Instructions for Use:

1. Power Supply:

   • Connect the supply voltage (VDD) to a stable power source within the range of 2.7V to 5.25V.
   • Ensure that the ground (GND) is properly connected.

2. Input Signal:

   • Apply the input signal (VIN) within the range of 0V to VDD.
   • Avoid exceeding the input voltage range to prevent damage to the device.

3. Conversion Rate:

   • The typical conversion rate is 200 kSPS. Adjust the conversion rate according to the application requirements.

4. Output Data Rate:

   • Set the output data rate (ODR) between 0 and 2000 SPS as needed for your application.
   • Higher data rates may require more power consumption.

5. Linearity:

   • The device has a differential nonlinearity (DNL) and integral nonlinearity (INL) of ±1 LSB, ensuring high accuracy in measurements.

6. Error Correction:

   • Monitor and correct for offset error (VOS) and gain error (GAIN) as necessary to maintain precision in your measurements.

7. Power Consumption:

   • The typical power consumption is 1.5 mA. Ensure that the power supply can handle this current draw.

8. Resolution:

   • The device provides a 12-bit resolution, suitable for high-precision applications.

9. Operating Temperature:

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

10. Handling:

    • Handle the device with care to avoid static discharge and physical damage.
    • Follow proper ESD (Electrostatic Discharge) precautions when handling the device.
