The first section includes a transistor based differential amplifier and allows the general and full study of the input stage of a monolithic operational amplifier.
The concepts of inverting and non‐inverting inputs, common mode and differential amplification and common mode feedback are considered.
The second section shows three different monolithic operational amplifiers and a set of active and passive components, allowing to check and to compare the features of the three amplifiers and the study of the different application fields.
The board is supplied complete with a set of stackable, plug‐in cables of suitable lengths and colours and with a training manual.
Power supply: ± 15 Vdc, 750 mA

Operational Amplifiers
The board is designed for a first approach to operational amplifiers. It is divided in two sections.
