CS4220-KSR

Audio Special Purpose Overview

The CS4220-KSR is a highly integrated, high-performance 24-bit stereo audio codec manufactured by Cirrus Logic. It provides stereo analog-to-digital (ADC) and stereo digital-to-analog (DAC) converters using delta-sigma conversion techniques. The device operates from a single +5 V power supply and features a digital interface compatible with 3 V to 5 V logic levels.

Audio Special Purpose Feature Summary

• 24-bit stereo audio codec with 100 dB dynamic range for both ADC and DAC channels
• Operates on a single +5 V power supply with 3-5 V digital interface compatibility
• Includes selectable de-emphasis filters for 32, 44.1, and 48 kHz sample rates
• Features differential inputs/outputs and on-chip anti-aliasing and output smoothing filters

Audio Special Purpose Applications

• Digital audio effectors requiring high-resolution audio processing
• Professional audio equipment utilizing DSP-based architectures
• High-fidelity consumer audio playback systems

Audio Special Purpose Procurement Notes

Verify the package type against the specific suffix; distributor data indicates 'Bulk' packaging for this SKU. Confirm that the +5 V single-supply requirement aligns with the target system design, as the CS4220 requires a +5 V analog supply.

Audio Special Purpose Selection Notes

Select the CS4220-KSR when a single +5 V supply is available and high dynamic range (100 dB) is required for stereo applications. Ensure the host system supports the necessary serial interface modes (Master/Slave) and utilizes the internal crystal oscillator or provides an external clock.
