CS43122-KSZ

ADCs/DACs - Special Purpose Overview

The CS43122-KSZ is a 24-bit, 192 kHz stereo digital-to-analog converter (DAC) from Cirrus Logic. It utilizes a multi-bit delta-sigma architecture with second-order dynamic-element matching to achieve a typical dynamic range of 122 dB and -102 dB THD+N. The device operates on a single +5 V supply and supports sample rates up to 192 kHz. Key features include soft mute control, digital de-emphasis for 32, 44.1, and 48 kHz, and an external reference input. It is housed in a 28-pin SOIC package.

• Single +5 V power supply operation

ADCs/DACs - Special Purpose Applications

• Universal DVD players
• A/V receivers
• Outboard D/A converters
• CD players
• Mixing consoles

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KSZ' against the manufacturer's current ordering information to confirm pinout compatibility and temperature range specifications. Ensure that the 28-pin SOIC package dimensions match the target PCB footprint requirements before finalizing procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high-fidelity audio conversion with a single +5 V supply. Consider the 122 dB dynamic range and low jitter sensitivity for professional audio systems. Verify interface compatibility with the host processor's serial data format and clocking requirements.

ADCs/DACs - Special Purpose Part Context

The CS43122 is part of Cirrus Logic's high-performance audio DAC family. It is designed as a drop-in replacement for legacy components like the CS4396 due to pin compatibility. The device integrates a digital interpolation filter and a switched capacitor DAC/low-pass filter.

ADCs/DACs - Special Purpose Replacement Considerations

The datasheet explicitly states that the CS43122 is pin-compatible with the CS4396. Designers should verify electrical parameter differences between these two parts when performing direct replacements.
