LTC2983HLX#PBF DESCRIPTION

The LTC®2983 measures a wide variety of temperaturesensors and digitally outputs the result, in °C or °F, with0.1°C accuracy and 0.001°C resolution. The LTC2983 canmeasure the temperature of virtually all standard (type B,E, J, K, N, S, R, T) or custom thermocouples, automaticallycompensate for cold junction temperatures and linearizethe results. The device can also measure temperature withstandard 2-, 3- or 4-wire RTDs, thermistors and diodes. Ithas 20 reconfigurable analog inputs enabling many sen-sor connections and configuration options. The LTC2983includes excitation current sources and fault detectioncircuitry appropriate for each type of temperature sensor.The LTC2983 allows direct interfacing to ground referencedsensors without the need for level shifters, negative supplyvoltages, or external amplifiers. All signals are buffered andsimultaneously digitized with three high accuracy, 24-bit ∆∑ADCs, driven by an internal 15ppm/°C (maximum) reference.
