AD1896AYRSRL

Overview

The AD1896AYRSRL is a 24-bit, high-performance, single-chip asynchronous sample rate converter manufactured by Analog Devices. It supports input and output sampling frequencies up to 192 kHz with an upsampling ratio of 1:8 and a downsampling ratio of 7.75:1. The device provides 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 accepts 3.3 V or 5 V I/O voltages. The component is housed in a 28-lead SSOP package.

Feature Summary

• Automatically senses sample frequencies without programming requirements
• Attenuates sample clock jitter using a digital servo loop
• Supports TDM daisy-chain mode for multiple devices
• Includes matched-phase mode for synchronized multi-device operation

Applications

• Home theater systems
• Studio digital mixers
• Automotive audio systems
• Digital audio broadcast equipment

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing components. Confirm that the voltage ratings align with system requirements, specifically noting the 3.3 V core and 3.3 V/5 V I/O specifications. Ensure electrostatic discharge precautions are implemented during handling due to device sensitivity.

Selection Notes

Select this component for applications requiring high-fidelity asynchronous sample rate conversion up to 192 kHz. Consider the 28-lead SSOP package constraints for board layout. Evaluate power consumption at target sample rates against available thermal dissipation capabilities. Verify compatibility with existing serial interface formats such as I2S or left/right justified modes.

Part Context

This part belongs to the AD1896 series of second-generation asynchronous sample rate converters from Analog Devices. It builds upon the architecture of the earlier AD1890 model, offering improved performance metrics and additional operational features like bypass and matched-phase modes for complex audio signal processing chains.

Replacement Considerations

The AD1896AYRS is the non-reel variant of this component. Direct functional replacements within the same family should be verified against datasheet specifications to ensure pinout and electrical parameter compatibility.
