CS4272-CZZR
Overview
The CS4272-CZZR is a high-performance 24-bit, 192 kHz stereo audio CODEC integrating dual analog-to-digital and digital-to-analog converters. It utilizes a differential architecture and sigma-delta modulation to provide high-fidelity audio conversion with a wide dynamic range and low distortion. The device supports various serial interfaces including I2C and SPI for software control or can be operated in hardware mode.
Why Choose This Part
This CODEC provides excellent dynamic range and low noise floor using differential signal paths, making it suitable for professional audio applications. It offers flexible power management with a 3.3V or 5V digital interface and a dedicated 5V analog supply to ensure signal integrity. The 28-TSSOP package allows for a compact footprint while maintaining 24-bit resolution across two channels.
Applications
Key Specifications
Getting Started
To evaluate this part, designers often use the CDB4272 customer demonstration board which provides access to all pins and easy interfacing via headers. Ensure the analog supply (VA) is maintained between 4.75V and 5.25V for specified performance, and decouple all power pins with low-ESR capacitors close to the device. Software control is available via I2C or SPI for configuring internal registers and digital filters.
