The difference between operational amplifier and analog IC

[rinaishlene]

Hi,

May I know what is the difference between operational amplifier and analog IC?

maybe this wont answer your question completely but i will give it a try

an analog IC is used in those cases when u have to do with analog signals/voltage like some circuits ex. comparator,
operational amp, poweramp, HF/MF circuits, timers IC, regulator IC, or in reality those circuits that works with analog
types of signals doesnt have to be an amplifier can be any type of circuit, a general view of op amps is that they
have high input impedance and high and very high amlification, these can also be used in many different ways as well.

Basically, there is no difference. The operational amplifier is designed to handle analog signals as long as you do not overdrive it. This enables us to do a number of operations (log, antilog, invert,rectify, add, subtract etc.) on analog signals (i.e. signals which vary continuously). If you overdrive the opamp, then you can use it with digital signals too, though nobody will prefer that. There are much better options for digital signals.

The simplest answer is, an OPAMP is an analog IC.

OP-AMP is an analog IC and from its name (operational amplifier) it can do many analog operations like (add,sub, invert ,.....) and that depends on it's mode of connection....

erm..a op amp may be analogue in design but it is frequently used in digital equipment, i.e. analog to digital converters , esp 'flash' conversion... the question asked is difficult to answer because it is phrased badly..
a op amp is as different to a 'analogue ic' as a apple is different to an orange, a analogue ic may contain op amps, but it will also have other 'stuff'... an op amp is just that..no more
