ＤＳ１８２０数字温度计的应用ＤＳ１８２０数字温度计突破系统的“传感器加Ａ／Ｄ变换”的温度采集模式，直接提供９位温度读数。它通过在门开通期间对低温度系数振荡器经历的时钟周期个数计数来测量温度，而门开通期由高温度系数振荡器决定；数据线采用串行“单线总线”... DS1820 digital thermometer applications DS1820 digital thermometer breakthrough system’s “sensor plus A / D conversion” temperature acquisition mode, providing direct 9-bit temperature readings. It measures the temperature by counting the number of clock cycles experienced by a low temperature coefficient oscillator during the gate-on period, which is determined by the oscillator of the high temperature coefficient; the data line uses a serial “single-wire bus” ...
