An amplifier is a circuit which can produce an output voltage, which is the product of input voltage with a value called voltage gain. An op-amp (operational amplifier) is a kind of amplifier circuit which can perform an operation (addition, subtraction etc.) on the input voltages, apart from simply amplifying the input. It is an electronic…
Differential amplifier using IC741
This project will detail about working of differential amplifier in a circuit. Many electronic devices use differential amplifier internally. A differential [[wysiwyg_imageupload::]]amplifier is a type of electronic amplifier that multiplies the difference between two inputs by some constant factor (the differential gain). In the circuit explained here, differential amplifier has been created using IC 741. This circuit based project can be used to understand working of a differential amplifier circuit. A differential amplifier circuit is an amplifier circuit which amplifies the voltage difference between two inputs. Keep on reading to find out how the circuit is assembled and how it works.
Inverting amplifier using 741
This project on Inverting amplifier circuit demonstrates the principle of operation of opamp as inverting amplifier using 741. By this circuit we can amplify [[wysiwyg_imageupload::]]both AC and DC. If voltage is AC then its phase also changes; it gets inverted or is changed by 180 degree. Opamp is used to get high gains and can be used as amplifier in any circuit. It is due to prime importance in applicative and developmental areas that inverting configuration is a must for every electronic enthusiast and covering the basics of the inverting amplifier is this electronic circuit tutorial. IC 741 is used most of the time to play the role of the amplifier. This is a comparator IC and can be used in non-inverting configuration too depending upon how the power supply is connected. Keep on reading to find out how the circuit is constructed and what makes it work.
