Linear Technology LTC2983CLX#PBF

Description
The LTC2983 is a high-accuracy, multi-sensor temperature measurement system that directly digitizes RTDs, thermocouples, thermistors, and diodes. It operates on a single 2.85V to 5.25V supply and provides results in °C or °F with 0.1°C accuracy and 0.001°C resolution.
The LTC2983 features 20 flexible inputs, allowing for interchangeable sensors. It includes automatic thermocouple cold junction compensation and built-in standard and user-programmable coefficients for thermocouples, RTDs, and thermistors. The device supports configurable 2-, 3-, or 4-wire RTD configurations and can measure negative thermocouple voltages.
