A data acquisition system for evaluation of the AD converters - art. no. 60412D

초록

In precision instrumentation system, an A/D conversion of signal conditioning has some problems, such as offset and drift errors with environmental situation. This paper suggested a development of the Multi-Channel A/D Data Acquisition System and a method of the evaluation and the temperature compensation for the A/D converters with the specific analog and digital circuit including the software. Also, with smart algorithm for better signal processing of the proposed system, hardware and software filters were designed. Software approach was adopted to obtain the stable data from A/D converter. As shown in our experimental works, the proposed system is expected to use in the industrial field where a high precision measurement is required.
