Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.7V to 5.5V.
   • Connect a bypass capacitor (typically 0.1μF) close to the V_CC pin to filter out noise.

2. Reference Voltage:

   • The internal reference voltage (V_REF) is 2.048V. If an external reference is used, ensure it is stable and within the specified range.

3. Sampling:

   • Set the sampling frequency (f_S) between 200kSPS and 1000kSPS using the appropriate clock input.

4. Analog Input:

   • Connect the analog signal to the analog input pins. Ensure the input signal does not exceed the supply voltage range.

5. Digital Interface:

   • Use the SPI or other supported digital interfaces to read the ADC conversion results.
   • Refer to the datasheet for specific timing diagrams and command sequences.

6. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C to ensure reliable performance.

7. Layout and Grounding:

   • Follow good PCB layout practices, including proper grounding and signal routing, to minimize noise and interference.

8. Testing and Calibration:

   • Perform initial testing and calibration as per the datasheet recommendations to ensure optimal performance.
