Power Supply Configuration: Ensure the supply voltage is within the specified range (2.7 V to 5.25 V). Connect the appropriate power supply to the VDD and GND pins.
Analog Input Connection: Connect the analog signal to be measured to the input pins. Make sure the input signal does not exceed the input range to avoid damage or incorrect readings.
Digital Interface Setup: Configure the SPI interface by connecting the MOSI, MISO, SCLK, and CS pins to your microcontroller or processor. Refer to the specific SPI protocol details in the datasheet for timing requirements.
Initialization: Before starting conversions, initialize the ADC according to the datasheet specifications. This typically involves sending configuration commands via the SPI interface.
Performing Conversions: Start a conversion by setting the appropriate command via the SPI interface. The ADC will perform the conversion and return the result through the same interface.
Reading Results: After the conversion time has elapsed, read the result from the ADC using the SPI interface. Ensure that the clock frequency used does not exceed the maximum allowed for accurate data transfer.
Power Management: For low-power applications, consider using the power-down mode if available. This can significantly reduce power consumption when the ADC is not actively converting.
Calibration: Periodically calibrate the ADC to maintain accuracy, especially in environments where temperature changes are significant. Calibration procedures are detailed in the datasheet.
