... U U APPLICATIO S I FOR ATIO Introduction The LT1996 may be the last op amp you ever have to stock. Because it provides you with several precision matched resistors, you can easily configure it into several different classical gain circuits without adding external compo- nents. The several pages of simple circuits in this data sheet demonstrate just how easy the LT1996 is to use ...

... Difference Amplifier: Additional Integer Gains Using Cross-Coupling Figure 12 shows the basic difference amplifier as well as the LT1996 in a difference gain of 27. But notice the effect of the additional dashed connections. This is referred to as “cross-coupling” and has the effect of reducing the differ- ential gain from 27 to 18. Using this method, additional integer gains are achievable, as shown in Table 5 below ...
