Team, can you please help with the questions below.
I am monitoring a input voltage supply point that can vary from 4V to 35V. I am dividing the voltage by a factor of 200/1440, so that at 36V, the input to the op amp IN+ pin is 5V. I am using the op-amp as a unity gain buffer feeding the input to an A/D. Is this device OK to use in this application, or should I use something else? The input voltage is DC, and I have a capacitor to create an anti-Aliasing filter at about 300Hz.
I have two questions:
1. Can the MP7701MF handle 5V on the Vin pin with the device being un-powered?
2. I see that Vin has a max differential voltage of +/- 300 mV, but the input pins are rated to Vdd +0.3V. What does this spec mean? Does this result in question #1 being a no?
Thanks
Viktorija
