LTC2986CLX#PBF

LINEAR TECHNOLOGY  LTC2986CLX#PBF  温度传感器芯片, 数字式, ± 0.1°C, 0 °C, 70 °C, LQFP, 48 引脚 新

The is a 10 channel multi sensor high accuracy digital temperature measurement system 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 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 and linearize the 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 versions of 20 channel LTC2983. 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 applications.
