LTC2986 Multi-Sensor Temperature Measurement System

Analog Devices' LTC2986 is a 10-channel temperature monitoring system that can measure a wide variety of temperature sensors and digitally output the results in °C or °F with 0.1°C accuracy and 0.001°C resolution. The LTC2986 can measure the temperature of virtually all standard (Type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate for cold junction temperatures, and linearize the results. The device can also measure temperature with standard 2-, 3- or 4-wire RTDs, thermistors, and diodes. The LTC2986 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor. These devices are 10-channel software and pin compatible versions of the 20-channel LTC2983/LTC2984. Additional features include special modes that enable easy protection in universal multi-sensor applications, custom tables for generic ADC readings, and direct temperature readout from active analog temperature sensors. The LTC2986-1 is the EEPROM version of the LTC2986. The LTC2986 is ideal for thermocouple, RTD, and thermistor measurements applications.
