  • INA199: IC damage due to nanosecond over-voltage condition

    Resolved
    Part Number: INA199 I have redesigned my schematic to check the high side of the switch but I'm still seeing the output stuck at 0.03V. I'm looking at the inputs of the voltage pins and the voltage is rippling above 26V for ~20ns when the switches…

  • INA199: abnormal value( not linear with current sense)

    Part Number: INA199 Hi Experts, Customer application schematic is like this. The REF pin add a positive voltage 1.65V. The waveform is like this(Green waveform is the Current from SGND to LGND. Blue waveform is OUT pin voltage). The question is that…

  • RE: INA199: Bulk Current Injection Support

    Hi Prashaant, Prashaant Yerrapragada said: Also is there any standard recommended value for Rs and Cf values that we can go ahead and try. Section 8.4.1 of the datasheet recommends Rs < 10 Ω. You can determine Cf from the cutoff frequency equation:…

  • INA139: VS INA199

    TI Thinks Resolved
    Part Number: INA139 Other Parts Discussed in Thread: INA199 Hi, I'm choosing a current sense amp. INA139's GAIN can be set by external RL. INA199's GAIN is fixed with different version. When should I choose INA139 and when should I choose…

  • INA199: Unstable reading

    Part Number: INA199 Other Parts Discussed in Thread: OPA325 Hi Team, Can you please help check the circuit below? The circuit uses INA199A1DCKR to monitor the current charging for a battery. But the issue is that the raw ADC reading was very noisy and…
