Alpha Operational Amplifier Kit by Unilab

The Alpha Electronics Kits have been designed to incorporate electronic applications into Physics lessons. The various boards offer versatility and cover a wide range of topics. Both student and teacher notes are included.

• Each kit is suitable for one student or lab group working from the student notes.

Operational Amplifiers are common in many electronic devices. They amplify minute signals e.g. from a microphone to make them suitable for input to a power amplifier, or the signals from ECG sensors, to enable them to be displayed on a screen.

This Alpha Operational Amplifier Kit gives students an understanding of operational amplifiers, including input impedance and feedback, gain, amplification of d.c. and a.c. signals, saturation, differential mode, the use of a bridge circuit to detect and amplify very small changes - this has applications in the creation of sensors such as strain gauges. When used with a microphone, an Alpha Power Amplifier and small loudspeaker, a two stage audio amplifier can be constructed.

The manual (on CD) includes suggestions for extension work that involves discrete components and op amps, built on breadboard.
