CS4341-KSZ

ADCs/DACs - Special Purpose Overview

The CS4341-KSZ is a stereo digital-to-analog converter (DAC) from Cirrus Logic, housed in a 16-pin SOIC package. It supports audio sample rates from 4 kHz to 100 kHz with a 24-bit resolution. The device operates on a single power supply ranging from 2.7 V to 5.5 V. Key electrical specifications include a dynamic range of up to 101 dB and a total harmonic distortion plus noise (THD+N) of -91 dB at 0 dBFS. Power consumption is specified as 33 mW with a 3.0 V supply.

ADCs/DACs - Special Purpose Feature Summary

• Integrated fourth-order Delta-Sigma DAC architecture with digital interpolation and switched capacitor analog filtering.
• Digital volume control featuring soft ramp, zero-crossing transitions, and 94 dB attenuation capability.
• On-chip digital de-emphasis filters for 32, 44.1, and 48 kHz sample rates.
• Popguard® technology designed to eliminate clicks and pops during power-up and power-down sequences.

ADCs/DACs - Special Purpose Applications

• DVD players
• CD players
• Set-top boxes
• Automotive audio systems

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KS' corresponds to the 16-pin SOIC package variant when sourcing replacements. Confirm that the operating temperature range meets the requirement of -10°C to +70°C. Ensure the design accommodates the required MCLK frequencies and serial interface timing constraints defined in the datasheet.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring low clock-jitter sensitivity and filtered line-level outputs. The internal serial clock mode simplifies system clocking if external SCLK generation is not feasible. Verify compatibility with I²C or SPI control port interfaces for volume and mode configuration.

ADCs/DACs - Special Purpose Part Context

The CS4341-KSZ belongs to the CS4341 family of high-performance stereo DACs. It shares architectural similarities with the CS4340 but includes integrated digital volume control and Popguard® transient management features not present in all related models.

ADCs/DACs - Special Purpose Replacement Considerations

The CS4341-KS is the standard equivalent part number for the CS4341-KSZ. Both utilize the 16-pin SOIC package and share identical functional specifications.
