Introduction

TSL1018IFT is a high-performance, highly-integrated video amplifier designed for operating video signals up to 240MHz. With its low distortion, low input capacitance, and high frequency response, the TSL1018IFT offers a perfect solution for cost-sensitive applications demanding superior video performance. This article examines the application field and working principle of the TSL1018IFT video amplifier.

Application Field

The TSL1018IFT is a high-performance linear amplifier designed for video amplification applications. It is widely used in various video systems to amplify video signals for various video sources such as video cameras, DVD players, video monitors, and televisions. It is used to improve the performance of low-level video signals, optimize the viewing angle, and reduce unwanted noise or ghosting in the picture. It is also used to supply current and power to other video components such as deflection coils, yoke coils, and many other types of stabilizing circuits.

Working Principle

The TSL1018IFT video amplifier consists of two identical monolithic video amplifiers (VMAs): the input amplifier and the output amplifier. The input amplifier performs the initial amplification and filters out unwanted signals. The output amplifier amplifies the filtered signals to the required level and supplies power to the other video components.The input amplifier uses common-mode feedback to improve its high-frequency response, while a differential pair of transistors provides unity gain-bandwidth of up to 240MHz. The amplifier has a number of stages of gain that are chosen to suit the application by means of an on-chip dip switch. The output amplifier is a complementary-symmetry Class AB amplifier with a gain of up to 20dB. It uses a local feedback loop to improve its stability and frequency response.The TSL1018IFT is powered by a single 5V power supply and the amplifier can be operated in a wide range of temperatures (-40°C to +105°C). The amplifier has been designed for use in high-end audio-video installations and is protected from short-circuit, surge, and over-current conditions.

Conclusion

The TSL1018IFT video amplifier is a highly reliable and versatile amplifier designed for use in various video applications. Its high-frequency response, low distortion, and low input capacitance make it an ideal choice for applications demanding superior video performance. It is powered by a single 5V power supply and can handle a wide range of temperatures. Its on-chip dip switch allows for fine-tuning of the gain stages to optimize the performance of the particular application. Thus, the TSL1018IFT is an excellent choice for applications demanding high-quality linear video performance.
