DRV8305 : SNx connected to GND

Hi Shirai-san,

Is there a particular reason for this request? For best common mode rejection we recommend connecting the amplifier in inverting configuration with SP to GND and SN to other side of the shunt resistor.

Hi Nick-san,

Thank you for reply.
When we designed the schematic, we mistook then SNx is connected to GND and SPx is connected to the other side of shunt registers in our circuit board.
I will move motor with the circuit board for motor test...
If there is not so huge problem, I'd like to use this circuit board when I develop software.
(When we build the new circuit board in the future, SPx will be connected to GND.)

Thank you in advance,
Shirai

I think this should be OK for initial evaluation and software development.
