Class G audio power amplifier uses two (or more) separate voltage supplies with different levels, take the benefit of AB class amplifier when operated its almost full signal swing. With two different level of supply voltage, the efficiency is significantly improved while maintaining the best accuracy (low distortion) of linear amplifier. The LM48824 is a Class G, ground-referenced stereo headphone […]

We can control medium power load, such as AC motors in home appliances, using ACST12 devices. Because of it’s thermal and turn off commutation performances, this device is able to drive an inductive load up to 12 A with no turn if additional snubber. High thermal performances in static and transient modes such as the compressor inrush current or high […]

Sometimes, there are unexpected solenoid and excessive corrosion occurs on current sense circuit. Corrosive effects can be occurred because of the differential voltage between the ground and the load. To reduce that possibility, the shunt and the switch are placed on the high side. When switch is off, the battery is removed from the load, it will avoid damage from […]

An AD8205 can be used to make a high-side current sense with a low side switch. Besides AD8205, an inductive load (solenoid) and a resistive shunt are added in this circuit. The resistive shunt is placed on high-side and the switch is placed on low-side, so that all current measurements, including the the re-circulation current, can be done because when […]

This is Powerline Audio Transmission circuit using LM1893. This circuit uses LM1893 that is designed to allow analog data reception and transmission. The carrier is modulated by base-band audio-bandwidth signals FM passing through the tuned transformer onto the power line. The receiver PLL will demodulates the modulated carrier linearly. Here is the schematic diagram of the circuit: External audio amplification […]

Light Bulb that are compared in this video are standard Light Bulb, Compact Fluorescent Lamp, and LED light bulb. In this video, the power of three kinds Light Bulb are compared by multiplying the voltage with the current. To […]
Read moreIt’s common if Air conditioner is found in every house In hot country because it’s difficult to survive in hot country without Air conditioner. Air conditioner is an electronic tool that is used to regulate the temperature in the room. This video shows how the air conditioner works. The basic idea of air conditioner is evaporation with a liquid evaporates […]
