CS5343-CZZR

ADCs/DACs - Special Purpose Overview

The CS5343-CZZR is a stereo analog-to-digital converter from Cirrus Logic, utilizing a 3rd-order multi-bit Delta-Sigma architecture. It provides 24-bit resolution with a dynamic range of 98 dB at 5 V and supports audio sample rates up to 108 kHz per channel. The device integrates anti-alias filtering and high-pass filters for DC offset removal, eliminating the need for external components. It operates on a single +3.3 V or +5 V supply with power consumption under 40 mW at 3.3 V. The unit is housed in a 10-pin TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Advanced 3rd-order multi-bit Delta-Sigma modulation for high fidelity
• Supports I²S serial audio format with master or slave operation
• Slave mode speed auto-detect for sample rates from 4 kHz to 108 kHz
• High-impedance sampling network reduces external component count

ADCs/DACs - Special Purpose Applications

• Set-top boxes
• DVD-karaoke players
• DVD recorders
• A/V receivers
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the -CZZR suffix indicates the commercial grade (-40°C to +85°C) variant packaged in tape and reel. Confirm that the specific application requires the I²S interface, as the CS5344 model supports Left-Justified format instead. Ensure power supply decoupling follows the recommended layout to maintain specified performance levels.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring low-latency digital filtering and negligible distortion. The CS5343 is suitable for applications needing a single-ended analog input with an input impedance of 7.5 MΩ. Consider the CS5344 if Left-Justified audio format compatibility is required rather than I²S.

ADCs/DACs - Special Purpose Part Context

This part belongs to the CS5343/4 family of audio A/D converters. The CS5343 specifically outputs data in I²S format, while the CS5344 uses Left-Justified format. Both share identical electrical characteristics and packaging options, differing only in the serial audio interface protocol.
