The NJM2574 is a Low Voltage Video Amplifier contained LPF circuit75 driver and internal CLAMP/BIAS SWLPF/through SW to connect TV monitor directly. The input composite signal. (0. 5Vpp) The mute circuit with power save function is suitable for low power.... -
The NJM2670 is a general-purpose 60V dual H-bridge drive IC. It consists of a pair of H-bridgesa thermal shut down circuit and its alarm output. The alarm output CAN detect application problems and the system reliability will be significantly improved if.... -
This IC is a wideband RGB Video Amplifier with DC control developed for monitors. It includes three matched video amps, a differential input Comparator for brightness adjustment, and three matched DC .... -
The first versions operated from ±15V supplies, featured bandwidths of 50 MHz, and delivered slew rates in the low hundreds of volts per microsecond. Today`s fastest amplifiers run on ±5V supplies with bandwidths of 1. 4 GHz and slew rates of 6000V/ µsec..... -
This is the video amplifier circuit or the video splitter circuit, it is designed to take video signal is stronger. Compensate for the loss of signal, and is.... -
The circuit is a broad band amplifier which will take the video signals from your VCR and will amplify them sufficiently to drive up to 3 monitors, TV sets (provided that they can accept direct video signals), or other VCR ½s for recording from one video to.... -
Every electronic device that boost electrical signal can be called an amplifier. The various amplifier types only differ in some specific features such as:.... -
Gain adjustment will be more flexible if it controlled by a voltage signal, since we can use many methods to provide user interface. We can control it by a.... -
The light sources for mirror screws based on my work, consist of a dozen or more of high brightness LEDs, in colors or white, typically connected in parallel or series-parallel. Shown here are two amplifiers, capable of handling the full range of video....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
