DRV595: Differential Input

Part Number: DRV595

Hello-

I am using DRV595 to drive TEC. In the datasheet, it says "To use the DRV595 with a single-ended source, use a voltage divider to bias IN- to 3.0V, and apply the single-ended signal to IN+." Is there a reason why it needs to be specifically biased at 3V? Will it be okay to bias IN- to 1.25V and apply the single-ended signal to IN+?

Thanks,
