  • INA250: The INA250 output is overshot and needs optimization

    TI Thinks Resolved
    Part Number: INA250 Other Parts Discussed in Thread: INA253 Tool/software: ATE guessing application, Test condition: ref=2.5V Power Rail input voltage step is 0.1 0.2 0.3 0.4 0.5V, etc INA250 output overshoot; Is there any optimization method? Reduce…

  • RE: INA250: current flow and output mismatch

    Hey Showrya, I'm just following up on this thread. Were you able to fix this problem? If not, can you please share a schematic so that we can investigate further? If you don't reply, I'll presume that your issue has been solved. Regards, …

  • INA250: Instability with OPA549 with INA250 in feedback loop

    Part Number: INA250 Other Parts Discussed in Thread: OPA549 Hi there, I am trying to create a bipolar transconductance amplifier using the OPA549 as the current driver and the INA250 as shown in the circuit diagram below. The output of the OPA549 goes…

  • INA250: Voltage is dropped at different points on a PCB

    TI Thinks Resolved
    Part Number: INA250 Other Parts Discussed in Thread: INA186 Hello! I have a PCB with an INA250A4. I connected a 5 Ohms potentiometer in High-side configuration that supports up to 4.47 amps, the output voltage of the integrated does not correspond to…

  • INA250: Simulating in LTSpice

    Part Number: INA250 Other Parts Discussed in Thread: TINA-TI Hi, I'm having trouble implementing the PSpice or TINA-TI models in LTSpice and I was wondering if anyone else has had any success. The errors I am getting imply that the model is broken…

  • INA250: Measuring mains current

    TI Thinks Resolved
    Part Number: INA250 Other Parts Discussed in Thread: INA302 , TMCS1101 , AMC1300 Hi, Any advice against using a INA250 to measure mains AC line current, using an isolated power supply? Input current range is from 1mA to 10A. Being AC only, offset figures…

  • INA250: INA250A1PWR current sense readings not as expected

    TI Thinks Resolved
    Part Number: INA250 Hi TI forums! We've come across a hiccup while testing some of our newly designed boards. Initially we thought it was a FW error when our current readings were not exactly as expected. However on one of our designs we have two of…

  • RE: INA250-Q1: INA250A2 power source to +IN & VS pin can be same or not?

    Resolved
    Hello All, Sorry for the late reply but I was out of the office. Latha, Since the INA250 is very precise I would go with a precision op Amp with a rail to rail input and output as Kai mentioned. You can use the parametric search on the TI website to narrow…

  • INA250: Is this implementation correct?

    Resolved
    Part Number: INA250 Issue I am currently consistently getting 235% of the output voltage compared with what is expected using an INA250A4 and an INA250A2. For example, using the INA250A4, with a current of 0.5A, the output is 2.35V which correlates to…
