INA210-Q1: UQFN package IN+/- connection

Mike Yu

Part Number: INA210-Q1

Hi Team,

Just curious that compare with SC70 package why did the UQFN package has two pins of IN+ and IN-?

The customer should connect 2 and pin3, pin4 and pin5 directly, right? Is there any thing need to notice when they are doing the layout? Thank you.

Best regards,

Mike

Hi Mike,

Customer should tie the duplicated input pins together, as mentioned by in the datasheet page 15:

Hi Guang,

Get it, is there any thing need to notice when doing the layout? Or just do the Kelvin connection. Thank you.

Best regards,

Mike

Hi Mike,

It should be good to do Kelvin connection to the shunt resistor. Short the identical input pins at the device. Please note that UQFN is not available for q1 grade.
