This is easy to build and very useful project for hobbyists and students to learn and create op-amp-based projects. The board accommodates a single op-amp in DIP-8 package. The project provides the user with multiple choices and extensive flexibility for different applications circuits and configurations. It provides the user with many combinations for various circuit types including active filters, differential amplifiers, and external frequency compensation circuits etc. A few examples of applications circuits are given below. LM358 op-amp is the right choice to use or any DIP-8 op-amp with the same pin configuration as LM358 can be used. It supports dual supply or single supply, Jumper J1 is provided to use this board with a single supply, D1 power LED.

Note: Refer to example circuit to test the board, it is bistable multivibrator.

Credits: All example schematics are from Analog Devices application notes.
