INA230: Power sequence Analog inputs between and Vs

Hirotaka Matsumoto

Part Number: INA230

Hi all

Would you mind if we ask INA230?

<Question1>
Is there power sequence Analog inputs between and Vs?

<Question2>
On the datasheet, there are descriptions of absolute maximum ratings;
SDA : GND – 0.3 to +6
SCL : GND – 0.3 to VS + 0.3
Does it mean SCL has diode between SCL and VS?
SDA doesn't have diode between SDA and VS, right?

Kind regards,

Hirotaka Matsumoto

GND – 0.3 to VS + 0.3

    Hi Hirotaka,

    The SCL spec is likely a typo, ie, it should be spelled exactly the same as SDA. As far as I know there is no diode to the VS pin. I don’t have a way of verifying it at this moment but will do so later. If the outcome is different, I’ll alert you in this thread.

    Regard, Guang
