Resistor trimming

WebTo achieve a variable trim range, an external resistor network must be added. (Figure 5.1) Example 1: For trimming –10% to +10% with a standard off-the-shelf 10kΩ potentiometer (R7), values for resistors R6 and R8 need to be calculated. Resistor R6 limits the trim down range. For a given percentage, its value is independent of output voltage. WebPassive trimming involves the adjustment of a single resistor to a required value, while active trimming alters the entire circuit output, traditionally voltage, switching threshold or frequency. Both can be used with all three lasers (IR, Green and UV).
