SLVU006A Datasheet, PDF (19/28 Pages) Texas Instruments – UNIVERSAL OPERATIONAL AMPLIFIER EVALUATION MODULE

Chapter 3
Example Circuits
This chapter shows and discusses several example circuits that can be
constructed using the universal operational amplifier EVM. The circuits are all
classic designs that can be found in most operational amplifier design books.

3.1 Schematic Conventions
Figures 3–1 through 3–6 show schematics for a sampling of circuits that can
be constructed on the Universal Operational Amplifier EVM. The components
that are placed on the board are shown in bold and unused components are
blanked out. Jumpers and other changes are noted. These examples are only
a few of the many circuits that can be built on the EVM.
