Types of Buffered, Voltage DAC Outputs   Figure 1 shows three common types of buffered, voltage output DACs. The first has a fixed-gain defined by an internal resistor raTIo (typically +1.0, +1.638, or +2.0V/V), and no provision for adjusTIng the offset. The second type also uses internal resistors to set a fixed gain, but the normally grounded resistor tap in the non-inverTIng gain op amp topology is brought to an external pin allowing offset adjustment. The final output type is force/sense, which provides a pin connecTIng directly to the inverting terminal of the output op amp, yielding the most flexibility.
