An op amp is a high gain differential amp that can be configured in a myriad of ways, yet most op amps do not have the current drive of a LM386 as in a audio amp.

    As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be placed between pins 1 and 5 to modify the … This project shows how to build an Audio amplifier based on LM386 IC. The circuit is very simple and construction is easy on a breadboard. The LM386 IC is unique in that the gain can be modified by changing Resistor R2 and Capacitor C2. This configuration will give us a gain of 20. By removing R2 and connecting C2 across pins 1 and 8, we can increase the gain to 200.

    The LM386M-1 and LM386MX-1 are power amplifiers designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200.

Here's a cut/paste from another forum (elec-tech-online): if i were to design a discrete op amp, it would be very similar to a power amp design, except for the output stage, which would be just two small transistors for the op amp, but as many as 3 pairs of successively larger transistors (usually complementary

    \$\begingroup\$ The 741 is (a very old design) op amp and is not an audio amp like the lm386 - it cannot drive enough current to operate an 8 ohm speaker. If the LM 386 gain is too much add a volume control (potentiometer) before the amp to reduce the input signal. \$\endgroup\$ – JIm Dearden Oct 5 … Op-amp Basics (part 1): Operational amplifiers (op-amps) are some of the most important, widely used, and versatile circuits in use today.
