CS4352-DZZR

ADCs/DACs - Special Purpose Overview

The CS4352-DZZR is a stereo digital-to-analog converter (DAC) from Cirrus Logic, designed for high-fidelity audio applications. It features a multi-bit delta-sigma modulator with 24-bit resolution and supports sample rates up to 192 kHz. The device integrates a line driver capable of delivering 2 Vrms into a 5 kΩ AC load, achieving a typical dynamic range of 106 dB A-weighted and -93 dB THD+N. It operates with +3.3 V core, +9 to 12 V analog, and +1.5 to 3.3 V interface supplies. The automotive grade (-DZZ) variant functions within an ambient temperature range of -40°C to +105°C and is housed in a 20-pin TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator architecture providing ideal differential linearity and high tolerance to clock jitter.
• Integrated 2 Vrms line-level driver with analog low-pass filter and Popguard® technology for transient control.
• Supports I²S, Left-Justified, and Right-Justified serial audio interfaces with auto-detection of single, double, or quad-speed modes.
• Includes on-chip digital de-emphasis, stereo mute controls, and low-latency digital filtering.

ADCs/DACs - Special Purpose Applications

• Video game consoles
• DVD players and recorders
• A/V receivers and set-top boxes
• Digital televisions
• Mini-component systems and mixing consoles

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix DZZR confirms the automotive temperature rating (-40°C to +105°C). Confirm that the required analog supply voltage (VA_H) falls within the 9 V to 12 V range for optimal performance. Ensure power sequencing follows the recommended RST pin protocol to activate Popguard functionality effectively.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a complete stereo DAC solution with integrated line drivers is required. The -DZZ suffix is necessary for automotive-grade thermal specifications. Verify compatibility with the system's serial audio interface format (I²S, Left, or Right Justified) via DIF pins. Ensure the design can accommodate the separate VA_H supply rail between 9 V and 12 V.

ADCs/DACs - Special Purpose Part Context

The CS4352 belongs to Cirrus Logic's fourth-generation audio DAC family. It is part of a series that includes commercial variants like the CS4352-CZZR and related models such as the CS4353 and CS4354. The device is designed to reduce external component count by integrating interpolation filters, de-emphasis, and analog output stages.
