  • INA111: INA111 Offset

    Resolved
    Part Number: INA111 Hallo, i want to juse the INA111 with Gain of 1, 10, 100 and 1000. The Datasheet says that the Offset RTI is 100uV + 500uV/G. I mean with Gain z.b. 1000 the Offest may be 100 + 500/1000 similar 100.5 uV. In my case I measure with…

  • INA111: Output Current Protection

    TI Thinks Resolved
    Part Number: INA111 Hello, I am working with an INA111 powered with a symmetrical source of +-5V, and the output needs to be single supply (5V). I added an Schottky diode (parallel to the output) to prevent this voltage to be negative. I want to know…

  • INA111: Trouble getting gain for output signals.

    Part Number: INA111 Hello, I have a INA111BP I am using in a research setting to amplify a signal/reduce noise coming from a non-contact displacement measuring capacitive probe. The probe runs from a coaxial connection to a Capacitec 210-SLC-200Hz pre…
