XTR305 - industrial analog signal driver with diagnostics

08.10.2018

The new XTR305 is Texas Instruments' cost-effective full-featured analog output driver for industrial instrumentation with current or voltage output.

The XTR305 is extremely simple and easy to use. Requires virtually no external components to set up and operate - just one Rgain resistor is enough to set the gain. The driver can perform both the function of a current source and the function of a voltage source. The operating mode is set digitally - by applying a logic level to the outputs M1 and M2.

The XTR305 consists of an output driver and an instrumentation amplifier, which allows the driver to be flexibly configured and the instrumentation amplifier to be used either as feedback or as an additional analog output monitor.

The XTR305 has built-in diagnostic functions - it can diagnose and signal common-mode voltage out of range at the driver input, short circuit, open or overvoltage of the analog output signal out of range, as well as driver overheating.

Digital output type setting, output driver on/off control, error flags, and current monitoring output enable diagnostics of operation parameters and algorithms for handling potential problems during operation of the device.

The XTR305 has an operating temperature range of -40...+85°C and comes in a convenient VQFN 5x5 mm package.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

The harm of music before bed 27.06.2021

Michael Scullin, professor of psychology and neuroscience at Baylor University, conducted a study on sleep patterns. In his work, Dr. Scullin studied the relationship between music indulgence before bed and the quality of sleep. The main topic for study was the phenomenon of "ear worms": obsessive repetitions of the same melody that "gets stuck" in our head and involuntarily scrolls through the brain over and over again.

Usually we can notice this during the daytime, but Dr. Scullin has proven that the same problem happens to us in our sleep. At the same time, the quality of sleep becomes worse and it does not bring the proper benefit to the body.

The scientist based his conclusions on experiments with volunteers, in which more than two hundred people participated, answering various questions about musical habits and sleep quality. All of these music lovers experienced earworm syndrome.

In addition, fifty volunteers were invited to conduct the experiment at the Neurobiology and Cognitive Research Laboratory at Baylor University. In all participants, scientists tried to induce the effect of "ear worms" in order to empirically evaluate their effect on the quality of sleep. At the same time, the activity of the brain, the work of the body and the quality of sleep were assessed using a polysomnograph.

It turned out that those who were used to listening to tunes and songs for the future to sleep in order to sleep better, constantly suffered from the phenomenon of "ear worms" and experienced problems with sleep. This refutes the common belief that music in the evening helps to fall asleep and sleep better. The brain, even during sleep, does not stop analyzing the data obtained while listening to music, which reduces the quality of rest.
