INA4290: Solutions for multiple current sense device with interface

Part Number: INA4290

Hi Experts,

Seeking your assistance on this query from Cx.

They are looking for a current sense multiple channel that supports digital interface, but I am only seeing multiple channels of this type in analog output (i.e. INA4290).

Now, is there any solution with in-built ADC.? Which stores the data in some registers or give some digital alert signal to the main processor. Seems like we need to use additional ADC along with INA4290.

Thank you.

Regards,
Archie A.

    Hi Archie, 

    We do have a multi-channel digital current sensor available now, the INA3221 is a 26V triple-channel digital power monitor. 

    If the max Vcm needed is >26V, or if the customer needs four-channel, they will need to use an analog current sensor in addition to a separate ADC as you mentioned.
