Here are the typical building blocks required to measure temperature in a multi-sensor system. A thermocouple and its accompanying cold-junction diode sensor are shown, but these blocks really speak to any temperature sensor in general. At the frontline, a number of diodes and switches can be used to protect downstream circuitry from any hazards that the outside world presents. Current sources, buffers and multiplexers are then responsible for exciting and level translating each sensor that needs measurement. Afterwards, the ADC and reference, which highly dictate the accuracy of the solution, digitize the sensor signals. A processor or ASIC is then usually responsible for converting sensor voltage readings to temperature readings by using embedded look-up tables or equations. At this point, isolation may or may not be required, depending on the application. All of the blocks in blue are included in the LTC2983.
