![]() Nowadays opamp is used to perform many varieties of operations such as sign changing, scale changing, scale changing, phase shifting, voltage regulation, In instrumentation, pulse generators, analog to digital and digital to analog converters, the voltage to current converters, current to voltage converters, sample and hold circuit, comparators and in control systems. Block diagram of operational amplifierĪn opamp is so named as it was originally designed to perform mathematical operations like summation, multiplication, subtraction, differentiation, integration etc. Op-amps are among the most widely used electronic devices today, this is used in consumer, industrial, and scientific devices. Typical uses of opamp are to provide voltage amplitude changes (Amplitude and polarity), oscillators, filter circuits, and many types of instrumentation circuits. And by using these feedback components with different configurations decides the mode of operation of the operational mplifier to in which mode its working. ![]() Op-amp uses some external feedback components such as resistors and capacitors with the output to input terminals for its operation. Op-amp can amplify the DC signals as well as AC signals. An operational amplifier contains a number of differential amplifier stages to achieve a very high voltage gain. Opamp is basically a multistage, direct-coupled, negative feedback amplifier that uses voltage shunt feedback to provide a stabilized voltage gain. Voltage follower or Unity gain of op-ampĪn operational amplifier or op-amp is basically a multistage, very high gain amplifier having very high input impedance (typically a few Mega ohms) and low output impedance(Less than 100 ohms) and has the capability to amplifying signals of frequency ranging from zero HZ to 1MZ.
