I'm designing a CAN-based platform using the Microchip MCP2551 transmitter. The circuit looks like that:
Notice the unconnected pin VREF. I tested the circuit on a prototype and CAN is working. What is the purpose of that pin VREF, which is described in the datasheet as voltage output reference? Could you suggest some applications using VREF? If I don't use it is it ok to left it open?
