Getting Started

To evaluate the CS4272, engineers should utilize the CDB4272 evaluation board which provides a reference layout and easy access to I2C/SPI control headers. Communication is typically handled via the Serial Audio Interface (I2S or Left-Justified) for data and I2C/SPI for software configuration of registers such as volume control and filter selection.
