INA286-Q1: What's the current consumption for the IN286 REF1 and REF2

HI team,

My customer is asking the current consumption on the INA286 REF1 and REF2 pin, is there any spec?

Also what's the current consumption for the V+?

Thanks

    Hi,

    There is a spec for supply current consumption in the datasheet:

    In addition, it varies with supply voltage level:

    Unfortunately there is not s spec for REF1/2 current, however we can guesstimate. When tied together and driven by an external reference source, the total current consumed by the REF pins will vary depending on the reference voltage level (0V to 9V). But it should be below ±20uA.
