  • INA280: INA280 - output filter

    Resolved
    Part Number: INA280 Hello Team, due to cable length between the end device and the output of the INA280, we are considering adding a filter on the output. In particular as shown in the picture the first RC is 100R 100pf, the other RC 1K 10n. this opens…

  • INA280: short cut detection and overload recovery time

    TI Thinks Resolved
    Part Number: INA280 Other Parts Discussed in Thread: INA281 Hi, INA280 works fine with common mode voltage of 2.7V till 110V. Is the INA280 also suitable to detect a hard short cut to GND, which pulls also the input pin down to GND? How long long is the…

  • INA280: Can Part Measure the Total Current Supplied by its Own Vs?

    TI Thinks Resolved
    Part Number: INA280 Hi team, Can the INA280 measure the overall load current on the same voltage source (3.3V) that powers it? This would effectively mean that Vs=V+=3.3V, and V- is somewhere in the vicinity of 50-200mV less (say 2.8V min., 3A through…
