NJM2268V Application Field and Working Principle

The NJM2268V is a linear-amplifier module designed for use in video applications. This module is designed to provide low-noise amplification of a video signal. It is suitable for applications such as video drivers and televisions.

The NJM2268V is a dual-channel amplifier module. It consists of two separate amplifier circuits, each of which is designed to amplify small input signals. Each amplifier circuit is capable of amplifying an input video signal from up to 5 mV peak-to-peak to up to 1 V peak-to-peak. The module also features an adjustable gain and a wide range of output voltage levels.

Working Principle

The working principle of the NJM2268V is fairly simple. The module is designed to amplify an input video signal using an integrated circuit (IC). This IC is a discrete-design video amplifier. It contains two different amplifier circuits, each of which amplifies an input video signal independently. The gain of both amplifier circuits can be adjusted separately to obtain different output voltage levels.

The input video signal is first divided into two parts, with each part being amplified by a separate amplifier circuit. As the amplified signals are combined, they are added together so that the sum of the two amplified signals is equal to the original input signal. This is referred to as the "summing frame" of the amplifier.

The NJM2268V also features an adjustable gain control. This allows the user to adjust the amplifier\'s gain to obtain different output voltage levels. The gain is typically adjusted by changing the value of an external resistor. The gain range of the NJM2268V is typically between 20 and 40 dB.

Conclusion

The NJM2268V is a linear-amplifier module designed for use in video applications. It is a dual-channel amplifier module that consists of two independent amplifier circuits. Each amplifier circuit is capable of amplifying an input signal from up to 5 mV peak-to-peak to up to 1 V peak-to-peak. The module also features an adjustable gain and a wide range of output voltage levels. The working principle of the NJM2268V is fairly simple and is based on a discrete-design video amplifier IC.
