  • OPA192: clarification on operation below max current limit to input pins

    Resolved
    Part Number: OPA192 we are currently using a zener diode in our circuit for input pin protection where leakage current in some parts have become a concern. we would like to remove it altogether if possible given the large resistance already in series…

  • RE: OPA192: Transimpedance amplifier issue

    In case of OPA192 using a dual +/-5V supplies (with VTIA nulled to zero), you would simply connect VTIA to the input of second stage as shown below. The ADC input would then be reference to GND. In case of OPA392 using a single 5V supply, you would …

  • OPA192: Map to model in Autodesk Eagle for OPA192

    TI Thinks Resolved
    Part Number: OPA192 Hi all, I am now trying to simulate the OPA192. And I build the circuit using Eagle S/W (Our in-campus pcb circuit fabrication tool only accepts Eagle. So it's unchangeable) and I am having trouble in mapping the OPA192 component…

  • OPA192: No Connect (NC) pins

    Resolved
    Part Number: OPA192 In aerospace, there is a no floating metal requirement, ex: unused pins are tied to ground through some resistor. What is TI recommendation on NC pins for the OPA192IDR? Leave floating or tie to GND through some resistor?

  • OPA192: Question about the offset voltage

    Resolved
    Part Number: OPA192 Hi, Let me know the following, I think that the offset voltage specs over 0℃to85℃ and -40℃to125℃ in the OPA192 D/S include the effect of Input offset voltage drift. but when I calculate the max offset voltage @ +125℃ from the max…
