摘要
CS1242是国内自行研制的最新△∑模数转换器,由于运用了电荷平衡技术,其性能可以达到24位,内部有一个极低噪声、增益可选的载波稳定仪表放大器和一个4阶△∑调制器,三线串行接口,可直接与单片机连接,非常适合测量称重传感器输出的直流毫伏信号。具有动态范围宽、电源配置灵活、体积小、功耗低、抗干扰能力强等特点,完全可以替代国外同类产品,如CS5532等。而价格不到国外同类产品的三分之一,使得该芯片成为目前用于高分辩率、低成本称重仪表的理想产品。
CS1242 is the newest △∑A/D converter produced by our nation, because of the use of the technology of charge balance, the function can reach to the 24 columns, there is a lowest -noise inside of it, the closeable gain and balanced carrier amplifier and also a 4 steps △∑ modulator, serial interface of the three thread, can join the singlechip directly, and very suitable to measure the signals of the DC millivoh of the weighting -meter, it possesses the broad mobile scale, the sensitivity of the power schemes, little volume, less assumption and high anti-interference, and it can substitute the same type of the foreign product, for example the CS5532. While the price of it only one third of the foreign product making it become the ideal the product used in the high resolution, less cost weighting instruments.
