App note: Precision RTD instrumentation for temperature sensing
An application note from Microchip: Precision RTD instrumentation for temperature sensing (PDF!) Precision RTD (Resistive Temperature Detector) instrumentation is key for high performance thermal management applications. This application note shows how to use a high resolution Delta-Sigma Analog-to-Digital converter, and two resistors to measure RTD resistance ratiometrically. A ±0.1°C accuracy and ±0.01°C measurement resolution can be achieved across the […]
App note: Process high-voltage input levels into a low-voltage ADC without losing much SNR
Here’s an application note from Maxim: Process high-voltage input levels into a low-voltage ADC without losing much SNR It is often difficult to find an analog-to-digital converter (ADC) that aligns with the analog input range, but also has the appropriate number of inputs, the needed size, and the correct sample speed. Especially for system designers working […]
