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 SOT23-5 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 application circuits are given below. LM321 op-amp is the right choice to use for this board or any SOT23-5 OPAMP with the same pin configuration as LM321 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 a bistable multivibrator, with single supply Jumper J1 closed.

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