Part Number: INA181 Do the sense inputs need to have a ground reference connected to the ground of the supply voltage? Or is it completely differential?
Part Number: INA181 Tool/software: Hello TI team,
I am planning to use the Current sensing Opamp INA181A1 and INA181A2 with one of my recent project. I had a query if I will use this to sense a current which is specified as below:
1. Max DC current…
Part Number: INA181 I am trying to simulate a circuit with an INA181 current sense IC.
I have boiled it down to this circuit:
And I just pulled the spice model today.
When Vs1 is 0V (i.e., shorted to ground) I get this:
Note the time delay…
Part Number: INA181 Tool/software: Hi Team
As I describe on the title, customer needs their current sensing circuit gain as: 100V/V>Gain> 75V/V, so they wanna change the Rf resistor to get their requirement.
They changed the Rf resistor to change…
Part Number: INA181 Hello.
When I was using the current detection chip INA181A2IDBVT, the reference pin of the fifth pin increased the reference voltage by 0.1-0.2V, causing the reference voltage I reported to change from 1.6V to 1.8V. So I don't understand…
Part Number: INA181 Tool/software: We have a INA181 mounted like so where +Vout and ++Vout are seperated by shunt resistors. The INA circuit measure the current just fine. The Iout signal is fed into a MCU. In my MCU I have a PID that will regulate the…
Part Number: INA181-Q1 Other Parts Discussed in Thread: INA181 Hi @TI team;
Due to transint coming on across shunt resistor during relay contactor closing time.INA181 IC geeting burnt. Data sheet specifies common mode negatiove voltage of -0.2V but…
Part Number: INA181 Tool/software: Hello TI Team :-)
The basic definition of input common mode is the average voltage of IN+ and IN-.
Does this always hold true? Especially when reading the Abs Max table?
For example:
IN+ = 0.0V
IN- = -0.4V…
