Question

what is difference between digital IC &analog IC?

Answer 1

digitals ICs output either a high, +5v DC, or a low 0v. The outputs of digital ICs or on-off-on-on-off....etc. Analog ICs output waves in forms of sine, tri, basically anything but Square waves. Analog ICs usually used to regulate, amplify, filter, existing waves comming into its inputs. The digital ICs output a on-off signal based on what signals you give it.



Analog ICs are not absolute, they are used in almost every design. Don't know where these other people got there info from, like they are based on PCB boards, wrong, they are based on silicon wafers they look exactly like digital ICs. Sure these Analog ICs may include some digital circuityry but their output is always analog and they are used in almost EVERY electronic/electrical device. Here is a list of Analog ICs offerd by a a distributor, http://www.jameco.com/webapp/wcs/stores/servlet/CategoryDisplay?storeId=10001&catalogId=10001&langId=-1&categoryId=1015

Both analog and digital integrated circuits are made from the same components. The difference is the way the circuits are configured and used. Digital circuits have discrete input and output values, typically either on or off. So, the inputs and outputs are either high or low. The exact output value, say 0.25 or 0.5V for low or 3.4 or 3.6V for high makes no difference, both are considered a "0" or a "1". Digital circuits are stacked many bits wide to represent numbers, often 32 or 64 bits wide. Analog uses the continuous and exact value of the output, so 0.5V is twice as loud as 0.25V in audio circuits for example. Analog circuits are normally designed to be very linear, and don't work well near saturation. A 5V regulator is definitely analog. Digital circuits are normally designed to have outputs of 1 or 0 while staying out of saturation and full cutoff (fully on or off), so they can transit the voltages between 0 and 1 quickly. Newer CMOS devices are rail-to-rail, so the outputs tend to go all the way to the rail. Mixed signal chips have some analog, normally as an input or output, combined with digital circuitry (i.e. basically a computer) to process the signals.

Answer 4

Digital IC is fabricated on a silicon bed.They consists of transistors & capacitors fabricated on a semiconductor material by doping.All inputs are either 1 or 0.Outputs r also 1 or 0.

Analog IC has active components like capacitors,inductors & resistors soldered on printed circuit boards.They handle analog signals that are mostly continuous time signals.Analog ICs are completely absolute.

Answer 5

A digital IC has inputs and outpus that are either "high" (usually 5V) or "low" (usually 0V).



With an analog IC, the inputs and outputs can be any voltage or current.

Answer 6

As far as I know there is no analog IC. Digital ICs r what we use in lab.

Answer 7

Analod IC's have input in the form of AC or DC but Digital IC'S have logical input of High LEVEL and Low Level eg +5V or 0V in pulse form
