Part Number: DRV8870

Hello,

Our customer use the DRV8870.

The customer configure the voltage of VREF using resistive divider,

so they want to know the input current of the VREF pin.

How about the input bias current of the VREF pin?

Best Regards,

Hi Aoyama-san,

The designer expects a typical value of tens of nA input current. This should translate to >10M.
