IC chips and Discrete Devices. Silicon, Germanium and Gallium Arsenide products. Diodes, Transistors and Zeners. This section has been integrated into [https://dapj.org/](https://dapj.org/) delabs will be recording chips and silicon devices that are worth studying and are being used in some designs. Some Chips get obsolete or replaced by better ones. Many remain popular for decades. Chips form the heart of any Electronic Device today. Programmable chips are very popular as we can implement logic and math functions in its firmware. Many microcontrollers come with analog inputs and outputs. These chips are complete solutions when programmed.\ \ **Related delabs Resources** - [Circuit Diagrams Archives Reference](https://www.delabs-circuits.com/cirdir/links/links1.html) - [Components Parts Kits and Materials](https://www.delabs-circuits.com/cirdir/links/links11.html) - [Mixed Circuits Analog with Digital](https://www.delabs-circuits.com/cirdir/analog/analog3.html) - [Digital Timers, Counters and Clocks](https://www.delabs-circuits.com/cirdir/digital/digital2.html) - [Tutorials on Basics and Instrumentation](https://www.delabs-circuits.com/cirdir/theory/theory5.html) - [Tutorials on Digital Electronics](https://www.delabs-circuits.com/cirdir/theory/theory6.html)
