Instructions for AD790JRZ

1. Power Supply Connection:

   • Connect the supply voltage (VDD) between 4.75V and 5.25V to the VDD pin.
   • Ensure a stable power supply to avoid noise and instability in the output.

2. Reference Voltage Setup:

   • The internal reference voltage is approximately 2.5V, which can be used directly for most applications.
   • For external reference, ensure the voltage does not exceed the specified range.

3. Analog Input Configuration:

   • Apply the analog input signal within the range of 0V to VREF.
   • Avoid exceeding the input range to prevent damage or inaccurate readings.

4. Output Current Measurement:

   • The device provides an output current proportional to the input voltage.
   • Calibrate the system to interpret the current as a corresponding voltage or digital value.

5. Calibration and Accuracy:

   • Perform initial calibration to account for linearity errors.
   • Regularly check the temperature coefficient to maintain accuracy over varying temperatures.

6. Thermal Management:

   • Operate within the industrial temperature range (-40°C to +85°C).
   • Ensure adequate heat dissipation if operating near maximum power dissipation levels.

7. Handling Precautions:

   • Handle with care to avoid static discharge, which can damage sensitive components.
   • Follow standard ESD precautions during installation and maintenance.
