Instructions for Use

1. Supply Voltage:

   • Ensure the supply voltage (VDD) is within the range of 2.7V to 5.25V.
   • Connect the positive supply to VDD and the negative supply to GND.

2. Input Connections:

   • Connect the differential input signals to the IN+ and IN- pins.
   • Ensure the input voltage range does not exceed -0.3V to VDD + 0.3V to avoid damage.

3. Output Connections:

   • The output voltage (VOUT) will be between 0.01V and VDD - 0.01V.
   • Connect the output to the load or next stage of the circuit.

4. Bias and Offset Considerations:

   • The input bias current is typically 50nA, which can affect high-impedance sources.
   • The input offset voltage is ±20μV, which may need to be compensated for precision applications.

5. Common Mode and Power Supply Rejection:

   • The AD7247JR has a CMRR of 90dB at 60Hz and a PSRR of 80dB at 60Hz, making it suitable for applications where these parameters are critical.

6. Bandwidth and Slew Rate:

   • The bandwidth is 1.2MHz at -3dB for a gain of 1, and the slew rate is 0.5V/μs, which should be considered for high-frequency applications.

7. Power Consumption:

   • The quiescent current is 200μA at 5V, which is relatively low and suitable for battery-powered devices.

8. Short Circuit Protection:

   • The output can handle up to 20mA of short-circuit current without damage.

9. Handling and Storage:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Store the device in a dry, cool place to prevent moisture damage.
