The following  are the basic specifications of IC 741 :

• Power supply : Requires a minimum voltage of 5V and can withstand up to18V
• Input impedance : About 2 MW
• Output impedance : About 75 D
• Voltage gain : 200,000 for low frequencies (200V mV)
• Maximum output current : 20 mA recommended  
• Output load : Greater than 2 KB
• Input offset : Ranges between 2 mV and 6 mV
• Slew rate: 0.5V/qS (It  is  the rate at which an Op-Amp can detect voltage changes)

Applications:
Below are the applications of  IC 741  Op-Amp across different use cases.

• Amplifiers: 741IC is mostly used to amplify signals of varying frequencies ranging from DC to higher radio frequencies. It is also used in frequency selective amplifiers which tilter out signals of unwanted frequencies, E.g  tone  control  systems  in  stereo  and  Hi -Fi systems.
• Computational : Many electronic circuits that perform mathematical operations like integration. differentiation, summers, etc. use 741 Op-Amp.
• Rectifiers: Ordinary diodes used in rectifiers  have  voltage  drop  across  them which makes it unsuitable for high accuracy signal rectificrs. The 741IC can  be confi gured to perform as an ideal diode i.e., with no voltage drop at all and can be used in precise rectifier circuits. Oscillators: Op-Amp  IC  741  is  used  as an oscillator in  function generators to create different output waveforms   like sinusoidal, square, triangular etc.  It is also used in Pulse Width Modulators (PWM generators)
• Comparators : The 741IC can be  used to compare voltage signals and determine if they are almost 01 the same voltage. This can be used in voltage regulators and signal comparators.
