AD1895AYRSZRL

Overview

The AD1895AYRSZRL is a 24-bit stereo asynchronous sample rate converter in a 28-lead SSOP package. It supports input and output sampling frequencies up to 192 kHz, with a maximum clock frequency of 215 kHz. The device provides a dynamic range of 128 dB (A-weighted) and total harmonic distortion plus noise ranging from -115 dB to -122 dB. Operating voltages include a 3.3 V core supply and a 3.3 V or 5.0 V I/O supply. It features hardware-controllable soft mute, bypass mode, and TDM daisy-chaining capabilities.

Feature Summary

• Supports 16-, 18-, 20-, and 24-bit data formats with flexible serial interfaces including I2S, TDM, left-justified, and right-justified modes.
• Provides automatic sample frequency sensing without programming requirements and attenuates sample clock jitter.
• Features a linear phase FIR filter with a digital servo loop for accurate interpolation and resampling.
• Includes hardware-controllable soft mute and a bypass mode for direct data passing.

Applications

• Home Theater Systems
• Automotive Audio Systems
• DVD and CD-R Players
• Set-Top Boxes
• Digital Audio Effects Processors

Procurement Notes

Verify the specific ordering suffix 'RL' corresponds to the Tape & Reel packaging option as defined in the manufacturer's ordering guide. Confirm that the component meets the required industrial temperature range specifications (-40°C to +105°C) for the intended application environment before finalizing procurement.

Selection Notes

Select this model when an asynchronous sample rate converter with high dynamic range and low THD+N is required. Ensure the system design accommodates the separate VDD_CORE (3.3 V) and VDD_IO (3.3 V or 5.0 V) power supplies. Verify compatibility with the desired serial interface format, such as I2S or TDM, and confirm that the master clock frequency falls within the specified operational limits.

Part Context

The AD1895AYRSZRL belongs to the AD1895 family of second-generation asynchronous sample rate converters. It builds upon the architecture of the earlier AD1890, offering improved performance metrics and additional interface flexibility. This series is designed for high-fidelity audio applications requiring precise sample rate conversion between asynchronous digital audio sources.

Replacement Considerations

The AD1896 is a related model within the same product family. When considering replacements, verify that the alternative component supports the required 24-bit resolution, 192 kHz sampling rate, and compatible pinout or interface configurations.
