AD1954YSTZ

Overview

The AD1954YSTZ is a SigmaDSP digital audio processor featuring integrated 24-bit, 3-channel delta-sigma DACs. It operates on a single 5 V supply with a maximum clock frequency of 12.288 MHz and supports sampling rates up to 48 ksps. The device utilizes an SPI serial interface for control and data transmission. Housed in a 48-lead LQFP package (7x7 mm), it dissipates a maximum power of 510 mW. Operating temperatures range from -40°C to +105°C, with a typical operating current of 80 mA.

Feature Summary

• Integrated 24-bit resolution with 3 simultaneous output channels
• SigmaDSP architecture with onboard converters
• Single 5 V power supply operation
• SPI serial interface compatibility

Applications

• Professional audio signal processing systems
• High-fidelity digital audio playback equipment
• Multi-channel audio distribution networks

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm RoHS compliance status via official documentation. Ensure storage conditions account for humidity sensitivity requirements specified in the datasheet prior to assembly.

Selection Notes

Select this component for applications requiring high-resolution 3-channel audio conversion within a compact surface-mount footprint. Verify that system power supplies provide stable 5 V rails and that the host controller supports the required SPI communication protocol for configuration and data transfer.

Part Context

This part belongs to the AD1954 series of audio DSPs. It is distinct from evaluation boards such as DC1954A-A, which are designed for testing related clocking components like the LTC6954-1 rather than the audio processor itself.

Replacement Considerations
