Power Supply Connections:
- Connect the power supply pins (VDD) to a stable voltage between 2.7V and 5.5V.
- Ensure the digital power supply (VDDIO) is connected to a voltage within the range of 1.8V to 3.6V.
Analog Inputs:
- Connect analog input signals to the appropriate input pins ensuring they do not exceed the supply voltage (VDD).
Standby Mode:
- To enter standby mode, set the STBY pin high. This reduces power consumption to approximately 2μA.
Active Mode:
- Set the STBY pin low to activate the device. The active current will be around 20mA at a typical operating condition.
Sampling Configuration:
- Configure the sampling frequency as required, supporting up to 192kHz for high-quality audio applications.
Signal Processing:
- Ensure signal processing settings are configured to achieve optimal performance in terms of SNR and THD+N.
Grounding and Decoupling:
- Use proper grounding techniques and place decoupling capacitors close to the power supply pins to minimize noise and improve stability.
Digital Interface:
- Configure the I2C or SPI interface as needed for communication with the device.
Audio Path Setup:
- Set up the audio path configurations via registers using the digital interface to control various functionalities such as gain, mute, etc.

Note: Always refer to the official datasheet for detailed specifications and application notes.
