Part Number: INA281 Other Parts Discussed in Thread: INA240 Hello, I am working on a board that utilize high side current sensing to record motor current. I have been observing some significant delay between my MOSFETs turning on and the current sense…
Hello Kura,
Below is my reply.
There is no issues with that circuit. See figure 5 in the datasheet to get the "Input Bias Current vs Common-Mode Voltage" when you have no current through the Rshunt what currents will run through the inputs.…
Part Number: INA281 Hello,
I am using the INA281 to read a current from an external PS that passes through this circuit. The loop for this current terminates in a different ground point than the ground used for the INA281. Does the current loop ground…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA281 Hi team,
My customer evaluated INA281A2QDBVRQ1 in their project, and met some issues now. Could you please kindly help to give some suggestions?
Refer the datasheet, INA281A2QDBVRQ1 can normally…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA281 , IWR6843 Hi Team
My customer said" I downloaded the case program about detecting the number of people and whether people fall, and found that there is a high delay in running the source…
Hi Wlliam,
the reason for the error is that you violate the common mode input voltage range of INA821. You must stay at least 2V away from the supply rails at the input:
One remedy is to increase V1 from +4V to +5V. Then you wouldn't violate the common…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA281 Dear Sir,
I have a confusion on the INA281 orderable partnumber.
What is the difference between INA281A4QDBVRQ1 and INA281B4QDBVRQ1?
Thanks,
Billy Xu
Part Number: INA281 Other Parts Discussed in Thread: INA240 Hi,
I'm redesigning an old project where there is a DC Motor (200W) and H-bridge composed by 4 mosfet IRFS3206 ( ID max ~120A / 210A). On the Vbus (24V-45V) there are 4 big capacitor (10mF)…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA281 Hi, Could you please help me with an application of the INA281B4? I'm using it in a high side buck convertor current sensing application and it doesn't seem to like the common mode range even…
Part Number: INA281-Q1 Other Parts Discussed in Thread: INA193 , INA281 Please let us know the reason why IB and Iq values of this part are larger that INA193-Q1.
