Why are op-amps named IC 741?

Answer 1

The initials, IC, simply mean that the op-amp is made inside an integrated circuit. Op-amps have a total of 8 pins, and out of those 8 pins, 1 is inactive( pin no. 8) and 7 are active. 4 of the pins (2, 3, 4, and 7) supply the output, and one of the pins (pin 6) observes the output. So 7 means 7 active pins, 4 means 4 inputs, and 1 means 1 output.

Answer 2

The 741 is a general purpose operational amplifier which features improved performance over industry standards like the LM709. They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications.

The offset voltage and offset current are guaranteed over the entire common mode range. The amplifiers also offer many features which make their application nearly fool-proof; overload protection on the input and output, no latch-up when the common mode range is exceeded, as well as freedom from oscillations.

Answer 3

it has 7 active pins 1 not connected. and 4 pins where we apply inputs(2,3,4,7)

741 is simply an arbitrarily assigned part number for a particular type of opamp. it has no meaning encoded in it.

Answer 4

The 741 does not have the high frequency response to function in an RF circuit such as a radio.
