The number 741 indicates that this operational amplifier IC has 7 functional pins, 4 pins capable of taking input and 1 output pin. TI is a global leader in the production of analog and digital signal processing (DSP) integrated circuits, as well as embedded. It was founded in 1930 and is headquartered in Dallas, Texas. Examples are the 741 and 411 models which we use in lab.

It was first manufactured by Fairchild semiconductors in the year 1963. Texas Instruments (TI) is a publicly traded company that designs and manufactures semiconductor and computer technology products. The op-amp is in essence a dierential amplifer of the type we discussed in Section 5.7 with the renements we discussed (current source load, follower output stage), plus more, all nicely debugged, characterized, and packaged for use. The LM741 series are general purpose operational amplifi- ers which feature improved performance over. Finally, when the potentiometer is set to the mid-point, k 0.5 and Av 0. When k 0, then Av R2 / R1, or maximum inverting gain. If k 1, then Av R2 / R1, or maximum noninverting gain. Texas Instruments LM741 series are general-purpose operational amplifiers which feature improved performance over industry standards like the LM709. It has 7 functional pins, 4 pins capable of taking input and 1 pin for output. Texas Instruments offers its LM741 operational amplifiers for a wide range of analog applications. It can be used to regulate power supplies, made into a simple signal generator, used as an oscillator. The potentiometer sets k from 0 through 1. IC 741 is a monolithic IC, comprising of a general purpose Operational Amplifier. The 741 op-amp is a general purpose amplifier. It also features short circuit protection and internal frequency compensation circuits built in it. The 741 Op Amp IC is a monolithic integrated circuit, comprising of a general purpose Operational Amplifier. Av R2 R1(2k 1) In essence, the resistors R1 and R2 set the maximum gain.
IC 741 Op Amp can provide high voltage gain and can be operated over a wide range of voltages, which makes it the best choice for use in integrators, summing amplifiers and general feedback applications. It has a very high voltage gain, typically of the order of 105 (100dB).Īlthough they are initially designed for performing mathematical operations like addition, subtraction, integration, differentiation etc., (hence the name Operational Amplifiers), by using external components like resistors and capacitors to create a required feedback mechanism, it can also be used as an amplifier and for many other functions like filters, comparators etc. This IC 741 Op Amp is most commonly used in various electrical and. This prevents possible circuit damage to the device. \).An operational amplifier, also called as an op-amp or op amp, is an integrated circuit primarily designed for performing analogue computations. It consists of two inputs and two outputs, namely inverting and non inverting terminals. The LM741 features overload protection circuitry on the input and output.
