CS4353-CZZ

ADCs/DACs - Special Purpose Overview

The CS4353-CZZ is a stereo digital-to-analog converter (DAC) from Cirrus Logic, housed in a 24-pin QFN package. It features a fifth-order multi-bit delta-sigma modulator with 24-bit resolution and supports sample rates up to 192 kHz. The device delivers a 106 dB A-weighted dynamic range and -93 dB THD+N. It operates on a single +3.3 V supply for analog and core logic, utilizing an integrated step-up/inverting charge pump to generate internal rails. The interface supply ranges from +0.9 V to +3.3 V. Key specifications include selectable 1 V or 2 V RMS full-scale output levels and low clock-jitter sensitivity.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator architecture providing 106 dB dynamic range and -93 dB THD+N
• Integrated step-up and inverting charge pumps enabling ground-centered analog outputs without DC-blocking capacitors
• Supports serial audio interfaces including I²S and Left-Justified formats with auto-speed mode detection
• Selectable full-scale output amplitude of 1 V RMS or 2 V RMS via hardware pin control

ADCs/DACs - Special Purpose Applications

• Video game consoles
• DVD players and recorders
• A/V receivers and set-top boxes
• Digital TVs and mini-component systems
• Mixing consoles

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CZZ' corresponds to the TSSOP-20 package variant when sourcing, as the primary datasheet references the 'CNZ' QFN-24 package. Confirm lead-free assembly status and humidity sensitivity等级 (MSL) requirements during storage and handling. Ensure the supplier provides valid RoHS compliance documentation matching the component's environmental standards.

ADCs/DACs - Special Purpose Selection Notes

Select this component for cost-sensitive stereo audio systems requiring high dynamic range from a single 3.3 V supply. The integrated charge pump eliminates external bootstrap components, reducing board space. Ensure the design accommodates the pseudo-differential output topology by connecting AOUT_REF to AGND if common-mode noise rejection is not required. Verify that the host processor supports the selected serial interface format (I²S or Left-Justified).

ADCs/DACs - Special Purpose Part Context

The CS4353 belongs to Cirrus Logic's line of complete stereo digital-to-analog systems. It integrates digital interpolation, de-emphasis filtering, and analog output drivers. The device is designed to minimize external component count while maintaining high audio fidelity through its multi-bit delta-sigma modulation technique, which offers ideal differential linearity and tolerance to clock jitter.
