CS4353-CNZ

ADCs/DACs - Special Purpose Overview

The CS4353-CNZ is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic. It operates on a single 3.3V supply and features an integrated line driver capable of delivering a 2 Vrms output into a 5 kΩ AC load. The device utilizes a multi-bit delta-sigma modulation architecture with 24-bit resolution, supporting sample rates up to 96 kHz. Key electrical specifications include a dynamic range of 106 dB (A-weighted) and a total harmonic distortion plus noise (THD+N) of -93 dB. It employs a serial interface for digital input and is housed in a 24-pin QFN package.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 2 Vrms line-level driver eliminating external components
• Multi-bit delta-sigma modulator for high linearity and jitter tolerance
• Low-latency digital filtering supports standard audio sample rates
• Popguard technology controls clicks and pops during power transitions

ADCs/DACs - Special Purpose Applications

• Set-top boxes
• Digital TVs
• Blu-ray disc players
• DVD players

ADCs/DACs - Special Purpose Procurement Notes

The CS4353-CNZ is listed as End-of-Life (EOL) by the manufacturer. Distribution channels indicate restricted availability or discontinuation status. Verification of current stock levels and valid replacement part numbers from authorized distributors is required before procurement planning.

ADCs/DACs - Special Purpose Selection Notes

This component is suitable for designs requiring a low-component-count stereo DAC with integrated analog output drivers. It requires a 3.3V core supply and supports I2S serial interfaces. Designers should verify that the 96 kHz maximum sample rate meets application requirements, as higher-performance variants like the CS4352 support 192 kHz.

ADCs/DACs - Special Purpose Part Context

The CS4353 belongs to the Cirrus Logic CS43xx series of stereo audio DACs. It shares architectural similarities with the CS4354 but differs in supply voltage requirements; the CS4353 uses a single 3.3V supply, whereas the CS4354 typically requires a 5V analog supply with an internal charge pump. Both devices target consumer audio electronics.

ADCs/DACs - Special Purpose Replacement Considerations

The CS4353-CNZR is the tape-and-reel version of the same component. For pin-compatible alternatives with similar specifications, the CS4354 may be considered if the system can accommodate its specific power supply requirements.
