The LTC2983 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 LTC2983 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. It has 20 reconfigurable analog 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.

The LTC2983 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 three high accuracy, 24-bit ΔΣ ADCs, driven by an internal 10ppm/°C (maximum) reference.

Applications

  • Direct Thermocouple Measurements
  • Direct RTD Measurements
  • Direct Thermistor Measurements
  • Custom Sensor Applications

LTC2983 Demo Software
Info:False

The LTC2983 demo software is designed to help configure, program and run the LTC2983. It can configure the LTC2983, save the configuration, check for configuration errors, run the conversion results into a text file, and create Linduino-ready C code based on the configuration. The software can be used by itself, or used in conjunction with the DC2209 demo circuit.

Product Detail

The DC2296 is the starter kit for demonstrating the performance and ease of use of the LTC2983, which is a complete temperature measurement system on a chip. This kit includes the DC2209 (main demo circuit containing the LTC2983) and the DC2210 (a simple experiment circuit allowing bread boarding). In addition to the starter demonstration kit, sensor specific demonstration boards highlighting the performance of RTDs, thermistors, or thermocouples are also available.
