Multichannel Remote/Local Temperature Sensors

General Description The MAX1668/MAX1805/MAX1989 are precise multichannel digital thermometers that report the temperature of all remote sensors and their own packages. The remote sensors are diode-connected transistors—typically low-cost, easily mounted 2N3904 NPN types—that replace conventional

多通道远端/本地温度传感器

MAX1668/MAX1805/MAX1989均为高精度多通道数字温度计，可报告所有远程传感器及其自身封装的温度。远程传感器为二极管连接式晶体管（通常为低成本、易于安装的2N3904 NPN型），可取代传统的热敏电阻或热电偶。对于多个晶体管制造商来说，远程精度为±3°C，无需校准。远程通道还可以测量其他包含片上二极管连接式晶体管的IC（例如微处理器）的芯片温度。\n\n 2线串行接口接受标准系统管理总线(SMBus™)写入字节、读取字节、发送字节和接收字节命令，以对报警阈值进行编程并读取温度数据。数据格式为7位加符号，每一位对应1°C，采用二进制补码格式。\n\n MAX1 • 多通道\n• 4个远程通道，1个本地通道(MAX1668/MAX1989)\n\n• 2个远程通道，1个本地通道(MAX1805)\n\n\n\n\n• 无需校准\n\n• SMBus 2线串行接口\n\n• 可编程欠温/过温警报\n\n• 支持SMBus警报响应\n\n• 精度\n• ±2°C（+60°C至+100°C，本地）\n\n• ±3°C（-40°C至+125°C，本地）\n\n• ±3°C（+60°C至+100°C，远程）\n\n\n\n\n• 待机电源电流：3µA（典型值）\n\n• 电源电流：700µA（最大值）\n\n• 小型16引脚QSOP/TSSOP封装;
