Power Supply: Ensure the power supply voltage is within the specified range of 1.8V to 3.6V. Use appropriate decoupling capacitors close to the power pins.
Analog Inputs: Connect differential analog audio signals to the input pins ensuring they do not exceed ±0.5V.
Digital Configuration: Configure the digital interface settings via control registers according to the desired format (I2S, Left-justified, etc.).
Sampling Rate Setting: Set the sampling frequency as per application requirements using the provided register settings.
Grounding and Layout: Pay attention to proper grounding and PCB layout practices to minimize noise and ensure optimal performance.
Initialization: Initialize the device by writing to its configuration registers through the I2C or SPI interface before starting operation.
Power Management: Manage power modes effectively to balance power consumption and performance, especially in battery-operated devices.
