具有引脚可编程总线地址的高精度远程和本地温度传感器

TMP461 器件是一款高精度、低功耗远程温度传感器监控器，内置有一个本地温度传感器。这类远程温度传感器通常采用低成本分立式 NPN 或 PNP 晶体管，或者基板热晶体管或二极管，这些器件都是微处理器、微控制器或现场可编程门阵列 (FPGA) 的组成部件。本地和远程传感器均用 12 位数字编码表示温度，分辨率为 0.0625°C。此两线制串口接受 SMBus 通信协议，以及多达 9 个不同的引脚可编程地址。 该 器件 将诸如串联电阻抵消、可编程非理想性因子（η 因子）、可编程偏移、可编程温度限制和可编程数字滤波器等高级特性完美结合，提供了一套准确度和抗扰度更高且稳健耐用的温度监控解决方案。 T • 远程二极管温度传感器精度：±0.75°C\n• 本地温度传感器精度：±1°C\n• 本地和远程通道的分辨率：0.0625°C\n• 电源和逻辑电压范围：1.7V 至 3.6V\n• 35µA 工作电流 (1SPS)， 3µA 关断电流\n• 串联电阻抵消\n• η 因子和偏移校正\n• 可编程数字滤波器\n• 二极管故障检测\n• 两线制和 SMBus串行接口与引脚可编程的地址兼容\n• 10 引脚超薄型四方扁平无引线 (WQFN) 封装;
