Universal Temperature Sensor Includes EEPROM

Universal Temperature Sensor Includes EEPROM
Linear Technology Corp.

With an eye on modular and custom systems, the LTC2984 digital temperature sensor IC integrates EEPROM to store user configuration data and custom sensor coefficients. This addition eliminates any IC or sensor programming by a host processor and enables the use of self-contained temperature sensing boards or modules. The LTC2984 includes all of the features found on the LTC2983 and is pin compatible. It provides a multiplexed high precision interface to virtually any sensor and measures absolute microvolt-level signals from thermocouples and ratiometric resistance measurements from RTDs and thermistors, linearizes the results and outputs them in °C or °F. Up to twenty analog inputs are available and digitized measurements can be output in Centigrade or Fahrenheit. Additionally, the LTC2984 interfaces with a wide variety of temperature sensors, including type B, E, J, K, N, S, R, T thermocouples, 2-, 3-, or 4-wire RTDs, 2.25kΩ to 30kΩ thermistors and temperature sensing diodes. Available in commercial and industrial versions supporting operating temperature ranges from 0°C to 70°C and -40°C to 85°C, respectively, the LTC2984 comes in a 48-lead, 7mm x 7mm LQFP. Pricing starts at $21.43 each/1,000. For a datasheet, visit http://www.linear.com/product/LTC2984
