LTC2986CLX-1#PBF

The LTC2986CLX-1#PBF is a 10-channel multi sensor high accuracy digital temperature measurement system with EEPROM in 48 pin LQFP package. It measures wide variety of temperature sensors and digitally outputs result in °C or °F with 0.1°C accuracy and 0.001°C resolution. The LTC2986-1 can measure temperature of virtually all standard (type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate for cold junction temperatures & linearize results. The device can also measure temperature with standard 2, 3 or 4-wire RTDs, thermistors and diodes. It is 10 channel software and pin compatible version of 20 channel 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 analogue temperature sensors. It is used for direct thermocouple measurements, direct RTD measurements, direct thermistor measurements & custom sensor applic
