随着计算机技术的飞速发展,用于各种生产过程的数据采集系统和自动检测仪表不断出现。而模数转换则是其中的一个重要环节。对于工业生产来说,环境往往是很恶劣的,因此抗干扰问题就是一个急待要解决的关键问题。双积分A/D转换器的特点是具有很强的抗工频干扰能力。 With the rapid development of computer technology, data acquisition systems and automatic detection instruments for various production processes are constantly emerging. The analog-to-digital conversion is one of the important links. For industrial production, the environment is often very harsh, so the anti-interference problem is an urgent problem to be solved. Double integration A / D converter is characterized by strong anti-frequency interference.
