LTC2983ILX#PBF

LTC2983 is a multi-sensor high accuracy digital temperature measurement system. It 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. This 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. It 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. It is widely used in application such as direct thermocouple measurements, direct RTD measurements, direct thermistor measurements, custom sensor applications etc.
