DS1624在测量温度时使用了独有的在线温度测量技术。它通过在一个由对温度高度敏感的振荡器决定的计数周期内对温度低敏感的振荡器时钟脉冲的计数值的计算来测量温度。DS1624在计数器中预置了一个初值,它相当于－55℃。如果计数周期结束之前计数器达到0，已预置了此初值的温度寄存器中的数字就会增加，从而表明温度高于－55℃。 -DS1624 temperature in the measurement of the use of a unique online temperature measurement technology. By temperature in a highly sensitive decision oscillator cycle count on the low-temperature-sensitive oscillator clock pulse of the numerical calculations to measure the temperature. Counters in the DS1624 in a preset initial value, which is equivalent to-55 ℃. If the count before the end of the cycle counter reaches 0, this initial value has been preset temperature register will increase the number in order to show that the temperature is higher than-55 ℃.
