Instrumentation Amplifier Vin Vout Question

[Kv3t4k]

Hello,
Sorry for my bad English, but i have never learned English.I have a question about the Instrumentation Amplifier.
I am using INA828 for the current sense through the voltage drop on the resistor. I will be measure current flow in to the DC-DC convertor.
I need measure current only when DC-DC convertor is running without load, so the current flowing into him shoud be between 10-14 mA.
Circuit connection is shown in the attachment.
Input voltage is 5V DC
Resistor is 0,27R
Gain is set to 501
Vs+ =s +10V
Vs- = -10V
By my calculations for the output voltage shoud be 1,353V(10mA) - 1,894V(14mA) depends on the current.
So my question is when i turn on the load of the DC-DC convertor, there shoud be current flowing through the resistor about 140mA. Can it cause some damage to the INA828, because voltage drop on the resistor will be 0,0378V and output voltage would try to achieve 18,938V but it is impossible with supply voltage i have using.
Thank you very much.

What you describe is called op-amp (in this case in-amp) saturation. When power rail voltage is not enough to achieve required output. No damage will occur from that. The only negative aspect is that most op-amps spend some time to get out of saturation. So if you overdrive it and then the signal drops, it reacts slower then overwise slew rate would alow, with a delay. I think it really does not matter in this application.

The general rule is to keep inputs between the power rails. Functional range could be smaller if inputs are not "rail to rail". In your case, none of inputs should go below -10V or above +10V, then everything will be fine. There are op-amps and in-amps which have some protection or extended range and can tolerate more voltage without damage. INA828 datasheet states +-40V.

I was not 100% sure, but i think it shoud not be a problem. Thank you very much for quick response.
