  INA240: Behavior of INA240 when IN+/- is floating

  TI Thinks Resolved

  Part Number: INA240 Hi team, customer has some question about INA240. they apply 3.3V to VS, and observe IN+/- are1.34V. and IN+/- is. actually, floating. Is this behavior is correct? and if so, could you tell me the error of this IN+/-...

  INA240: Differential input broke amplifier?

  Part Number: INA240 Hi, We are using the INA240 to detect if a charger is disconnected from the charger input, to avoid battery voltage present on the battery charger input. The battery voltage is 36V (3x12V Pb). Normally the transistor stage is closed...

  RE: INA240: Using INA240 (any instrumentation amplifier in general) In a Feedback Loop

  Rohat, Thanks for choosing E2E! I see a few things you need to think about here. As the attached app note explains, a challenge of stability here when using two amplifiers in a feedback loop is the further reduction of phase margin in the system....

  RE: Current sense circuit

  Ghiran, The issue here is that the low end of your current range is approaching where the bias currents and offset of a current sense amplifier begin to interfere with the accuracy of the measurement unless you use a rather large shunt. For example...
