Instructions for Use

1. Power Supply:

   • Connect the VDD pin to the supply voltage within the range of 2.7 V to 5.25 V.
   • Connect the VSS pin to ground.

2. Digital Interface:

   • Connect the SPI interface pins (SCK, MOSI, MISO, CS) to the corresponding pins on your microcontroller or processor.
   • Ensure that the SPI clock (SCK) is within the specified frequency range for proper operation.

3. Configuration:

   • Use the configuration registers to set up the desired operating mode, such as the input channel selection, conversion rate, and other parameters.
   • Refer to the device datasheet for detailed register maps and configuration settings.

4. Data Conversion:

   • Initiate a conversion by writing to the appropriate control register.
   • Read the conversion results from the data registers using the SPI interface.

5. Calibration:

   • Perform system calibration if required to ensure accurate measurements.
   • Calibration can be done using the internal self-calibration feature or external calibration methods.

6. Handling and Storage:

   • Store the device in a dry, cool place to avoid moisture damage.
   • Handle the device with care to prevent electrostatic discharge (ESD) damage.

For more detailed information, refer to the CS5534-ASZ datasheet provided by the manufacturer.
