概述MAX31725/MAX31726温度传感器提供高精度温度测量,以及过热报警/中断/关断输出。器件利用高分辨率Σ-Δ模/数转换器(ADC)将温度测量值转换为数字输出,在-40℃至+105℃范围内保持±0.5℃精度。通过I2C兼容2线串口通信。I2C串口支持标准写字节、读字节、发送字节和接收字节命令,以读取温度数据并配置过热关断开漏输出。MAX31725具有三个地址选择引脚,提供32个总线地址。MAX31726具有两个地址选择引脚,提供16个总线地址,并带有1个/RESET输入。传感器采用2.5V~3.7V供电,电源电流低至
General Description The MAX31725 / MAX31726 temperature sensors provide high-precision temperature measurement and overheat alarm / interrupt / shutdown outputs. The device utilizes a high-resolution Σ-Δ analog-to-digital converter (ADC) to convert temperature measurements to digital output with ± 0.5 ° C accuracy over the -40 ° C to + 105 ° C temperature range. I2C compatible 2-wire serial communication. I2C serial port supports standard write byte, read byte, send byte and receive byte commands to read temperature data and configure overheat shutdown open-drain output. The MAX31725 has three address select pins that provide 32 bus addresses. The MAX31726 has two address select pins that provide 16 bus addresses with one / RESET input. 2.5V ~ 3.7V power supply sensor, the power supply current as low as
