CS4353-DZZ

ADCs/DACs - Special Purpose Overview

The CS4353-DZZ is a stereo audio digital-to-analog converter (DAC) from Cirrus Logic, housed in a 24-pin QFN package. It operates on a single +3.3 V supply and features an integrated step-up/inverting charge pump to generate internal rails for ground-centered analog outputs. The device supports 24-bit resolution with sample rates up to 192 kHz via I²S or Left-Justified serial interfaces. Key electrical specifications include a 106 dB A-weighted dynamic range, -93 dB THD+N, and selectable full-scale output voltages of 1 VRMS or 2 VRMS. Operating temperatures range from -40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator architecture providing ideal differential linearity and high tolerance to clock jitter.
• Integrated charge pump eliminates the need for external DC-blocking capacitors by enabling ground-centered outputs.
• Selectable full-scale output amplitude: 1 VRMS or 2 VRMS via the 1_2VRMS pin.
• Supports I²S and Left-Justified digital audio formats with auto-detection for Single, Double, and Quad-speed modes.

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 'DZZ' against the manufacturer's current ordering information, as datasheets may list variants like CNZ or CNZR. Confirm lead times and availability through authorized distributors, as component status can change. Ensure compliance with RoHS and REACH regulations relevant to the manufacturing batch.

ADCs/DACs - Special Purpose Selection Notes

Select this component for cost-sensitive stereo audio applications requiring low external component count. Ensure the design accommodates the required MCLK frequencies (up to 51.2 MHz) and provides adequate decoupling for the charge pump capacitors. Verify that the interface voltage (VL) matches the host processor logic levels within the 0.9 V to 3.3 V range.

ADCs/DACs - Special Purpose Part Context

The CS4353 belongs to Cirrus Logic's line of 3.3 V stereo audio DACs. It is designed for consumer electronics where space and power efficiency are critical. The device integrates digital interpolation, de-emphasis, and analog filtering, reducing the bill of materials compared to discrete solutions.

ADCs/DACs - Special Purpose Replacement Considerations

Check for updated revisions or alternative packages from Cirrus Logic. Cross-reference with similar models in the CS43xx series if pin compatibility or specific performance metrics differ. Verify that any substitute maintains the same 24-pin QFN footprint and thermal pad requirements.
