Analog Devices / Maxim Integrated MAX31629 I2C 数字温度计 & 实时时钟（RTC）

MaximMAX31629 I2C 数字温度计 & 实时时钟(RTC)在一个 8 引脚 TDFN 小外形封装（SOP）内集成实时时钟和温度监控器的主要功能。与器件的通信是通过一个 I2C 接口。该器件具有宽幅的电源范围和最低的供电要求，在电池供电应用中可以实现精确的时间/温度测量。数字温度计提供 9 位到 12 位温度读数，用以指示器件的温度。不需要另外的元件；该器件是真正的“温度到数字”转换器。

特性

  • Measures temperatures from -55°C to +125°C or -67°F to +257°F
  • Counts seconds, minutes, hours, day, day of the week, month, day of the month, and year
  • Leap-year compensation through the year 2100
  • ±2.0°C thermometer accuracy
  • User programmable thermometer resolution to 9, 10, 11, or 12 Bits
  • User definable thermostatic and time alarm settings
  • Dedicated open-drain alarm output
  • 32 bytes of SRAM for general data storage
  • Data is read from/written to through an I2C serial interface (open-drain I/O lines)
  • 2.2V to 5.5V wide power supply range
  • 8-Pin TDFN package

应用

  • Data loggers and any thermally sensitive systems
  • Industrial equipment
  • Networking equipment
  • Office equipment
