CS4392K-KZZR

ADCs/DACs - Special Purpose Overview

The CS4392K-KZZR is a 24-bit, 192 kHz stereo digital-to-analog converter (DAC) from Cirrus Logic. It integrates interpolation, fifth-order delta-sigma D/A conversion, digital de-emphasis, volume control, channel mixing, and analog filtering. The device supports PCM data at sample rates from 4 kHz to 192 kHz and Direct Stream Digital (DSD) audio. Key electrical specifications include an 114 dB dynamic range and 100 dB THD+N. It operates on a single +5 V supply with logic levels ranging from 5 V to 1.8 V. The component is housed in a 20-pin TSSOP package.

• Volume control with 1 dB step size, soft ramp, and zero-crossing transitions
• Direct interface with 5 V to 1.8 V logic via I2C or SPI control port

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix KZZR indicates reel packaging for the 20-pin TSSOP variant. Confirm the operating temperature range of -10°C to +70°C matches the design requirements. Ensure the power supply voltage remains within the specified limits for stable operation.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-resolution audio processing with integrated volume control. It is pin and register compatible with the CS4391, facilitating performance upgrades. Consider the available oversampling modes (Single, Double, Quad Speed) when designing the clocking architecture.

ADCs/DACs - Special Purpose Part Context

The CS4392K-KZZR belongs to the CS4392 series of audio DACs. It serves as a complete solution for stereo audio output, combining digital signal processing with analog conversion. The part is designed to replace older discrete solutions by integrating necessary filtering and control functions into a single IC.

ADCs/DACs - Special Purpose Replacement Considerations

The CS4391 is pin and register compatible with the CS4392, allowing for direct substitution if performance requirements align. Verify that any replacement maintains the required 24-bit resolution and 192 kHz support capabilities.
