CS4353-DZZR

ADCs/DACs - Special Purpose Overview

The CS4353-DZZR is a stereo digital-to-analog converter (DAC) from Cirrus Logic, housed in a 24-pin QFN package. It operates on a single +3.3 V supply for the analog and core sections, with an interface supply range of +0.9 V to +3.3 V. The device features a fifth-order multi-bit delta-sigma modulator providing 24-bit resolution and supports sample rates up to 192 kHz. Key electrical specifications include a typical dynamic range of 106 dB (A-weighted) and -93 dB THD+N. It integrates an on-chip charge pump to generate internal rails, enabling ground-centered line-level outputs without external DC-blocking capacitors.

ADCs/DACs - Special Purpose Feature Summary

• Multi-bit Delta-Sigma Modulator with 106 dB A-weighted dynamic range
• Integrated step-up/inverting charge pump for ground-centered outputs
• Selectable 1 VRMS or 2 VRMS full-scale output via hardware pin
• Supports I²S and Left-Justified serial audio interfaces

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the DZZR suffix against the manufacturer's current ordering guide, as it may indicate specific tape-and-reel packaging or variant details not explicitly detailed in the base datasheet. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may apply to this component family.

ADCs/DACs - Special Purpose Selection Notes

Select the CS4353-DZZR for cost-sensitive stereo audio applications requiring low power consumption and minimal external components. Ensure the design accommodates the +3.3 V analog supply and the +0.9 V to +3.3 V interface voltage. Verify that the required output amplitude (1 VRMS vs 2 VRMS) matches the system input requirements by configuring the 1_2VRMS pin accordingly.

ADCs/DACs - Special Purpose Part Context

The CS4353 belongs to Cirrus Logic's line of high-performance audio DACs designed for consumer electronics. It replaces older discrete solutions by integrating interpolation filters, de-emphasis, and analog filtering on a single chip. The DZZR suffix typically denotes a reel-packaged version of the standard CS4353, facilitating automated assembly in manufacturing environments.

ADCs/DACs - Special Purpose Replacement Considerations

Direct pin-compatible replacements are limited due to the specific integration of the charge pump and output stage. Review the CS4351 or CS4352 datasheets for similar feature sets, but verify pinout compatibility and supply voltage requirements before substitution.
