Hello Team,
I would like to drive the Vref pin of the DRV8870 with an MCU DAC.
To be sure that I do not need any buffer in between to provide the right current, I would like to know if you could share a typical Bias current for the input and the impedance offered by that pin.
From the block diagram it looks that Vref is connected to an operational amplifier (as comparator), so I would assume low bias current and high impedance.
Some typical value would help.
Thanks,
SunSet
