Both. An IC (integrated Circuit) is a compact form of several electronic circuits. These circuits may be analog or digital.
An IC can be either an analog device or a digital device. Today, in early 2014, I think it's accurate to say that the vast majority of integrated circuits being manufactured and installed in electronic things now are digital.
An antenna is analog it is not classified as being a digital device.

DAC - Digital to Analog ConverterADC - Analog to Digital Converter
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
An analog-to-digital converter is a device which converts an infinite resolution analog signal to a finite resolution digital signal.
You can use it in both analog and digital circuits but it is considered as a digital device.
a device/circuit that takes a multiplexed signal and splits it back out to the original separate signals. note: there are also analog demultiplexers.
