7.4 Device Functional Modes

The three circuit sections of the REF200 are electrically isolated from one another, using a dielectrically-isolated

fabrication process. A substrate connection is provided (pin 6), which is isolated from all circuitry. This pin should

be connected to a defined circuit potential to assure rated DC performance. The preferred connection is to the

most negative constant potential in the system. In most analog systems, this would be –VS. For best ac

performance, leave pin 6 open and leave unused sections unconnected. Figure 10 shows the simplified circuit

diagram of the REF200.
