Operational amplifier, lm741 datasheet, lm741 circuit, lm741 data sheet. Ic 741 op amp operational amplifier the 741 op amp ic is a monolithic integrated circuit, comprising of a general purpose operational amplifier. In the linear region the slope of the line relating vo to vi is very large, indeed it is equal to the open loop gain a. The amplifiers offer many features which make their applica. Ic 741 op amp basics, characteristics, pin configuration. The lm741 mil is a generalpurpose amplifier than can be used in a variety of applications and configurations. Fairchild, alldatasheet, datasheet, datasheet search site for electronic components.
The number 741 indicates that this operational amplifier ic has 7 functional pins, 4 pins capable of taking input and 1 output pin. In this configuration, the output signal is in phase with the input not inverted as in the inverting amplifier configuration, the input impedance of the. Modern integrated circuit technology and large scale production techniques have brought down the prices of such amplifiers within reach of all amateurs, experimenters and hobbyists. The circuitry that makes up an op amp consists of transistors, resistors, diodes, and a couple capacitors. Working of the circuit is simple, basically this circuit generates a square wave at the output if op amp is in working condition, resulting a blinking led. Offset null is a calibration feature of the op amp.
They are direct, plugin replacements for the 709c, lm201, mc1439 and 748 in most applications. A collection of amp applications application note an106. Single operational amplifier, lm741 datasheet, lm741 circuit, lm741 data sheet. It was first manufactured by fairchild semiconductors in the year 1963.

An operational amplifier, often referred to as an op amp, is a very high gain performance amplifier designed to amplify ac and dc signal voltages. One common configuration is in a noninverting amplifier configuration. The op amp is so sensitive to the input voltage that at times the output will generate a signal even when there is no intentional input. Lm741 operational amplifier general description the lm741 series are general purpose operational amplifiers which feature improved performance over industry standards like the lm709. A collection of amp applications application note an106 created date. To avoid this condition for certain applications, offset null pins, pin 1 and pin 5 are provided.
