集成温度传感器是利用集成电路工艺开发出的一种固态温度敏感器件,由于将基准电压、线性放大、温度补偿等电路集成在同一芯片上,因而具有输出特性好、灵敏度和测量精度高、外围接口简单、功耗低、线性优良、稳定性好、体小量轻等等特征,并得到迅速推广应用。就集成温度传感器的输出方式而言,国内市场上有电流型、电压型、电容型、频率型等多种,但其用途广泛的产品却是AD590电流 Integrated temperature sensor is the use of integrated circuit technology developed a solid-state temperature-sensitive devices, as the reference voltage, linear amplification, temperature compensation circuit integrated in the same chip, which has good output characteristics, sensitivity and measurement accuracy, peripheral interfaces Simple, low power consumption, excellent linearity, good stability, small body weight and so on, and has been rapidly popularized and applied. Integrated temperature sensor output mode, the current market there are current type, voltage type, capacitance type, frequency type and other, but its wide range of products is AD590 current
