- Analog Signal Conditioning for Accurate Measurements
Do you need some sort of circuit between your sensor and an analog-to-digital converter? Before you make any connections, get the electrical specifications for the analog-to-digital converter (ADC) and for the sensor or sensors in your system. The explanation in this white paper will help you understand what you need and why you need it.
- Differential Nonlinearity in Analog Measurements
In most applications, linearity in analog measurements is more important than absolute precision. Ideally, in an A/D converter the digital value ramps smoothly as the input increases across its entire range. The deviation from ideal operation is a function of each ADCâs particular architecture and is expressed as differential nonlinearity (DNL). Find out how DNL is determined and the effect it has on making accurate measurements in this white paper.
- Determining an Effective Analog Sampling Rate
How often should your equipment make measurements? This question often arises when people draft plans to automatically measure a physical quantity such as temperature, pressure, acidity, liquid level, and so on. You can approach this problem in several ways, from an educated guess to a mathematical analysis of your system. The examples in this white paper use temperature measurements because people measure temperature more than any other physical characteristic.
