CS43198-CNZ

Digital To Analog Converters Overview

The CS43198-CNZ is a high-performance stereo audio digital-to-analog converter (DAC) manufactured by Cirrus Logic. It features a 32-bit resolution and utilizes delta-sigma architecture to deliver superior audio fidelity. The device supports sampling frequencies up to 384 kHz and includes an integrated DirectStream Digital processor for DSD playback. Key electrical specifications include a dynamic range of 130 dB and a THD+N rating of -115 dB. It operates on a single supply voltage ranging from 1.66 V to 1.94 V. The component is housed in a 40-pin QFN package with dimensions of 5x5 mm, designed for surface mount installation.

Digital To Analog Converters Feature Summary

• MasterHIFI Audio certification ensuring high-fidelity standards including high dynamic range and low distortion
• Integrated DirectStream Digital processor supporting DSD256 playback with seamless switching between PCM and DSD streams
• Advanced 32-bit oversampling multi-bit modulator with mismatch shaping technology to eliminate distortion caused by internal component variations

Digital To Analog Converters Applications

• High-end portable audio players requiring low power consumption and high performance
• Desktop hi-fi audio systems demanding precise digital-to-analog conversion
• Professional audio interfaces utilizing I2S or TDM serial audio inputs

Digital To Analog Converters Procurement Notes

Verify the specific suffix CNZ indicates the 40-QFN package variant when sourcing. Confirm RoHS compliance status through official manufacturer certificates. Check moisture sensitivity level requirements during storage and handling. Ensure the ordering quantity matches the standard tray packaging configuration provided by distributors.

Digital To Analog Converters Selection Notes

Select this model for designs prioritizing ultra-low noise and high channel separation. Compare against the CWZR variant if a smaller WLCSP footprint is required instead of the QFN form factor. Consider the integrated headphone driver capabilities if direct drive applications are necessary without external amplification stages.

Digital To Analog Converters Part Context

This component belongs to the CS431xx series of high-performance DACs from Cirrus Logic. It is part of the MasterHIFI product line, which signifies adherence to strict audio quality thresholds. The CS43198-CNZ specifically denotes the QFN package version, distinct from other pinout or footprint variants within the same functional family.

Digital To Analog Converters Replacement Considerations

The PCM5122 and PCM5242 are identified as suitable alternative components. These TI devices offer comparable functionality but may require interface adjustments. Verify pin compatibility and register settings before implementing any substitution in existing hardware designs.
