Hello,

Can i apply high voltage eg 40V to VBUS, V+ and V- pins while leaving the INA219 unpowered Vs=0V?

Thanks.

The INA219 does not support 40 V.

The INA290's absolute maximum ratings allow this. Figures 6-17/18 include input bias current curves for V_S = 0 V.

Hi Cyril,

As Clemens has mentioned, the INA219 can only support Vcm upto 26V but the INA290 can support 40V, even when Vs=0V.

Best,
