Analog circuits have had their day; everything is digital now. However, here’s a simple analog circuit built with one good, old, but still available pulse-width-modulating regulator chip. The automatic DC heater controller circuit introduced ...
The circuit presented here is a 3 W stereo audio amplifier with memory UP/DOWN volume control. The project is based on PAM8408 IC from Diode Incorp which is a filter-less class-D amplifier with high SNR and Differential input which helps eliminate ...
This project is a simple, low-voltage push-pull PWM controller using the TI LM5032 chip and two MOSFETs. It's suitable for applications like DC-DC converters or Tesla coil drivers. Frequency, current sensing, and soft start are configured via ...
An inexpensive piezoelectric wafer is used to detect vibration and when the vibration is sufficient a switch is activated. Materials on the topic Datasheet Texas Instruments CD4069UB discovercircuits.com
There are times when you would like to control a DC motor using a simple +5 V logic swing signal. The circuit below performs this feat and also includes an automatic motor braking circuit. When the input logic signal swings from 0 V to +5 V, the ...
The circuit below can switch up to 4 Amps of current with a peak voltage up to 20 V. It is fully isolated using two inexpensive red LEDs. One LED forms a red light source, which illuminates a second red LED. The circuit takes advantage of the 1.5 V ...
This circuit uses a few FETs and logic devices to down convert a DC voltage to about one half its value. Materials on the topic Datasheet Fairchild MM74C14 Datasheet Diodes ZVN2106A Datasheet Diodes ZVP2106A discovercircuits.com
This circuit can produce high speed output signals with fast rise and fall times. The unique charge pump action allows the voltage of the upper P-ch device to range from millivolts to hundreds of volts. The output current is only limited by the ...
This simple circuit can protect a sensitive electronic circuit from an accidental connection of a battery with a reversed polarity. The N-channel FET connects the electronic device to the battery only when the polarity is correct. The circuit shown ...
If your favorite tool is a hammer, every problem will look like a nail. Abraham Maslow Given how often I tinker with the LM555 and LMC555 analog timers, Maslow might have written that famous aphorism specifically for me. And it. Well, here I go ...
