  • INA146: INA146 High Voltage Isolation

    TI Thinks Resolved
    Part Number: INA146 I have an application where I need to measure differentially a voltage that is nominally between 5 and 25 volts. However, under overload conditions, the input can go as high as 72 volts. The INA146 looks like it can handle this with…

  • INA146: Non linear read in AC current reading (simulation)

    Part Number: INA146 I have a simple AC circuit with a 100 ohm load. I've two INA146 chips (a differential op-amp with offset and second op-amp for gain). The output will go into a MCU at 3v. I use two voltage offsets to keep the common mode above the…

  • INA146: Removing the offset from the amplification stage

    Part Number: INA146 Other Parts Discussed in Thread: TINA-TI Hi there, I've an AC current reader prototype using the INA146. I'm using a offset 2.5v reference and the max peak is around the 70v mark (~50v RMS). One aspect I need to verify…

  • INA146: ESD protection on INA146 inputs

    TI Thinks Resolved
    Part Number: INA146 Other Parts Discussed in Thread: TVS3300 , TVS2200 , INA148 , INA149 , INA132 Hi, Is there already a general or well-tried practice to protect INA146 against ESD event which meets the criteria of the IEC 61000-4-2 standard? I find…
