LTC298x Digital Temperature Measurement Systems

Analog Devices Inc. LTC298x Digital Temperature Measurement Systems are used to directly digitize RTDs, thermocouples, thermistors, and diodes. The LTC298x can measure a wide variety of temperature sensors and digitally outputs with the results in °C or °F, with 0.1°C accuracy and 0.001°C resolution. Measure the temperature of virtually all standard (Type B, E, J, K, N, S, R, T) or custom thermocouples. The LTC298x automatically compensates for cold junction temperatures and linearizes the results. The device can also measure temperature with standard 2-, 3- or 4-wire RTDs, thermistors, and diodes. Analog Devices Inc. LTC2986 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.

Digital Temperature Sensors

Analog Devices Inc. Digital Temperature Sensors are part of a wide range of temperature sensing and control applications that offer many design alternatives. These solutions offer in-depth design information and circuits for building thermal sensing signal chains using the most popular thermal sensors. Usually, the first step in designing a thermal sensing and control system is to determine the temperature range that must be sensed as well as the operating environment. The next step is selecting a thermal sensor. There are four main types of thermal sensors: silicon, thermistor, RTD, and thermocouple. ADI provides either complete signal chain solutions or integrated ICs that can take the thermal transducer signal, process it, and provide either an analog or digital communication path back to the control device.
