CS43198-CNZR

Digital To Analog Converters Overview

The CS43198-CNZR is a high-performance stereo digital-to-analog converter manufactured by Cirrus Logic Inc. It features a 32-bit resolution and utilizes delta-sigma architecture to deliver superior audio fidelity. The device supports I2S data interfaces and provides differential voltage outputs without internal buffering. It operates within an analog and digital supply voltage range of 1.66V to 1.94V. Packaged in a 40-QFN (5x5) surface-mount format, it is designed for professional audio applications requiring low power consumption and high dynamic range performance.

Digital To Analog Converters Feature Summary

• Supports MasterHIFI™ Audio technology for enhanced sound quality
• Integrates both external and internal reference capabilities
• Features differential output configuration for noise immunity

Digital To Analog Converters Applications

• Professional audio equipment
• High-fidelity home theater systems
• Digital audio workstations

Digital To Analog Converters Procurement Notes

Verify the specific suffix CNZR to confirm the 40-QFN package type and tape-and-reel packaging format. Ensure compatibility with the required 1.66V to 1.94V supply rails during design validation. Confirm RoHS3 compliance status if environmental regulations apply to the target market. Cross-reference the manufacturer part number with distributor codes to avoid ordering errors.

Digital To Analog Converters Selection Notes

Select this component when a stereo DAC with 32-bit resolution and differential outputs is required. Compare against the CWZR variant if a smaller WLCSP package is preferred over the QFN form factor. Consider the CS43131 if single-ended outputs are acceptable to reduce complexity. Verify that the I2S interface matches the source processor's digital audio standards.

Digital To Analog Converters Part Context

This component belongs to the CS43198 series of high-performance audio DACs from Cirrus Logic. It shares architectural similarities with other members like the CS43131 but differs in output configuration and feature set. The CNZR suffix specifically denotes the quad flat no-lead package variant, distinguishing it from wafer-level chip-scale packages used in other models within the same product family.

Digital To Analog Converters Replacement Considerations

The CS43198-CWZR serves as a pin-compatible alternative offering the same electrical specifications but in a 42-WLCSP package. Designers must account for the physical footprint differences between the 40-QFN and 42-WLCSP formats when substituting parts.
