LTC2984 Datasheet Multi-sensor High ACcuracy Digital Temperature Measurement System

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC2984.

General Description

nn Directly Digitizes 2-, 3-, or 4-Wire RTDs, Thermocouples, Thermistors, and Diodes nn On-Chip EEPROM Stores Channel Configuration Data and Custom Coefficients nn Single 2.85V to 5.25V Supply nn 20 Flexible Inputs Allow Interchanging Sensors nn Automatic Thermocouple Cold Junction pensation nn Built-In Standard and User-Programmable Coefficients for Thermocouples, RTDs and Thermistors nn Measures Negative Thermocouple Voltages nn Automatic Burn Out, Short-Circuit and Fault Detection nn Buffered Inputs Allow External Protection nn Simultaneous 50Hz/60Hz Rejection nn Includes 15ppm/°C (Max) Reference (I-Grade) APPLICATIONS nn Direct Thermocouple Measurements nn Direct RTD Measurements nn Direct Thermistor Measurements nn Custom Sensor Applications The LTC®2984 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 pensate 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.
