CS4398K-CZZ

ADCs/DACs - Special Purpose Overview

The CS4398K-CZZ is a stereo 24-bit/192 kHz digital-to-analog converter (DAC) from Cirrus Logic, housed in a 28-pin TSSOP package. It utilizes an advanced multibit Delta-Sigma architecture to achieve a dynamic range of 120 dB and a total harmonic distortion plus noise (THD+N) of -107 dB. The device supports PCM data at sample rates up to 216 kHz and includes Direct Stream Digital (DSD) processing with a dedicated on-chip 50 kHz filter. Key features include selectable digital interpolation filters, half-dB step volume control with soft ramping, and embedded level translators for 1.8 V to 5 V serial audio and control interfaces.

ADCs/DACs - Special Purpose Feature Summary

• Advanced Multibit Delta-Sigma Architecture: Delivers 120 dB dynamic range and -107 dB THD+N with low clock jitter sensitivity.
• PCM and DSD Support: Accepts PCM data up to 216 kHz and processes DSD audio via a proprietary processor or direct path.
• Integrated Volume Control: Features half-dB step size adjustment with soft ramp functionality for both PCM and DSD modes.
• Flexible Interface Configuration: Supports standalone hardware configuration or I²C/SPI control ports with embedded 1.8 V to 5 V level translators.

ADCs/DACs - Special Purpose Procurement Notes

Verify the 'K' suffix indicates the rail container format as specified in the ordering information. Confirm that the commercial temperature grade (-10°C to +70°C) meets system requirements. Ensure power supply decoupling and grounding layouts adhere to the typical connection diagram to maintain specified analog performance characteristics.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring high-fidelity stereo conversion with integrated DSD support. Choose the standalone mode for simple hardware-controlled applications or the control port mode for complex routing and mixing configurations. Ensure the host system provides appropriate master clock ratios and voltage levels compatible with the 1.8 V to 5.25 V operating ranges.

ADCs/DACs - Special Purpose Part Context

The CS4398K-CZZ is part of the CS4398 family, distinguished by its 28-pin TSSOP packaging and rail container type. It serves as a complete stereo DAC solution, integrating digital filtering, modulation, and analog output stages. The device is designed for high-performance audio systems where low distortion and wide dynamic range are critical specifications.
