Part Number: INA280 Other Parts Discussed in Thread: INA281 Hi,
INA280 works fine with common mode voltage of 2.7V till 110V. Is the INA280 also suitable to detect a hard short cut to GND, which pulls also the input pin down to GND?
How long long is the…

Hi Team,
Good day. We need your help to check the PDF files on the TI Precision Labs - Current Sense Amplifiers: Input Filter Error .
Two concerns were notice by our customer as stated below.

Part Number: INA280 Hello Team,
can you share for the INA280A1DCKR the following qualification data
- FIT rate - usage temperature - confidence level - activation energy
Thanks,

Part Number: INA280 Hi team,
Can the INA280 measure the overall load current on the same voltage source (3.3V) that powers it? This would effectively mean that Vs=V+=3.3V, and V- is somewhere in the vicinity of 50-200mV less (say 2.8V min., 3A through…
Part Number: INA280 Other Parts Discussed in Thread: INA290 , TINA-TI , INA195 Is there already a pspice model for INA280 or a model that behaves similar.
Hello Jacky,
As you increase the Rg the bandwidth of this device goes down. This device is limited by the bandwidth. If you need faster response please use the INA296A or INA296B, INA293 or INA290, INA281 or INA280. I know they do not have the selectable…
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…
Hey Harry,
The only way to improve this for INA214 is to provide a small reference voltage to REF pin (> 50mV). This will ensure OUT is always in linear region.
The other option is to simply use a faster device such as INA181, INA280, or INA281. The…
Part Number: LM25148 Other Parts Discussed in Thread: INA280 I am developing a power converter based on the LM25148. My first design was not stable and I could not diagnose the problem so I backed up to the typical design #2 in the datasheet. I recreated…
Hello Mohammed,
Generally your schematic looks good to me, however, I would recommend removing capacitors C1 and C2, as they can cause error when mismatched. Here is an e2e thread that discusses more about this: https://e2e.ti.com/support/amplifiers-group…
