ADT7408: ±2°C精度、12位数字温度传感器
ADT7408是符合JEDEC移动平台存储器模块标准JC-42.4的第一款数字温度传感器。 该器件内置一个带隙温度传感器和一个12位ADC，用来监控温度并进行数字转换，分辨率为0.0625°C。内置一个开漏Event#输出，当监控温度超过可编程临界限值或者温度高于或低于警报窗口时，该输出有效。 该引脚能够以比较器模式或中断模式工作。 同时配有三个从机地址引脚，通过它们可以在用于监控各种元件和子系统温度的系统中最多使用8个ADT7408。ADT7408的额定工作电压范围为3.0 V至3.6 V，工作电压为3.3 V时，平均电源电流的典型值低于240 μA。 ADT7408提供关断模式来实现器件断电，关断电流典型值为3 μA。 ADT7408的额定工作温度范围为-20°C至+125°C。 ADT7408采用无铅8引脚LFCSP 3mm x 3mm (JEDEC MO- 229 VEED-4)封装。
The ADT7408 is the first digital temperature sensor that complies with JEDEC standard JC-42.4 for Mobile Platform Memory Module. The ADT7408 contains a band gap temperature sensor and 12-bit ADC to monitor and digitize the temperature to a resolution of 0.0625°C.There is an open-drain Event# output that is active when the monitoring temperature exceeds a critical programmable limit or the temperature falls above or below an alarm window. This pin can operate in either comparator or interrupt mode. There are three slave-device address pins that allows up to eight ADT7408s to be used in a system that monitors temperature of various components and subsystems.The ADT7408 is specified for operation at supply voltages from 3.0 V to 3.6 V. Operating at 3.3 V, the average supply current is less than typically 240μA. The ADT7408 offers a shutdown mode that powers down the device and gives a shutdown current of typically 3 μA. The ADT7408 is rated for operation over the –20°C to +125°C temperature range. The ADT7408 is available in lead-free 8-lead LFCSP 3mm x 3mm (JEDEC MO- 229 VEED-4) package
