Voltage rails A through C are used as voltage sources which can be connected to a precision digital to analog converter (DAC) or to an external reference input. Rail A can be connected to DAC A or to external reference A. Rail B can be connected to DAC B or to external reference B. Rail C can be connected to DAC C, external reference C, or to ground. This architecture provides for maximum flexibility. If additional output channels are required, an external switch matrix (such as the GX6616) can be used. An on board EEPROM contains the DAC’s calibration parameters and provides for enhanced accuracy.
