- Figure 1. By controlling the duty cycle of a Schmitt trigger, you obtain 32 steps of brightness in an LED display
- Figure 2. The MAX5160 digital potentiometer controls the duty cycle of the Schmitt trigger
- Figure 3. The duty cycle of the Schmitt trigger is a linear function of the potentiometer's tap position
- Figure 4. Frequency also varies with the tap position, but with no effect on performance
