FUNCTIONAL DESCRIPTION

The MCP960X/L0X/RL0X Thermocouple temperature

converter

consists

18-bit

Delta-Sigma

Analog-to-Digital Converter (ADC), which is used to

measure the thermocouple voltage or EMF, a digital

temperature sensor used to measure cold-junction or

ambient temperature and a processor core which is used

to compute the EMF to degree Celsius conversion using

coefficients derived from the NIST ITS-90 coefficients.

Figure 5-1 shows a block diagram of how these functions

are structured in the device.
