CS43198-CWZR

Digital To Analog Converters Overview

The CS43198-CWZR is a stereo audio digital-to-analog converter (DAC) from Cirrus Logic, featuring 32-bit resolution and a delta-sigma architecture. It operates within an analog and digital supply voltage range of 1.66V to 1.94V. The device provides two converters with differential voltage outputs in a 42-WLCSP package measuring 3.18x2.71 mm. Key performance metrics include a dynamic range of 130 dB and THD+N of -115 dB. It supports I2S interfaces and functions within a temperature range of -10°C to 70°C.

Digital To Analog Converters Feature Summary

• Supports up to 384 kHz sampling frequency and DSD256 playback via integrated DirectStream Digital processor
• Includes five selectable digital filter responses to minimize pre-ringing and transient overshoot
• Features advanced 32-bit oversampling multi-bit modulator with mismatch shaping technology
• Offers soft ramp volume control with 0.5 dB steps and automatic mute detection

Digital To Analog Converters Applications

• High-fidelity desktop CD players
• Portable audio devices requiring low power consumption
• Home theater systems demanding high dynamic range

Digital To Analog Converters Procurement Notes

Verify the specific suffix CWZR against official datasheets to confirm the WLCSP package type and pinout compatibility. Ensure that ordering quantities align with manufacturer reel specifications. Confirm RoHS compliance status for current production batches before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a compact WLCSP footprint is required alongside high-performance audio metrics. Compare the 42-pin WLCSP variant against the 40-QFN alternative based on available board space constraints. Verify interface compatibility with I2S sources and ensure supply voltage requirements match the system design.

Digital To Analog Converters Part Context

This part belongs to the CS431xx series of high-performance DACs designed for MasterHIFI audio applications. The series emphasizes system-level audio performance while minimizing battery drain in portable devices. The CS43198 specifically targets designs requiring direct DSD processing and high channel isolation.

Digital To Analog Converters Replacement Considerations

Publicly documented substitutes include PCM5122 and PCM5242. These alternatives lack direct cross-reference equivalence but serve as functional options for similar audio conversion needs.
