20 Watt Stereo Audio Amplifier using TDA2005
This is the scheme diagram of 20 Watt stereo audio amplifier which use dual IC TDA2005, one IC for left channel and the another one for right channel. Each IC will give you 20 watt output, so the output will be 2×20 Watt. The supply voltage for this circuit is 8VDC to 18VDC, use regulated… Read More »
20 Watt Audio Amplifier with LM1875
This is 20 watt audio amplifier circuit design which use IC LM1875 as main component. This circuit is simple and very easy to built. For stereo channel, you need to build the two same circuits which will amplify the both of audio channels (right and left channel). Dual polarity / symmetrical power supply required for… Read More »
Inverter 12V DC to 240V DC
This inverter 12V DC to 240V DC can be used to power electric razors, stroboscopes and flash tubes, and small fluorescent lamps from a 12 volt car battery. In contrast to the usual feedback oscillator type of inverter, the oscillator of this inverter is separate from the output stage, which allows easy adjustment of the… Read More »
Loudspeaker System Crossover Network
Building a passive crossover for a speaker involves designing a network of passive electrical components (resistors, capacitors, and inductors) that split an audio signal into different frequency ranges and direct those ranges to the appropriate drivers (such as woofers, midrange speakers, and tweeters) in a multi-driver speaker system.. Here the simple passive schematic diagram of… Read More »
