Hi team,
One of my customer will use INA186 and he is asking a question about value of Rprotect.
At customer's application, there would be negative voltage at input and he would like to limit current within 5mA.
He considers to add 2kΩ as Rprotect in figure.33.
- Is it okay to use 2kΩ as long as they can accept error by Rprotect?
- Is there maximum limit for Rprotect except for because of error?
- Is there any other concern by adding current limit resistor?
Best regards,
Shota Mago
