The THS7315D Integrated Circuit (IC) is a video amplifier and module containing three independent high-performance video amplifiers. It is designed and optimized for composite video-signal applications, providing improved picture performance with low power consumption and a small form factor. Featuring high gain, low-noise operation, and excellent large-signal bandwidth, it is suited for broadcast, security and surveillance, automotive, and other video-processing applications. This article will provide an overview of the THS7315D’s application field and working principle.

Application Field

The THS7315D is a 1.8V low-voltage operation, three-channel video amplifier IC targeted at high-performance video-processing applications. It supports composite video-signal applications, providing improved picture performance with low power consumption and a small form factor. Suitable for broadcast, security and surveillance, automotive, and other video-processing applications, its design features high gain, low-noise operation, and excellent large-signal bandwidth. It includes four low-voltage op-amp blocks that enable four simultaneous operation stages to fulfill the highest performance demands. It is optimized for analog and digital video systems, giving improved picture performance and system cost reduction compared to alternative solutions.

Working Principle

The THS7315D is an integrated video amplifier and module containing three independent high-performance video amplifiers. It is based on an architecture with four separate video-processing sections, each with independent gain and offset controls to meet the performance requirements of composite video-signal applications. The four core video-processing amplifiers achieve low-noise operation, high gain, and wide bandwidth. Furthermore, the THS7315D also offers several techniques to further reduce the amount of noise, ripple, and interference in a signal, helping the users to achieve the best possible picture performance.

The modulator section contains three independent amplifier sections for RGB signals that are connected in a push–pull configuration. The purpose of the modulator is to dampen the input signal as necessary, providing an enhanced drive capability for the internal amplifiers. The modulator is controlled by the modulator enable pin, and the output of the modulator section is routed through an adjustable gain amplifier, which further boosts the signal gain if necessary. The amplifier can be enabled or disabled by the amplifier enable pin.

The amplifier section contains three independent amplifier stages, with each stage providing the necessary gain, offset, bipass, and feedback. The amplifier section is controlled by the amplifier enable pin and the feedback enable pin, allowing the user to adjust the gain and offset of each amplifier independently. The output of the amplifier section is then routed through an adjustable bypass stage, allowing the user to fine-tune the frequency response of the amplifier.

The THS7315D also contains several techniques to further reduce the amount of noise and interference in a signal, such as the integrated low-pass filter, the zero-phase shift filter, and the peak clipper. The zero-phase shift filter reduces the amount of noise in the signal by drastically reducing the number of harmonic signals in the output. The low-pass filter removes high-frequency components to reduce the amount of noise in the signal, while the peak clipper adjusts the waveform to ensure the signal does not exceed the nominal supply voltage. All of these techniques help to ensure the highest possible picture performance.

The THS7315D is an ideal solution for high-performance video-processing applications due to its integrated design, low power consumption, and small form factor. It offers improved picture performance compared to alternative solutions and provides the necessary gain, offset, and feedback to fulfill the highest performance demands. Its techniques for reducing the amount of noise, ripple, and interference further ensure that the user can achieve the best possible picture performance.
