What does DAC stand for in the context of actuators?

In the context of actuators, DAC stands for Digital to Analog Converter. This device is essential for processing signals in various electronics and automation systems. Actuators often require an analog signal to operate because they usually respond to continuous signals, such as varying voltage levels. The DAC takes a digital signal—composed of discrete binary values—and translates it into a continuous analog signal that the actuator can effectively use to move or control physical systems.

The functions of DACs are critical in systems where control signals must be converted from a digital format, such as those coming from microcontrollers or computers, into an analog format suitable for motors, valves, or other mechanical devices. This conversion is crucial for ensuring that the actuator operates smoothly and accurately according to the commands received from its controlling unit.
