传统的温度传感器只能提供模拟输出 ,如 :电热调节器、ＲＴＤｓ、热电偶以及后来出现的硅温度传感器。而在大多数应用中 ,这些模拟输出的温度传感器的输出端需要配置一个比较器、ＡＤＣ或放大器 ,以产生有效的信号输出。随着集成工艺的发展 ,温度传感器和数字接口已能够集成在 Traditional temperature sensors provide only analog outputs such as thermistors, RTDs, thermocouples, and later silicon temperature sensors. In most applications, however, the outputs of these analog output temperature sensors need to be configured with a comparator, ADC, or amplifier to produce a valid signal output. With the development of integrated processes, temperature sensors and digital interfaces have been integrated
