摘　　要：为了满足人们对高精度电子衡器的需求,采用了CRYSTAL公司的高精度24位串行A/D转换器CS5532进行数据采样,并利用ARM7单片机AT91SAM7X256处理采样数据。由于CS5532具有动态范围宽、功耗低、抗干扰能力强等特点,大大提高了称量速度和精度。In order to satisfy people＇s demand for high-precision electronic scale, this paper uses CRYSTAL＇s high-precision 24-bit serial A/D converter CS5532 to collect data and use ARM7 MCU AT91SAMTX256 to process data. As the CS5532 has wide dynamic range, low power consumption, strong anti-interference ability and other characteristics, it can greatly improve the weighing speed and accuracy.
