Instructions for AD7616BSTZ:

1. Powering the Device:

   • Connect AVDD and DVDD to appropriate power supplies within the specified voltage ranges.
   • Ensure proper bypass capacitors are placed close to the power pins.

2. Analog Input Configuration:

   • Connect analog signals to the differential input channels.
   • Ensure input voltages do not exceed the specified full-scale range.

3. Digital Interface:

   • Use SPI interface for communication.
   • Configure the digital control lines (CS, SCLK, DIN, DOUT) as per the datasheet timing diagrams.

4. Initialization:

   • After powering up, send initialization commands via the SPI interface.
   • Set the desired configuration such as channel selection, data format, etc.

5. Data Acquisition:

   • Initiate a conversion by sending the appropriate command over SPI.
   • Read the conversion results from the ADC.

6. Power Management:

   • To reduce power consumption, use the device's power-down modes when conversions are not required.
   • Return to active mode before initiating new conversions.

7. Calibration:

   • Perform system calibration if necessary to ensure accurate measurements.
   • Follow the recommended calibration procedures outlined in the datasheet.

8. Handling and Storage:

   • Store the device in anti-static packaging when not in use.
   • Handle with care to avoid damage to the sensitive components.
