CS4348-CZZR

ADCs/DACs - Special Purpose Overview

The CS4348-CZZR is a stereo digital-to-analog converter (DAC) from the Cirrus Logic CS4344 family, housed in a 10-pin TSSOP package. It features 24-bit resolution and supports sample rates up to 192 kHz via an automatically detected serial audio interface. The device utilizes a fourth-order multibit delta-sigma modulator with integrated interpolation filtering and switched-capacitor analog output stages. Operating on a single +3.3 V or +5 V supply, it delivers a typical dynamic range of 105 dB and -90 dB THD+N. Key functional attributes include Popguard® technology for transient suppression and on-chip digital de-emphasis.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'CZZR' against current manufacturer documentation to confirm availability status and lead times. Distributor listings may indicate end-of-life status; consult official datasheets for active production confirmation before design-in.

ADCs/DACs - Special Purpose Selection Notes

Select the CS4348 variant specifically when the system requires right-justified 16-bit data alignment. Ensure the host processor can provide the necessary MCLK/LRCK ratios (e.g., 256x, 384x, 1024x) for the desired sample rate. Verify that the application environment temperature falls within the commercial grade range of -10°C to +70°C.

ADCs/DACs - Special Purpose Part Context

The CS4348 is part of the CS4344/5/8 family, distinguished primarily by its supported serial data format. While the CS4344 supports I²S and the CS4345 supports Left Justified formats, the CS4348 is optimized for Right Justified 16-bit data. All members share identical core performance metrics, power requirements, and package dimensions.

ADCs/DACs - Special Purpose Replacement Considerations

Direct functional replacements within the same family include the CS4344 and CS4345, provided the host interface supports their respective data formats (I²S and Left Justified). No other cross-family substitutes are confirmed in the source material.
