Thermocouple Measurement using 16/24 bit AD7792/AD7793 sigma delta ADCs. These ADCs are complete with an analog front end PGA that allows for direct connection to the ADC. It also includes internal current sources required for the TC compensation measurement providing a totally integrated solution.
2 Wire RTD measurement using the AD7781, 20 bit Sigma Delta ADC. This solution is ratiometric therefore any drift in the current source is canceled out as the current source is also used to drive the reference input resistor.
3 wire 16/24 bit RTD measurement. The AD7792/AD7793 are 16/24 bit Sigma Delta complete with an analog front end PGA that allows for direct connection to the ADC. It also includes internal current sources required for the RTD measurement providing a totally integrated solution.
