1895 series, manufactured by Analog Devices Inc. It supports input and output sample rates up to 192 kHz with upsampling ratios of 1:8 and downsampling ratios down to 7.75:1. The device features a dynamic range of 128 dB (A-weighted) and THD+N performance ranging from -115 dB to -122 dB. It operates on a 3.3 V core supply with input voltages between 3.3 V and 5.5 V. The component is housed in a 28-lead SSOP package and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Automatic sample frequency sensing without programming requirements
• Supports 16-, 18-, 20-, and 24-bit data formats
• Hardware-controllable soft mute and bypass mode
• Flexible 3-wire serial interface supporting I2S, Left-Justified, Right-Justified, and TDM modes

Applications

• Digital audio interfacing
• Home theater systems
• Automotive audio systems
• DVD and CD-R players
• Set-top boxes

Procurement Notes

Verify the specific ordering suffix YRSRL against official documentation to confirm reel packaging and any functional variations compared to standard tube versions. Ensure compatibility with existing board layouts for the 28-SSOP footprint and validate voltage levels for the 3.3 V to 5.5 V supply range before integration.

Selection Notes

Select this component when high-performance stereo conversion up to 192 kHz is required. The AD1895 offers improved jitter rejection and linear phase FIR filtering compared to earlier generations. Consider the 28-SSOP package constraints and the need for flexible serial port modes when designing the digital audio interface.

Part Context

The AD1895 is part of Analog Devices' second-generation asynchronous sample rate converter family, succeeding the AD1890. It provides enhanced performance metrics including better jitter attenuation and expanded serial format support. The device is designed for professional and consumer audio applications requiring precise sample rate conversion between different digital audio standards.

Replacement Considerations

The AD1890 is a previous generation alternative but lacks some performance improvements. Verify pinout compatibility and software configuration differences if substituting other models in the AD189x series.
