CS4333-KS

Digital To Analog Converters Overview

The CS4333-KS is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic Inc., housed in an 8-SOIC package. It integrates interpolation, 1-bit D/A conversion, and output analog filtering within a compact form factor. The device supports serial data interfaces and operates on a single +5 V power supply. Key electrical specifications include 18-bit resolution, a dynamic range of 94 dB, and a total harmonic distortion of 0.003%. It features low clock jitter sensitivity, linear phase filtering, and on-chip digital de-emphasis capabilities for high-fidelity audio reproduction.

Digital To Analog Converters Feature Summary

• Integrates complete stereo DAC system with interpolation, D/A conversion, and analog output filtering
• Supports on-chip digital de-emphasis and linear phase filtering for signal integrity
• Designed for low clock jitter sensitivity to maintain audio quality
• Operates from a single positive voltage power supply

Digital To Analog Converters Applications

• Digital audio playback systems requiring line-level outputs
• Consumer electronics utilizing 18-bit audio processing
• Compact audio equipment constrained by 8-pin packaging

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Review official datasheets for pinout compatibility and thermal requirements. Ensure supply chain stability as end-of-life notices may affect long-term procurement planning.

Digital To Analog Converters Selection Notes

Select this component when an integrated solution combining interpolation and filtering is required in an 8-pin footprint. Compare against the CS4330 and CS4331 if interface format differences are critical. Evaluate power supply requirements against the specified +5 V operation. Consider the 18-bit resolution limit when designing for higher fidelity applications compared to 24-bit alternatives.

Digital To Analog Converters Part Context

The CS4333 belongs to the Cirrus Logic CS433x family of stereo DACs, which share similar internal architectures but differ primarily in supported serial interface formats. This specific part number denotes the version optimized for particular digital audio stream protocols. It serves as a cost-effective alternative to higher-resolution models while maintaining essential audio performance metrics for standard definition audio applications.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same series include the CS4330 and CS4331, provided their specific serial interface requirements match the system design. Verify that interface protocol differences do not necessitate firmware or hardware modifications during replacement.
