AD1934YSTZ-RL

Digital To Analog Converters Overview

The AD1934YSTZ-RL is an eight-channel digital-to-analog converter (DAC) featuring single-ended outputs, manufactured by Analog Devices Inc. It utilizes a patented multibit sigma-delta architecture to deliver high-fidelity audio conversion with a dynamic range of 108 dB and total harmonic distortion plus noise of -94 dB. The device supports sample rates from 8 kHz to 192 kHz at 24-bit resolution. It operates on a single 3.3 V supply and includes an integrated phase-locked loop (PLL) for clock generation. The component is housed in a 48-lead LQFP package and is qualified for automotive applications.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YSTZ-RL' against the manufacturer's current ordering guide to confirm packaging and availability status. Confirm that the automotive qualification requirements align with the project specifications before finalizing procurement decisions.

Digital To Analog Converters Selection Notes

Select this component when eight single-ended analog outputs are required within a compact 48-lead LQFP footprint. Ensure the system design accommodates a 3.3 V power supply and provides adequate bypassing for the internal voltage reference. Verify compatibility with the desired serial data format, such as I2S or TDM, during the initial design phase.

Digital To Analog Converters Part Context

This part belongs to the AD193x family of high-performance audio codecs. While the AD1934 provides single-ended outputs, other variants in the series offer differential output configurations. The device is designed for low electromagnetic interference (EMI) through its continuous-time architecture and optimized clocking schemes.

Digital To Analog Converters Replacement Considerations

The AD1933WBSTZ-RL is listed as a direct substitute in distributor databases. However, the AD1933 features differential DAC outputs rather than single-ended outputs. Verify pinout compatibility and signal routing changes before implementing any substitution.
