2.6.2 Difference Amplifiers (SOT23 and SOT-SC70)

This board supports the usage of smaller SOT23 and SOT-SC70 package difference amplifiers with associated DIP adapter boards. "SOT23 and SOT-SC70 Difference Amplifier Configurations" Figure 2-2 shows how to configure the jumpers and the associated transfer function. The exact gain depends on the ratio of resistors used in the selected difference amplifier.
