Other Parts Discussed in Thread: INA118, TINA-TI

Hello,

I'd like to do a DC amplification thanks to INA118, from (O/1 V to 0/10 V )  is it possible or it's just an AC amplifier  ?? 

because i didn't achieve to do it

Thank you !

    Hello Thib,

    The INA118 can do DC amplification.  Could you give me more information on what you are seeing (voltage magnitudes).  Scope shots of the output, Input signal (DC voltage), Schematic, and what is driving the input of the INA (ex. sensor).

    Best,

    Thib,

    You have not provided power supply used in your application.  The simplest way to accomplish a gain of 10 would be to use +/-15V supplies as shown below:

    I have attached below Tina-TI schematic you may use for your own simulations:
