Differential Temperature Measurement (DTM) sub-system reference design
TIDA-01526 implements a high-precision DTM sub-system using a 24-bit, low-power, Delta-Sigma ADC.
TIDA-01526 implements a high-precision Differential Temperature Measurement (DTM) sub-system using a 24-bit, low-power, Delta-Sigma ADC. Heat and cold meter DTM subsystems typically use two 2- or 4-wire RTDs such as PT100, PT500 or PT1000 and can achieve measurement accuracy of 20 mK over a water temperature range of 3°C to 180°C. The MSP430FR6047 application MCU converts the resistance value into a temperature reading in TIDA-01526.
