Amplifiers, Waveform Generators and Other Low-cost IC Projects

Inexpensive and easy to use, the CD4066 integrated circuit has more practical applications than many hobbyists realize. Unlike most digital devices, it can be employed to switch either digital or analogue signals, so the CD4066 can be used in everything from digitally-controlled analogue amplifiers, signal generators, timers and filters to music synthesizer modules, LED displays, flashers and burglar alarms. In this text, Delton T. Horn demonstrates the versatility of the CD4066 through many projects. The illustrations show readers how to put the CD4066 to work in: programmable resistors, capacitors and transistors; programmable multi-input and -output amplifiers; short- and long-pattern sequential tone generators; programmable low-, high- and band-pass filters; digitally-controlled chimes and drums; count up/down timers; pseudo-random flashers; burglar-alarm systems; and infrared remote-control transmitters and receivers. Each project contains a complete parts list, schematic diagram and a parts diagram where necessary. Tips on how to customize the CD4066 IC to meet the needs of individual applications are also included.
