Hi all,
I have a prototype circuit board to test AD8212 for 100V application. Circuit is shown below.
I apply Input DC voltage and draw DC current. When i changed the input DC voltage step by step, while drawing same DC current at output, I cannot obtain same sensor output voltage. Result table is shown below.
Why the output voltage changes so much with my input voltage change? How can i solve?
| Input Voltage (V) | Output Current (A) | Output Voltage(V) (At Vout Node) |
|---|---|---|
| 30 | 0.985 | 0.466 |
| 70 | 0.985 | 0.308 |
| 80 | 0.985 | 0.268 |
| 90 | 0.985 | 0.227 |
| 95 | 0.985 | 0.179 |
