9 Current generators characteristics
9.1 Current setting
The current of all outputs is programmed through an external resistor connected to R-EXT
pin, as shown in Figure 15.
The curve in Figure 16 describes the relation between the current and the resistor
connected to R-EXT pin, whereas the Table 8 shows how to set some typical current values.
