INA780B: quiescent current

Part Number: INA780B

Tool/software:

Hello,

Our customer has a question about INA780B quiescent current of

1) Could you tell us the quiescent current test condition ? 
Although I am understadning INA780B Iq test condition below, please let me know if my understanding is incorrect.

2) Even though the datasheet soecify 750uA max at Ta=25C, are there any operating condition that the quiescent current goes higher than 750uA max ?
I am thinking that Iq is going to increased by VS going higher e.g. VS=5.5V. Please let us know, if there are any operating condition of Iq increasing higher than 750uA max.

  • Hello,

    Yes, you understand the Iq test conditions correctly.

    The Iq will change according to the typical plots in the datasheet:

    The Iq is mostly flat over the supply range. The device will display increased Iq over temperature, which is specified in the next row of the datasheet as 1 mA max.

    Let me know if you have any more questions,

    Levi DV
