INA740B: Robust Design Guidance

Wayne Eckertson
Prodigy 190 points

Part Number: INA740B
Other Parts Discussed in Thread: TIDA-00302, INA210

Tool/software:

While researching current sensors, I ran across the Transient Robustness for Current Shunt Monitor TIDA-00302 ap note.  Does this ap note apply to the INA740B?  Are there any other design recommendations outside of the datasheet?

    Hello Wayne,

    Yes, you can use the concepts of that design with the INA740B by adding the circuitry in between the SH± and IN±. Due to a different architecture in the INA740B and the INA210, you will also want to add a capacitor (~10nF) across the IN+ and IN- pins of the device (on the IN± pin side of the rest of the circuitry). 

    Regards,
