  1. IC741 Operational Amplifier M.S.P.V.L Polytechnic College Pavoorchatram www.ustudy.in

  2. 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

  3. 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

  6. 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

  7. Internal circuitry of 741 OP-AMP www.ustudy.in

  8. Bandwidth and Gain of 741 www.ustudy.in

  9. 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

  11. 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
