• Use SW3 to vary the trace

length to BTN4

• Use SW1 to vary an external

capacitor in parallel with the

trace to BTN2

• Place the provided 1 mm

SmartSense

Auto-Tuning:

Easily evaluate the SmartSense

Auto-Tuning algorithm, which continuously compensates for system,

manufacturing, and environmental changes. Easily evaluate the SmartSense algorithm by varying

the parasitic capacitance in one of three ways:
