Instructions for Using AD7247JN:

1. Power Supply Connection:

   • Connect the supply voltage (VDD) within the range of 2.7V to 5.5V.
   • Ensure a stable power supply to avoid noise and instability.

2. Analog Input Configuration:

   • The analog input voltage (VIN) should be referenced to AGND.
   • Ensure that the input signal does not exceed the supply voltage (VDD).

3. Output Data Rate Setting:

   • Set the output data rate (fODR) up to 100 kSPS as required by your application.
   • Higher data rates may increase power consumption.

4. Resolution Consideration:

   • The AD7247JN provides a resolution of 12 bits.
   • Use this resolution to determine the precision of your measurements.

5. Linearity Calibration:

   • Check and calibrate for Integral Nonlinearity (INL) and Differential Nonlinearity (DNL) errors to ensure accurate readings.
   • Typical values are within ±4 LSB for INL and ±1 LSB for DNL.

6. Error Correction:

   • Account for offset and gain errors, especially when high accuracy is required.
   • Offset error is typically within ±4 LSB and gain error within ±1% FSR.

7. Power Management:

   • Utilize sleep mode to reduce power consumption when the ADC is not actively converting.
   • Transitioning to sleep mode can significantly lower power to approximately 0.5 μA.

8. Signal Integrity:

   • Ensure proper layout and decoupling capacitors to maintain signal integrity and minimize noise.
