AD1933YSTZ

Digital To Analog Converters Overview

The AD1933YSTZ is a high-performance, single-chip audio codec from Analog Devices featuring eight digital-to-analog converters (DACs) with differential outputs. Utilizing a patented multibit sigma-delta architecture, it operates on a single 3.3 V supply and supports sample rates from 8 kHz to 192 kHz at 24-bit resolution. The device includes an integrated phase-locked loop (PLL) for clock generation, SPI control, and low EMI design features. It provides 110 dB dynamic range and -96 dB THD+N in differential mode, housed in a 64-lead LQFP package suitable for automotive applications.

Digital To Analog Converters Feature Summary

• 110 dB dynamic range and SNR; -96 dB THD+N (differential)
• Integrated PLL or direct master clock support up to 192 kHz
• SPI controllable with log volume control and autoramp function

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature grade. Ensure the component meets AEC-Q100 qualification requirements if intended for automotive use. Cross-reference pin configurations and electrical specifications with the latest revision of the official datasheet before integration.

Digital To Analog Converters Selection Notes

Select this component when differential DAC outputs are required for noise immunity in multi-channel audio applications. The AD1933 is appropriate for designs needing integrated clock generation via PLL to reduce external components. Verify that the system can accommodate the 64-lead LQFP package dimensions and thermal requirements for the specified operating temperature range.

Digital To Analog Converters Part Context

The AD1933 belongs to the AD193X family of high-performance codecs. Unlike the AD1938 or AD1939 which include analog-to-digital converters (ADCs), the AD1933 is a dedicated DAC-only solution. It shares architectural similarities with other family members but focuses exclusively on digital-to-analog conversion with differential outputs in a 64-lead package.

Digital To Analog Converters Replacement Considerations

For single-ended output requirements within the same family, consider the AD1938 or AD1939 variants. If ADC functionality is needed, the AD1938 or AD1939 are suitable replacements. Direct pin-compatible substitutes are not explicitly listed in the provided documentation; verify compatibility with AD1933WBSTZ for potential packaging differences.
