Use a 10uF capacitor in parallel with a 100nF capacitor, placed as close as possible to the power pins, to ensure proper decoupling and noise reduction.
Set the MCLK pin to the desired clock frequency, and ensure the BCLK and LRCLK pins are connected to the corresponding clock signals. Refer to the datasheet for specific pin configurations.
Keep analog and digital signals separate, use a ground plane, and route analog signals away from digital signals. Use a star topology for analog signals and avoid crossing digital signals over analog signals.
Check the analog input signal level, ensure proper gain staging, and verify the clock and data signals. Use an oscilloscope to inspect the analog input and digital output signals.
While the CS4272-CZZR can operate with a 2.5V to 3.6V supply, it's recommended to use the specified 3.3V for optimal performance and to ensure compatibility with other components.
