  • OPA1692: output amplitude with different load

    Resolved
    Part Number: OPA1692 Hello， According to the Figure 13. Maximum Output Voltage vs Frequency of OPA 1692, we could get to the conclusion about the output amplitude is more than 4Vp when the Frequency less than 1Mhz with +-5V,2Kohm load. So if the power…

  • OPA1692: OPA1692 Gain issue with high feedback resistor

    Resolved
    Part Number: OPA1692 Hi, I've got 4 pieces of OPA1692. After simulating the circuit on TINA, I implemented the physical circuit. The problem is the gain: Theoretically and on TINA the result was the same G=49.24dB, but in the practical circuit the result…

  • OPA1692: ESD problems

    TI Thinks Resolved
    Part Number: OPA1692 Dear all, I want to use the OPA1692 for three new products, because they fit theoretically perfect in our applictaion. But we made ESD tests according to EN 61000-4-2. All products have TVS protection diodes at the in- and outputs…

  • RE: OPA1692: Problem implementing OPA1692 LT Spice and on Breadboard

    Resolved
    Hi Alex, I think the OPAmp based voltage regulator does not work properly, because it sees a too high source impedance. I don't think that it has to do with the OPA1692 itself. That's why I asked you to test the circuit with a 15V standard regulator…
