  • OPA462: while the device is disabled

    Resolved
    Part Number: OPA462 Hi team, According to the datasheet, it seems that the output impedance just increases to about 160kOhm while the device is disabled. But are there any changes else while the device is disabled? Regards, Noriyuki Takahashi

  • 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…
