DAC线路在数据采集应用中的研究

Research on DAC Circuit in Data Acqursition Application

本文就DAC线路在数据采集应用中出现的上电复位瞬间状态不确定,产生饱和输出,以及DAC线路在应用中失调误差、增益误差和非线性误差的调整进行了介绍,提出了相应的解决方法。

When power on resetting,the input of DAC circuit is uncertain and it will cause a full scale ontput. Moreover in DAC application,the offset error,gain error and non-linear error are offen taken place. This paper introduces a relevant method to overcome above phenomena.
