74HC4052 Dual 4-channel analog multiplexer demultiplexer

The commutator circuit delivers low impedance gate drive to the PN4091 analog switch for both on and off drive conditions. This circuit also achieves near-ideal gate drive conditions for high-frequency signal handling by offering low AC impedance during off...

This circuit is designed to drive a total of 42 LEDs, assuming a forward voltage of approximately 2.2V per LED and a forward current of around 21mA for adequate brightness. If the specifications of the LEDs differ significantly, modifications...

Normally, an analog-to-digital converter (ADC) requires interfacing through a chip to convert analog signals into digital format. This necessitates both hardware and software, resulting in increased complexity and overall cost. The circuit presented here is configured around the ADC...

This is a nice design for people who have no tachometer in the car or on the bike. The circuit uses two ICs: an NE 555 and a CA 3140. The input of the circuit is connected to the...

A multi-channel D/A converter circuit is presented, illustrating its fundamental structure. This circuit effectively converts encoded digital signals into multiplexed analog signal outputs. The multi-channel Digital-to-Analog (D/A) converter circuit is designed to facilitate the conversion of digital signals into corresponding...

In addition to flyback transformers and microwave oven transformers (MOTs), automotive ignition coils are frequently utilized as high voltage sources by various enthusiasts. This is particularly true for the classic cylindrical ignition coils used in carbureted engines prior to...
