摘要
CS5524是一种理想的4通道增益可编程的A/D转换器,具有功耗低、精度高、抗干扰能力强和测量量程范围大等优点,被广泛应用于小角度测量、精密称重或微弱信号采样等领域。为此,研究了其与ARM的SPI口交换数据,并通过实例说明其在植物蒸腾测定仪上的应用。
The 24 - bit CS5524 is an ideal 4 channel A/D converter which contains a gain programmable amplifier. It can be widely used in such fields as surveys of small angle, precision weighing and samples of faint signal because it has advantages of low power consumption, high precision, strong anti -jamming ability and wide measurement adjusting range. This paper tries to communicate it with ARM via SPI and gives the example of its application in plant stem sap flow measuring instrument.
