AD1896AYRSZ

Overview

The AD1896AYRSZ is a 24-bit stereo asynchronous sample rate converter from Analog Devices. It supports input and output sampling frequencies up to 192 kHz with ratios ranging from 7.75:1 downsampling to 1:8 upsampling. The device achieves a dynamic range of 142 dB (A-Weighted) and total harmonic distortion plus noise as low as –133 dB. It operates on a 3.3 V core supply and 3.3 V or 5 V I/O supply, functioning within an ambient temperature range of –40°C to +105°C.

Feature Summary

• Automatic sample frequency sensing without programming requirements
• Hardware-controllable soft mute and bypass mode for direct data passing
• Supports multiple serial formats including Left-Justified, I2S, Right-Justified, and TDM
• Matched-phase mode enables synchronized group delay across daisy-chained units

Applications

• Home theater systems
• Studio digital mixers
• Automotive audio systems
• Digital audio effects processors
• Digital tape varispeed applications

Procurement Notes

Verify the RS-28 package option and ensure compatibility with 3.3 V or 5 V I/O levels. Confirm that the operating temperature range meets system requirements of –40°C to +105°C. Check for ESD sensitivity during handling and storage to prevent performance degradation.

Selection Notes

Select this component when high-performance asynchronous conversion between different audio clock domains is required. Ensure the master clock frequency allows for the desired sample rate ratios. Verify that the serial interface modes match the connected DSP or codec requirements.

Part Context

This part belongs to the AD1896 series, representing a second-generation asynchronous sample rate converter. It builds upon the AD1890 architecture with improved jitter rejection and additional serial port flexibility. The AYRSZ suffix indicates the industrial temperature grade and SSOP packaging.
