Frequent questions

  • [FAQ] INA199: Does power sequencing for my current shunt monitor matter?

    Part Number: INA199 I expect that when I turn on my system, there will be a delay between when my microcontroller is ready for measurement and when my INA199 is properly powered on. Will this produce errors in my microcontroller readings?

  • [FAQ] INA199: Dealing with device protection when you can't exceed -0.3V

    Part Number: INA199 How do I protect against reverse current when I can only allow my signal to be 0.3V below ground?

  • [FAQ] INA199: Closed Loop Output Impedance and Output Compensation for Capacitive Load Stability

    Part Number: INA199 Other Parts Discussed in Thread: TINA-TI , How do I use the closed loop output impedance (Zout) to stabilize the output of a current sense amplifier with a capacitive load?

  • [FAQ] INA226: Choosing a Pull-up Resistor for an I2C Bus

    Part Number: INA226 How do I choose a good pull-up resistor to use on an I2C bus?

  • [FAQ] INA210: What effect do external resistors on VREF have on CMRR/Gain error?

    Part Number: INA210 I want a simple, cheap solution to provide a reference to the VREF pin of my device. Are there any issues with using a voltage divider to set VREF?

  • [FAQ] Where do I connect the power pad for an operational amplifier?

    Some devices have a power pad on their package, where should you connect it?

  • [FAQ] In a multiple amplifier package, what do I do with any unused amplifiers?

    If your design uses a multiple amplifier package like a dual or quad, you may find that some amplifiers are unused. What is the best way to configure the unused amplifiers?

  • [FAQ] Where can I learn about current sensing techniques, product selection and achievable accuracy?

    I would like to measure current but I don't know where to start - how do I choose the right current sense amplifier or current shunt monitor with integrated data converter? What kind of accuracy can I achieve? Please help me to understand!

  • [FAQ] What are some resources for understanding current sense amplifiers and current shunt monitors?
