  • OPA991: High-side current monitor unstable, but TL071 works, as does INA168

    TI Thinks Resolved
    Part Number: OPA991 Other Parts Discussed in Thread: LM321 , TL071 , , INA168 , TLV9351 Tool/software: Hello, We want to put out a 4-20mA current (process control) from a filtered PWM. Since we set it from a micro, it is low-sede, but we need a high…

  • INA168-Q1: Question for Bipolar current measurement.

    TI Thinks Resolved
    Part Number: INA168-Q1 Other Parts Discussed in Thread: INA168 , INA240 Tool/software: When FOLD operating, I checked voltage between OS MRR shunt In and OS MRR shunt Out is 73 mV. And Shunt Forward voltage 395 mV So we can calculated 732 mA. And…

  • INA168: Temperature Operation

    Resolved
    Part Number: INA168 Good morning, I have been looking at the datasheet for INA168NA and I don't know why the operation temperature is only defined for the P/N of the 3K reel (P/N INA168NA/3K) but not for the 250 un reel (P/N INA168NA/250) I suppose…
