CS4272
Overview
The CS4272 from Cirrus Logic is an integrated audio codec family combining analog-to-digital and digital-to-analog conversion for multi-channel audio. It is intended as a drop-in codec solution for evaluation and OEM designs where a single-chip ADC/DAC reduces BOM and board complexity. The device is commonly used as the audio front end in consumer and professional audio systems.
Why Choose This Part
Choosing an integrated codec like the CS4272 reduces discrete component count by providing both ADC and DAC functionality in one package, simplifying PCB layout and clocking. As a widely used codec family, it has established evaluation boards and community examples, making it easier to prototype and validate audio paths before production.
Applications
Key Specifications
Getting Started
Begin with the manufacturer's evaluation board or a third-party breakout/eval board for the CS4272 family to verify signal routing and levels. Host control and audio streaming are typically handled by an MCU or DSP with a digital audio interface; use your preferred MCU toolchain (GCC, Keil, IAR) or DSP development environment to configure the codec via its control interface and stream audio data.
