  • RE: THS3491RGTEVM: 15V square wave from 3V3

    Hi Ahbib, please show your latest schematic. And please post a photo which shows your modifications carried out on the EVM board. Maybe you have damaged the OPAmp during experimenting? Then check again with a fresh one :-) Kai

  • THS3491RGTEVM: Adding offset voltage to the amplified signal

    TI Thinks Resolved
    Part Number: THS3491RGTEVM Other Parts Discussed in Thread: THS3217 , THS3491 Hell there, I have a THS3491RGTEVM and want to use it to amplify 20-40M square wave to 10Vpp (with input up to 1Vpp). I can get the waveform amplified to 10Vpp with a gain of…

  • RE: THS3491: Zol test and parasitic capacitance of noninverting terminal questions

    Resolved
    Hi Kai, As you said, I built the same circuit with THS3491RGTEVM and the thin board. The Rf of both of them are 300Ω. While EVM is stable and thin board is not. So I think there is two possible scenarios to explain why the thin board is instable.…

    Resolved
    Hi Stefan, have you read section 2.2 of the EVM manual? www.ti.com/.../ths3491rgtevm Maybe the resistors of the output resistor network have some manufacturing tolerances? For a small signal response measurement you could replace the output resistor…
