A Digital device is either on or off, like a light switch. An analog device is on, off, or at any point in between. A common example of an analog device is a lamp dimmer. In animation, analog movements give the fluid, life-like movements needed to bring a figure to life.

A DAC-08 Single D/A Converter takes the Digital data stored in an animation system and converts it back to an analog signal. The DAC-08 can be used when you need to control mechanical feedback (MFB) pneumatic actuators, lamp dimmers, hydraulic or pneumatic servo driver cards, and similar 0-10 volt-controlled devices.
