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 […]

64-channel, current-input analog-to-digital converter
MichaelZ tipped us to a 64-channel, current-input analog-to-digital converter The DDC264 is a 20-bit, 64-channel, current-input analog-to-digital (A/D) converter. It combines both current-to-voltage and A/D conversion so that 64 separate low-level current output devices, such as photodiodes, can be directly connected to its inputs and digitized. For each of the 64 inputs, the DDC264 uses […]
