An application note from Richtek on buck converter used in automotive application. Link here (PDF)
Automotive environment can be quite harsh and designing electronics that need to work reliable in this environment takes special care, and often requires automotive qualified parts.
When designing voltage regulators that need to step down an intermediate voltage from the car battery supply, the car battery voltage fluctuation needs to be taken into regard.
The full operating temperature range needs to be considered for all aspects of the design, and all component parameters have to be checked over temperature.
The car radio receiver is nearby, which means that any switch-mode converter radiated emission needs to be minimized to avoid switch noise being coupled into the car radio receiver.
Another application note from Analog Devices this time about the superiority of digital over mechanical potentionmenters. Link here (PDF)
Potentiometers have been widely used since the early days of electronic circuits, providing a simple way to calibrate a system, adjusting offset voltage or gain in an amplifier, tuning filters, controlling screen brightness, among other uses. Due to their physical construction, mechanical potentiometers have some limitations inherent to their nature, such as size, mechanical wear, wiper contamination, resistance drift, sensitivity to vibration, humidity, and layout inflexibility.
Digital potentiometers are designed to overcome all these problems, offering increased reliability and higher accuracy with smaller voltages glitches. The mechanical potentiometer has now been relegated to environments where the digital potentiometer cannot be a suitable replacement, such as high temperature environments or in high power applications.
Comparing both technologies is the simplest way to discern which is the optimal solution for your system.
App note from Analog Devices on robust precision signal conditioning. Link here (PDF)
Industrial measurement and control systems often need to interface to sensors while operating in noisy environments. Because sensors typically generate very small electrical signals, extracting their output from the noise can be challenging. Applying signal conditioning techniques, such as amplification and filtering, can aid in the extraction of the signal because these techniques increase the sensitivity of the system. The signal can then be scaled and shifted to take full advantage of high performance ADCs.
Old app note from Maxim Integrated about high-precision temperature measurement. Link here (PDF)
Many industrial and medical applications require temperature measurements with accuracies of ±1°C or better, performed with reasonable cost over a wide range of temperatures (-270°C to +1750°C), and often with low power consumption. Properly selected, standardized, modern thermocouples paired with high-resolution ADC data acquisition systems (DASs) can cover this wide temperature range and ensure reproducible measurements, even in the harshest industrial environments.
App note from Maxim Integrated on electronic devices sterilization. Link here (PDF)
Although there is considerable literature about sterilization methods and equipment, there is very little written about the impact of sterilization on electronics. This article compares popular sterilization methods and discusses their suitability for objects containing electronics.
