4.1.1 Voltage Source

The input voltage source, VIN, should be a variable DC source between 0 V and 20 V capable of supplying 10 ADC. Connect VIN to J3 as shown in Figure 4-2. The input voltage source V5IN should be variable DC source between 0 V and 5.5 V capable of supplying 1 ADC. Connect V5IN to J1 and J2 as shown in Figure 4-2.
