This is easy to build and very useful project for hobbyists and students to learn and create OPAMP-based projects. The project accommodates a single OPAMP in the MSOP8 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. A few examples of application circuits are given below. OP777 op-amp is the right choice to use or any other MSOP8 op-amp with the same pin configuration as OP777 can be used. It supports dual supply or single supply, Jumper J1 is provided to use this board with a single supply, D1 is the power LED.”
