CS4392-KSR

Digital To Analog Converters Overview

The CS4392-KSR is a stereo digital-to-analog converter (DAC) manufactured by Cirrus Logic, featuring a 24-bit resolution and support for sample rates up to 192 kHz. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes a serial interface. The component is housed in a 20-pin SOIC package and is designed for surface mount installation. It functions across an operating temperature range from -10°C to +70°C.

Digital To Analog Converters Feature Summary

• Complete stereo DAC system architecture incorporating digital interpolation, fifth-order delta-sigma conversion, and analog output filtering.
• Integrated volume control functionality with soft ramp capabilities, 1 dB step size, and zero-crossing click-free transitions.
• Supports Direct Stream Digital (DSD) mode and includes selectable digital filters with fast and slow roll-off options.

Digital To Analog Converters Applications

• DVD players
• A/V receivers
• CD players
• Set-top box systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'KSR' against official manufacturer documentation, as standard listings often reference 'KS' or 'KZZR'. Confirm current lifecycle status, as this series may be discontinued or subject to limited availability. Ensure pin compatibility with existing designs if substituting from other variants like CS4391.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high dynamic range and low clock jitter sensitivity. Verify that the host logic levels are compatible with the specified 5 V to 1.8 V direct interface range. Ensure the design accommodates the single +5 V power supply requirement and the thermal characteristics of the SOIC-20 package.

Digital To Analog Converters Part Context

The CS4392 belongs to the Cirrus Logic CS4392 series of audio DACs. It is pin-compatible with the CS4391 model, allowing for potential design upgrades without layout changes. The device integrates mixing functions and digital de-emphasis, positioning it as a complete solution for high-fidelity audio playback systems.

Digital To Analog Converters Replacement Considerations

The CS4391 is documented as pin-compatible with the CS4392 series. Other Cirrus Logic models such as CS4392-KS or CS4392-KZZR share similar core specifications but differ in packaging or termination standards.
