Instructions for Use:

1. Power Supply:

   • Connect the VDD pin to a stable power supply within the specified range (2.7V to 5.25V).
   • Connect the GND pin to the system ground.

2. Analog Inputs:

   • Connect the analog signals to the differential input pairs (AIN0 to AIN7).
   • Ensure the input voltages do not exceed the specified range (0V to VREF).

3. Reference Voltage:

   • Connect the reference voltage (VREF) to a stable reference source.
   • The reference voltage should be within the range of 2.5V to 5V.

4. Digital Interface:

   • Connect the SPI interface pins (SDI, SDO, SCLK) to the corresponding pins on your microcontroller or digital system.
   • Configure the SPI settings according to the datasheet specifications.

5. Grounding:

   • Ensure proper grounding to minimize noise and interference.
   • Use a star grounding technique if multiple grounds are involved.

6. Decoupling Capacitors:

   • Place decoupling capacitors (0.1 μF and 10 μF) close to the VDD and GND pins to filter out high-frequency noise.

7. Configuration:

   • Use the configuration registers to set up the ADC according to your application requirements (e.g., channel selection, conversion mode).

8. Data Acquisition:

   • Initiate conversions by writing to the control register.
   • Read the converted data from the output register using the SPI interface.

9. Handling:

   • Handle the device with care to avoid static discharge.
   • Follow ESD (Electrostatic Discharge) precautions during handling and installation.

10. Storage:

    • Store the device in a dry, cool place away from direct sunlight and moisture.
