  • INA212: INA212 application check

    TI Thinks Resolved
    Part Number: INA212 Tool/software: Hi Expert, My customer have one new design and use INA212. The ina212 is used to detect if its Relay has a voltage output. (L is AC supply 100 - 240V) Relay is not controlled, INA212 has output voltage of out1(NO) output…

  • INA212: offset voltage spec referred-to-input

    Resolved
    Part Number: INA212 Hi team, About our INA212 offset voltage spec as following: What does the 'RTI' mean? Does this mean the offset error should be calcualted into input side; and the output side offset error will be the Vos*Gain like normal amps?…

  • INA212: Minimum measurable current

    Resolved
    Part Number: INA212 Other Parts Discussed in Thread: INA211 , INA190 , INA186 Hi Team, We are using INA211 / INA212 current sense amplifier to measure current in our design. When we tried doing simulation we were not getting expected output when the current…

  • 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: 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…
