  • THS3491: THS3491RGT

    Resolved
    Part Number: THS3491 I find myself looking at the .lib file for the THS3491RGT, right at the top looks to be the trace resistance for the internal feedback trace in the RGT package - the datasheet says 1.5ohm, but this says 1uOhm - should this be changed…

  • THS3491: Pspice for TI Simulation Issue

    Resolved
    Part Number: THS3491 Good morning! I'm simulating a simple transimpedance amplifier made with THS3491. When doing a transient analysis, I've got a modulated wave as a result. What could be wrong?

  • THS3491: THS3491+VCA824 circuit problem

    Resolved
    Part Number: THS3491 Other Parts Discussed in Thread: VCA824 Hi, I would like to ask you to give me your advice about THS3491-VCA824 circuit. The problem is the gain difference between design value and measured value. I designed the THS3491 gain as around…

  • THS3491: modeled noise in simulation is 3x higher than theoretical

    Part Number: THS3491 Other Parts Discussed in Thread: THS3001 , , TINA-TI Is the THS3491 simulation model supposed to be able to do a reasonable job of modelling noise ? I ask because I'm getting 300% higher noise predictions in simulation from the THS3491…

  • THS3491: Amplifier power down not always behaving

    Part Number: THS3491 Hi We are using the THS3491 (RGT) package in our design with bipolar +/-14V rails. We use a single power down signal for a bank of THS3491 amplifiers to power-down all of them at once, with the power down either at 5V or 0V. We have…

  • THS3491: Max Quiescent Current

    Resolved
    Part Number: THS3491 Hi, Let me ask you a question about "Max Iq" value as below. There described the value is 16.3mA (at Vs=+/-7V) on the datasheet page7. In case Vs=+/-10V, how much current can we estimate? And about the value, can I understand…
