The LTC2986 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 LTC2986 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 LTC2986 includes excitation current sources and fault detection circuitry appropriate for each type of temperature sensor.

The LTC2986/LTC2986-1 are 10-channel software and pin-compatible versions of the 20-channel LTC2983/LTC2984. Additional features include special modes that enable easy protection in universal multi-sensor applications, custom tables for generic ADC readings, and direct temperature readout from active analog temperature sensors. The LTC2986-1 is the EEPROM version of the LTC2986.

Applications

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

LTC2986 Demo Software
Info:False

The LTC2986 demo software is designed to help configure, program and run the LTC2986. It can configure the LTC2986, 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 DC2618 demo circuit.
