CS4340-CZZR

ADCs/DACs - Special Purpose Overview

The CS4340-CZZR is a stereo digital-to-analog converter (DAC) from Cirrus Logic, designed for high-fidelity audio applications. It integrates digital interpolation, fourth-order delta-sigma conversion, digital de-emphasis, and switched-capacitor analog filtering. The device operates on a +3.0 V or +5.0 V power supply and supports sampling rates up to 96 kHz with 24-bit resolution. Key performance metrics include a dynamic range of 101 dB and total harmonic distortion plus noise (THD+N) of -91 dB. It features Popguard technology to suppress clicks and pops during power transitions.

ADCs/DACs - Special Purpose Feature Summary

• 24-bit resolution with 96 kHz maximum sampling rate
• Integrated fourth-order delta-sigma DAC architecture
• On-chip digital de-emphasis for 32, 44.1, and 48 kHz
• Popguard technology for output protection

ADCs/DACs - Special Purpose Applications

• High-fidelity audio systems
• Home theater receivers
• Professional audio equipment

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CZZR' against official Cirrus Logic documentation to confirm package type and tape-and-reel configuration. Check current lifecycle status as older audio DAC models may be discontinued or subject to product change notifications. Ensure compatibility with existing PCB footprints if replacing legacy components.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a 24-bit, 96 kHz stereo DAC with integrated analog filtering is required. The CS4340-CZZR is suitable for designs needing low clock jitter sensitivity and filtered line-level outputs. Compare against the CS4340A if higher 192 kHz sampling rates are necessary, as the standard CS4340 is limited to 96 kHz.

ADCs/DACs - Special Purpose Part Context

The CS4340-CZZR belongs to the CS4340 family of stereo DACs. It shares core specifications with variants like the CS4340-KS and CS4340-CZZ, differing primarily in packaging and reel options. This part represents the standard 24-bit/96 kHz version, distinct from the enhanced CS4340A which supports 192 kHz operation.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements within the same family include CS4340-CZZ and CS4340-KS. For upgraded performance requiring 192 kHz support, consider the CS4340A series, though verification of interface and power requirements is essential.
