The current project needs to measure the PH value and drive a 30W DC brush motor according to the PH value. I want to make the PH measurement circuit and the motor drive circuit on a circuit board. The motor is within 20 meters from the circuit board. If the DRV8871 is used for motor control, it is not known whether the PH measurement circuit can be implemented on a circuit board. If choose DRV8871, the one-chip computer controls. How to isolate the control path, etc.
