Hello,
The customer is considering DRV2700. Customers plan to connect the output of the DAC to IN + and IN- to GND. At that time, the customer would like to connect the output of the DAC to the DRV2700's IN + without AC coupling. Is there any problem?
I am looking at Figure 33. Filtered AC Coupled Single-Ended PWM Input in the DRV2700 data sheet. When connecting IN- to GND, there is C when connecting IN- to GND. Is this also necessary in this case?
In the description of the PIN function in the data sheet, IN- was NC in CONNECTION IF UNUSED. Does this mean NC if the user does not use both IN + and IN-? Is it better to do NC without connecting to GND?
Best regards,
