IC741 datasheet




The term operational amplier or “op-amp” refers to a class of high-gain DC coupled ampliers with two inputs and a single output. The modern integrated circuit version is typi ed by the famous 741 op-amp. Some of the general characteristics of the IC version are :

– High gain, on the order of a million
– High input imp edance, lo w output imp edance
– Used with split supply , usually +/- 15V
– Used with feedback, with gain determined by the feedback network.


Block Diagram


The operational ampli er (op-amp) was designed to perform mathematical operations. Although
now superseded by the digital computer, op-amps are a common feature of modern analog electronics.
The op-amp is constructed from several transistor stages, which commonly include a di erentialinput
stage, an intermediate-gain stage and a push-pull output stage. The di erential ampli er
consists of a matched pair of bipolar transistors or FETs. The push-pull ampli er transmits a large
current to the load and hence has a small output impedance.
