Digital Potentiometer - X9C Practical Uses and Examples

This video shows three application examples for using the X9C digital potentiometer in a real world circuit:

1. Adjusting the gain of an op amp
2. Digital volume control circuit
3. Frequency control of an oscillator, which can be used for many things including melody synthesizers and sound effect generators.
