CS4224-KSZR

Codecs Overview

The CS4224-KSZR is a 24-bit stereo audio codec manufactured by Cirrus Logic Inc. It integrates stereo analog-to-digital and digital-to-analog converters using delta-sigma conversion techniques. The device operates from a single +5 V power supply with a digital interface voltage range of 2.7 V to 5 V. Key electrical specifications include a typical dynamic range of 105 dB for both ADC and DAC, and a DAC signal-to-noise ratio of 110 dB (EIAJ). It features an analog volume control capable of 113.5 dB attenuation in 0.5 dB steps. The component supports serial audio data interfaces and includes on-chip anti-aliasing and output smoothing filters.

Codecs Feature Summary

• Integrates stereo A/D and D/A converters with 24-bit resolution
• Includes analog volume control with soft ramping or zero crossing techniques
• Supports selectable de-emphasis filters for 32, 44.1, and 48 kHz sample rates
• Features differential inputs and outputs with on-chip filtering

Codecs Applications

• Digital effects processors
• Digital Audio Tape (DAT) recorders
• Multitrack recorders

Codecs Procurement Notes

Verify the specific suffix 'KSZR' against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure compatibility with the required control port interface, as the CS4224 supports both SPI and I2C modes. Confirm that the single +5 V supply requirement aligns with the target system design before finalizing procurement.

Codecs Selection Notes

Select the CS4224-KSZR when analog volume control is required, distinguishing it from the CS4223 variant which lacks this feature. Ensure the application utilizes a single +5 V analog supply and a compatible digital logic level between 2.7 V and 5 V. Verify that the 28-pin SSOP package fits the PCB layout constraints and that the commercial temperature range (-10°C to +70°C) meets operational requirements.

Codecs Part Context

The CS4224 is part of the CS4223/CS4224 family of high-performance audio codecs from Cirrus Logic. While the CS4223 provides identical conversion capabilities, the CS4224 adds an integrated analog volume control section. Both devices share the same core delta-sigma architecture and pinout structure, differing primarily in the inclusion of the attenuator circuitry within the CS4224.

Codecs Replacement Considerations

The CS4223-KSZR is a functional substitute if analog volume control is not needed. For industrial temperature ranges, consider the CS4224-BS or CS4224-DS variants. Verify pin compatibility and register mapping when substituting.
