    Hello,

    Thanks for reaching out. It depends on how you would like to set up the device. Section 8.1 Application Information in the DRV2700 data sheet has various diagrams for different applications. For it example, it has AC-Coupled DAC Input Application, Filtered AC Coupled Single-Ended PWM Input Application, DC-Coupled DAC Input Application, and DC-Coupled Reference Input Application. It sounds like you are wanting to do a single ended input. You can connect IN- with a cap to ground and then an AC coupled signal to IN+.
