Beschreibung
- REFD5032, Reference design for the Thermocouples are used in a wide range of temperature-sensing applications. To utilize all the new thermocouple capabilities, high-resolution thermocouple temperature-measurement systems are required. A low-noise, 24-bit, delta-sigma analog-to-digital converter (ADC) with the ability to resolve very small voltages perfectly fits this task. When a data acquisition system (DAS) uses the evaluation kit for a 24-bit ADC, thermocouple temperature measurements can be made across that wide temperature range. When the thermocouple, platinum resistance temperature detector (PRTD) and ADC are integrated in a circuit, they enable a high-performance temperature-measurement system. The ADC-based DAS can also be designed to operate at very reasonable cost and with low power consumption, making it ideal for portable sensing applications
