What is a D/A converter?

A DA converter is an electronic circuit that converts a digital signal into an analog signal. Digital devices such as personal computers, tablets, and smartphones perform various processes using digital signals. However, when outputting the result in the form of sound or light, since these are analog quantities, it is necessary to convert the digital signal into an analog signal. An analog quantity is a continuous value, and an infinite number of digits are required to strictly convert a discrete digital quantity into an analog quantity. Conversely, a circuit that converts an analog quantity into a digital quantity is called an AD converter.
