  • RE: OPA462: Input Bias and Powerpad query

    Hi Robert, Thank you for getting back to us regarding your findings about the OPA462 circuit. I'm glad you were able to determine that the lack of a dc path for the input is the cause of the problem. If you require any additional assistance going forward…

  • RE: OPA462: Supply voltage drop

    Resolved
    Small update: Having a voltage divider for the E/D and E/D com input seems to have fixed the issue. Thank you for your help

  • OPA462: OPA462IDDAR, start-up voltages

    TI Thinks Resolved
    Part Number: OPA462 Hello We provide a differential voltage power supply, powering the OPA462 I noticed, on start-up, the negative voltage V- arrives before the positive V+. On the positive power supply we have a little undershoot of -1.4V, while the…

  • RE: OPA462: OPA462 3 Op Amp Configuration - Is Heat An Issue At 'Low' Load and or 'Low Voltage'?

    Hi John, Here is an example of current booster design concept that may meet your design requirements. I did not place current limiting and rest of protection circuitry in the simulation. Since OPA462 has the current protection feature, you may design around…

    Part Number: OPA462 Hello, Are the design files available for what was demonstrated in SBOA510 ? Thanks, John W.

  • OPA462: Supply voltage 200V solution

    TI Thinks Resolved
    Part Number: OPA462 Our customers used LME49810 originally, and the withstand voltage can be up to 200V. Now the product is upgraded and transformed. It is found that LME49810 is not recommended. Which model uses 200V power supply? I found that OPA has…

  • OPA462: Application for HV capacitance measurement

    Resolved
    Part Number: OPA462 Hi team My customer is looking for op-amps for their design in measuring capacitance of their HV circuit(hundreds volt). He found OPA462 to be the op-amp with the highest maximum voltage, and is wondering if it could be used as charge…

  • OPA462: OPA462 Heating

    Resolved
    Part Number: OPA462 Hi Team, A customer supplies 170-180V to OPA462 and the device turns hot. Whenever he reduced the supply voltage the device cools down. Upon checking the quiescent current of the device, it consumes 2mA which translate to 180V x 2mA…
