Analog & Mixed Signal ICs
Mixed-signal ICs are integrated circuits that contain both analog and digital circuitry on one chip. An analog signal is a continuous time-varying signal, and a digital signal is a noncontinuous signal that takes on only a finite number of values. Mixed signal ICs make use of both of these types of signals. Mixed-signal ICs are used in a wide variety of applications and application-specific integrated circuits (ASICs).
