CS4330-KSR

Digital To Analog Converters Overview

The CS4330-KSR is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It integrates interpolation, 1-bit D/A conversion, and output analog filtering within an 8-pin package. The device features 18-bit resolution and supports serial input loading. It operates on a single +3 V or +5 V power supply. Key electrical parameters include a dynamic range of 94 dB and total harmonic distortion (THD) of 0.003%. The component includes linear phase filtering and on-chip digital de-emphasis capabilities.

Digital To Analog Converters Feature Summary

• Complete stereo DAC system with integrated interpolation and analog filtering
• Low clock jitter sensitivity for stable audio performance
• On-chip digital de-emphasis functionality

Digital To Analog Converters Applications

• Digital audio playback systems

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Cirrus Logic Inc., noting prior corporate history as Crystal Semiconductor Corp. Confirm the specific suffix KSR corresponds to the required packaging and tape-and-reel configuration. Ensure compatibility with the specified serial interface format before procurement.

Digital To Analog Converters Selection Notes

Select this component for applications requiring 18-bit resolution and low THD in an 8-pin form factor. Verify that the system design accommodates the single +3 V or +5 V supply requirement. Check if the 94 dB dynamic range meets the specific audio fidelity needs of the target application.

Digital To Analog Converters Part Context

This part belongs to the CS433x family of stereo DACs from Cirrus Logic. It shares architectural similarities with the CS4331 and CS4333 models, differing primarily in the supported serial interface formats. All variants utilize the same 8-pin package and core conversion technology.

Digital To Analog Converters Replacement Considerations

Direct replacements include the CS4331 and CS4333 models from the same product family. These alternatives offer identical core performance but may require verification of serial interface protocol compatibility with the host system.
