Introduction • The 741 is the godfather of all operational amplifiers (amplifiers on a chip). • One of its advantages is that it is compensated (its frequency response is tailored) to ensure that under most curcumstances it won't produce unwanted spurious oscillations. www.ustudy.in
Inverting and Non-Inverting amplifier Inverting • If the voltage goes into pin two then it is known as an INVERTING AMPLIFIER. Non-Inverting • If the voltage goes into pin three then the circuit becomes a NON-INVERTING AMPLIFIER. www.ustudy.in

741 in 8-pin DIL (Dual In Line) pack • The 741 is usually supplied in an 8-pin ‘DIL’ (Dual In Line) or ‘DIP’ (Dual Inline Package, or sometimes Dual Inline Plastic) package with a pinout. • This has proved so popular that many other competing op-amps have adopted the same package/pinout. www.ustudy.in

LM741 • The LM741 series are general purpose operational amplifiers which feature improved performance over industry standards like the LM709. • They are direct, plug-in replacements for the 709C, LM201, MC1439 and 748 in most applications. www.ustudy.in

LM741 • The LM741C is identical to the LM741/LM741A except that the LM741C has their performance guaranteed over a 0°C to +70°C temperature range, instead of -55°C to +125°C. www.ustudy.in
