INA819: Bias current

Pol REYMOND

Part Number: INA819

Hi team,

Quick question regarding the INA819 bias current. In datasheet :
- On page 6: Ibias = 2nA max max up to 125 ° C
- On page 11, Figure 10: the bias current that extends up to several hundred nA.

I guess there is a mistake on the units in Figure 10 and we should read "pAs" and not "nAs". Can you please confirm?

Thanks

Pol.

Hi Pol,

Sorry for the delay, this one slipped. You are correct, this is a datasheet typo. It should indeed say pA, not nA. The product definer is aware of this and has added it to her list of updates.
