AD1928YSTZ-RL

Overview

The AD1928YSTZ-RL is a high-performance, single-chip audio codec manufactured by Analog Devices Inc. It integrates two analog-to-digital converters (ADCs) with differential inputs and eight digital-to-analog converters (DACs) with single-ended outputs. The device utilizes a multibit sigma-delta architecture to support sample rates from 8 kHz to 192 kHz at 24-bit resolution. It operates on a single 3.3 V supply and features an on-chip phase-locked loop (PLL). Key performance metrics include a dynamic range of 107 dB for the ADC and 108 dB for the DAC, with a total harmonic distortion plus noise of -94 dB.

Feature Summary

• Integrates a PLL-generated or direct master clock to minimize electromagnetic interference.
• Supports multiple serial data formats including I2S, left-justified, right-justified, and TDM modes.
• Includes software-controllable volume control with autoramp and clickless mute functions.
• Features SPI-controlled programmability for flexible system configuration.

Applications

• Automotive audio systems
• Home theater systems
• Set-top boxes
• Digital audio effects processors

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package integrity and pin alignment against the 48-lead LQFP specification. Check manufacturing date codes and lot numbers to ensure compliance with current RoHS standards. Validate that the specific suffix matches the required single-ended output version.

Selection Notes

Select this component when designing systems requiring multi-channel playback with stereo recording capabilities. Ensure the host processor supports the required SPI interface and serial data protocols. Verify that the power supply architecture can provide stable 3.3 V rails for both analog and digital sections. Consider thermal management requirements given the operating temperature range and power dissipation specifications.

Part Context

This part belongs to the AD1928 family of audio codecs. It is specifically the single-ended output variant housed in a 48-lead LQFP package. Other family members may offer differential DAC outputs or different packaging options. The device represents a solution for high-fidelity audio processing within compact integrated circuits.

Replacement Considerations

Public confirmed substitute: AD1928BSTZ-RL. This alternative provides identical functionality but features differential DAC outputs instead of single-ended outputs. Verify pin compatibility and circuit design adjustments for the output stage differences before substitution.
