CS4352-CZZ

ADCs/DACs - Special Purpose Overview

The CS4352-CZZ is a stereo digital-to-analog converter (DAC) from Cirrus Logic, designed for high-fidelity audio applications. It features a fifth-order multi-bit delta-sigma modulator with 24-bit resolution and supports sample rates up to 192 kHz. The device integrates digital interpolation, de-emphasis, analog filtering, and a line driver capable of delivering 2 Vrms into a 5 kΩ AC load. Key performance metrics include a typical dynamic range of 106 dB (A-weighted) and -93 dB THD+N. It operates on separate power supplies: +3.3 V core, +9 to 12 V analog, and +1.5 to 3.3 V interface. The component is housed in a lead-free 20-pin TSSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CZZ' corresponds to the Commercial grade (-40°C to +85°C) variant as defined in the datasheet. Ensure that the ordering information section of the official document is consulted for current availability status and exact packaging details, as distribution data may vary.

ADCs/DACs - Special Purpose Selection Notes

Select this component for cost-sensitive stereo audio systems requiring integrated filtering and line driving capabilities. Ensure the design accommodates the required three power supply rails (+3.3 V, +9-12 V, +1.5-3.3 V). Verify that the serial audio interface format (I²S, Left/Right Justified) matches the source processor via DIF pin configuration.

ADCs/DACs - Special Purpose Part Context

The CS4352 is part of Cirrus Logic's stereo DAC family, distinguished by its complete system integration including digital filters and analog outputs. It utilizes a multi-bit delta-sigma architecture to achieve high dynamic range and low distortion without external resistor matching errors. The device is available in both Commercial and Automotive grades, with the CZZ suffix denoting the commercial temperature range.
