Additional Details

The LTC2984 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 LTC2984 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 LTC2984 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor as well as an EEPROM for storing custom coefficients and channel configuration data.

The LTC2984 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 ADC's, driven by an internal 10ppm/°C (maximum) reference.

Applications

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

    LTC2984 Demo Software
    Info:False

    The LTC2984 demo software is designed to help configure, program and run the LTC2984. It can configure the LTC2984, 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 DC2399 demo circuit.
