illustrate

LM95172EWG是一个集成的数字输出温度传感器与一个串行外设接口（SPI）和MICROWIRE™兼容的接口在一个10针Cerpack高温陶瓷封装。 它具有一个非常线性的sigma - delta模拟数字转换器（ADC），精度高，快速的转换率，以及极低的输出噪声。 随着工作温度低至-40 ° C和优化精度从120 ° C到200 ° C，它是用于高温应用的理想选择。

超温报警输出（^ OVERTEMP）说，当管芯温度超过编程targetT HIGH限制。 用户设定的TLOW限制创建一个触发点是当环境温度接近的温度稳定的滞后。

LM95172EWG可以进行编程，从13位（0.0625 ° C每LSB），16位（0.0078125 ° C每LSB）的决议。 在35毫秒，速度最快的转换时间，LM95172EWG温度设定在13位分辨率输出。 该决议可能会被更改为14 - ，15 - 或16位。 当在13 - ，14 - 或15位分辨率模式下，温度在16位的最低有效位的寄存器，每次转换完成后切换。 此位可被监控，以确认转换完成。

的串行I / O（SI / O），输出的高抗干扰性，使得 LM95172EWG 在富有挑战性的电磁环境中使用的理想选择。
