Part Number: INA4290 Hi Experts,
Seeking your assistance on this query from Cx.
They are looking for a current sense multiple channel that supports digital interface, but I am only seeing multiple channels of this type in analog output (i.e. INA4290). …
Part Number: INA4290 Hi sir,
I wanna confirm the chip status when the chip is at the following condition.
VS is stable at 15V.
Assuming that the (VIN +) - (VIN -) Voltage difference is stable at 0.1V,
what kind of process will output be in the process…
The absolute maximum ratings do not help you; to ensure that the device works correctly, you need to stay inside the recommended operating conditions.
The INA4290 supports up to 120 V with four channels. If that is too expensive, the next best choice…
Hey JH,
I think most of the current is flowing through IN+ because there is a path to ground as shown below in blue:
However, it really does not matter because the only way to decrease current is to increase RF for both input pins IN+ and IN-. However…
Hi Pedro,
As you mentioned, 3-decade is a big range to cover with accuracy. It might be possible with a simple solution as proposed. The concern however is if the accuracy requirement can be satisfied at 1mA.
INA4290 is a great choice, but I encourage…
