  • OPA547: How much ESD current can pass into the output of this amplifier?

    Part Number: OPA547 Other Parts Discussed in Thread: OPA549 I have a design using the OPA547 that has a 10 ohm resistor in series with the output. This just to aid in stability. Anyway, the resistor is between the output of the amplifier and the external…

  • OPA547: Thermal resistance clarification

    Part Number: OPA547 Hello Guys, Good day. I see a theta JC on the data sheet and a theta JA. I would like to know what the case resistance represents. Is it the thermal resistance from the junction to the ground slug? Do you have a value for that thermal…

  • OPA547: OPA547: ILIMIT NOISE ISSUE DURING THE POSTIVE VOLTAGE CYCLE

    TI Thinks Resolved
    Part Number: OPA547 Other Parts Discussed in Thread: OPA170 Hi, We are using OPA547 in one of our programable power supply design where the voltage can be varied from -5V to 5V & Ilimit current is set to 200mA. In this section when ever the voltage is…

  • OPA547: OPA547 OP-AMP current limit (Ilim) resistor calculation

    Part Number: OPA547 Other Parts Discussed in Thread: TINA-TI Hi, I am using OPA547 OP-AMP for our new project and I am using the below approach for limiting the current: I am using a 100K digital potentiometer instead of a variable resistor to control…
