LTC2983CLX#PBF

The LTC2983CLX#PBF is a multi-sensor high accuracy digital temperature Measurement System with 0.1°C accuracy and 0.001°C resolution. The LTC2983 can measure the temperature of virtually all standard (type B, E, J, K, N, S, R and 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. It has 20 reconfigurable analogue inputs enabling many sensor connections and configuration options. The LTC2983 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor. It allows direct interfacing to ground referenced sensors without the need for level shifters, negative supply voltages or external amplifiers. All signals are buffered and simultaneously digitized with 3 high accuracy, 24-bit Δ? ADC's, driven by an internal 10ppm/°C (maximum) reference.
