The HV2070/AJA are a special type of analog switch used extensively in the interface and analog switching industry. They are a single chip solution for fast and precise analog switching, allowing for high frequency switching of high precision signals. They are capable of switching between two differential output lines at speeds up to 33MHz, with a very low power consumption, making them ideal for applications where power and speed is of utmost importance. Additionally, they can also be used in applications that require high isolation between the switching paths, such as medical and industrial applications.

The HV2070/AJA application field covers the use for switching of audio, video and RF (radio frequency) signals. Due to their high frequency and low power consumption, they are the ideal solutions for switching high-precision signals that are used in television broadcasting and digital audio recording. Additionally, they can provide a very stable switching path when used in audio and video applications, eliminating any potential degradation of the signal that could occur due to imperfection in the switch’s design.

The working principle behind the HV2070/AJA is quite simple. They are driven by a single input voltage, which is typically 12 volts. This voltage is then stepped down with the help of an RF amplifier, allowing for a very low power consumption and high frequency switching. The analog switch then consists of two differential output lines; one for positive and one for negative switching. Depending on the polarity of the input voltage, the analog switch will either provide a high or low output voltage, depending on the analog circuit being used.

The HV2070/AJA is a very versatile switch, offering a variety of features and functions. The most important feature of this switch is the ability to operate across a wide frequency range and the ability to switch fast, with very low power consumption. This makes them ideal for applications that require a high performance and reliability, such as in television broadcasting and digital audio recording. Additionally, with their very low power consumption, they are ideal for applications that require a high isolation between the switching paths, such as medical and industrial applications.

In conclusion, the HV2070/AJA is a highly regarded and widely used switch, thanks to its ability to offer high performance, reliability, and power efficiency. Its use in audio, video, and RF applications make it a versatile solution for switching high precision signals, and its low power consumption makes it a desirable choice for applications that require a high degree of isolation between the switching paths.
