Overview
Product Description
Operational Amplifiers are key components used in electronics and are found in many (if not most) circuits today! Op-Amps can be used for amplifying voltages, comparing voltages, producing waveforms, and even convert analogue signals into digital numbers but how does an op-amp work? What components make up an op-amp? In this kit, you will build your own simple op-amp that teaches the inner workings of basic op-amps and this discrete op-amp can be used in the many basic configurations including a unity buffer, amplifier, and comparator!

Applications
- The Discrete Op-Amp is a perfect teaching tool for op-amp circuits, and the challenges they suffer due to the poor characteristics of the op-amp. However, the op-amp is still able to be used in basic op-amp configuration, and the in-depth documentation takes the reader through the purpose of every single component including the input bias, amplification, miller capacitor, and output stage. This kit is ideal for educating A-Level and above, and the few components allow for the kit to be built and tested in under an hour.
- Education and training – Useful for teaching differential amplifier stages, discrete transistor amplifiers and negative feedback, while providing practical experience with through-hole soldering, component identification and PCB assembly.
- Project integration – Suitable for projects such as Basic Audio Amplifier, Clock Source, Alarm Circuit, and other designs where the following function is useful: Discrete transistor operational-amplifier kit that exposes the internal building blocks normally hidden inside an op-amp IC
