Digital To Analog Converters Procurement Notes

This component is officially listed as obsolete and has been discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturing orders. Buyers must confirm the specific revision status and ensure compliance with RoHS3 standards before acquisition. Supply chain reliability may vary significantly due to the end-of-life status.

Digital To Analog Converters Selection Notes

Designers seeking a replacement should consider that this part is no longer in production. Alternative selection criteria should prioritize components with compatible 8-pin SOIC footprints and similar 5V operating requirements. Verify that substitute devices support the required 24-bit resolution and 96 kHz sampling rate. Ensure new selections maintain I2S interface compatibility to preserve existing system architectures without significant redesign.

Digital To Analog Converters Part Context

The CS4334 series represents Cirrus Logic's legacy line of stereo audio DACs designed for general-purpose audio applications. This specific variant belongs to the broader family of delta-sigma converters known for their simplicity and effective noise shaping. The 8-SOIC packaging was selected for cost-effective surface-mount assembly in compact consumer and professional audio devices during its active production period.

Digital To Analog Converters Replacement Considerations

Public documentation confirms the CS4334-KSZR as a verified substitute part number within the same product family. Other potential replacements include the CS4335, CS4338, and CS4339, which offer similar functionalities but may differ in pinout or performance specifications. Always verify electrical compatibility and mechanical footprint alignment when transitioning to these alternatives.
