LTC2983ILX#PBF

LINEAR TECHNOLOGY LTC2983ILX#PBF Temperature Sensor IC, Digital, ± 0.1℃, -265℃, 1800℃, LQFP, 48Pins

The is a Multi-Sensor High Accuracy Digital Temperature Measurement System measures a wide variety of temperature sensors and digitally outputs the result, in °C or °F, with 0.1°C accuracy and 0.001°C resolution. The device 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 device includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor. The LTC2983 allows direct interfacing to ground referenced sensors without the need for level shifters, negative supply voltages or external amplifiers.
