INA199: INA199 / Output pulse at V+ start-up

Part Number: INA199

Hi,

Please let me ask about the behavior at V+ start-up. I found the output pulse voltage at V+ start-up as attached. Supply voltage power-up after V+ as attached. I'd like to know if this pulse voltage on OUT at V+ start-up is normal behavior.

Your comment will be appreciated.

Best Regards,

    Hello Satoshi-san,

    Yes, this is a normal startup response for the INA199.  Please refer to Figure 18 from the datasheet.  I have circled the spike in red in the figure below.
