  • INA212: High Current Consumption through IN+ / IN- Pins

    TI Thinks Resolved
    Part Number: INA212 Other Parts Discussed in Thread: INA214 , INA240 Related to my former post here: https://e2e.ti.com/support/amplifiers/f/14/t/930415 The INA212 in our system is drawing 5mW - 6mW. I have confirmed this is not being drawn through VDD…

  • INA212: Power Consumption with no V+ Applied

    TI Thinks Resolved
    Part Number: INA212 Hi, We have designed in the INA212 into our system, and are noticing the devices are drawing power when we have V+ grounded. Essentially we are powering the device V+ through a 3.3V GPIO, so are able to ground V+ when needed. REF…

  • RE: INA212: Input bias current of the INA212

    Hello, Regarding your question about no common mode you added a common mode voltage is that the input voltage is not controlled by any voltage. This means it is not bias and can move away from the INA212 ground potential. On your second circuit you limited…

  • INA212: Dual power supply capabilities

    Resolved
    Part Number: INA212 I want to use the INA212 to sense current over a resistor. However, I would like to power it with +5V and -5V, and not +5V and GND. The reason for this is that I would also be able to sense AC current through the resistor. I have simulate…

  • INA212-Q1: how to protect MCU pin connected with OUT pin

    Resolved
    Part Number: INA212-Q1 Other Parts Discussed in Thread: INA212 Dear all, We concern the situation when IN- pin and OUT pin is shorted. We connect IN- pin to 12V and OUT pin to 5V MCU. So, if they are shorted, MCU I/O pin will be broken by 12V. Could you…
