The Universal Op-Amp Development board is a general purpose blank circuit board that simplify prototyping circuits for a variety of Op-Amp circuits. The evaluation module board design allows many different circuits to be constructed easily and quickly. This board supports single SOT23-5 package. Universal single Operational Amplifier (Op-Amp) board is designed to aid in the evaluation and testing of the low voltage/low power and some precision operational amplifiers. This board will accommodate single op amp that are assembled in SOT23-5 package. It is designed to use single amplifiers. Many different circuits can be made such as inverting, non-inverting, differential-In amplifiers and low-pass, band-pass, band reject, or notch second order filters. The amplifier can be powered with single supply.  These circuits can be configured without any modifications to the board, all that is necessary is to select the correct resistors and capacitors. The other optional components can be left open or shorted depending on the configuration desired. LMV321 is an ideal op-amp for this board however other single op-amp with same package and pins configuration can be used. The LMV321 device is single, low-voltage (2.7 V to 5.5 V) operational amplifier with rail-to-rail output swing. These devices are the most cost-effective solutions for applications where low-voltage operation, space saving, and low cost are needed.
