INA169NA Supply Current Spec.

Other Parts Discussed in Thread: INA169

Dear Support,

Hello, this is from TI Taiwan NTW sales team FAE Wei-Hao.

The INA169 datasheet did not specify the supply current ICC of INA169 when inputs are applied, we can only find the quiescent current is 60 uA.

Our customer would like to know about the supply current for their design purposes.

Please provide this information to us, thank you very much for your support.

Best Regards,

Wei-Hao

Hi Wei,

Perhaps you are looking for the Input bias current? If so, it is 10uA (typ).

Dear Mayrim,

Thanks for your reply, but I am not looking for the input bias current.

Our customer would like to know how much current of INA169 will draw from the VCC under normal operating point i.e when inputs are applied. We can only find the quiescent current which is when VSENSE = 0, IO = 0.

Thank you for your support.

Best Regards,

Wei-Hao Chen

Hi Wei,

Sorry I misunderstood. Unfortunately we don't collect the current in the supply pin with different shunt voltage values.

Dear Mayrim,

Is there any chance if BU team can verify this for us? or any sorts of technical document we can provide to our customers? Our customer is from Delta Electronics.

Thank your for your kind assistance.

Best Regards,

Wei-Hao
