摘要
近年来隔离放大器的指标在不断提高,性能也在不断提升,应用范围越来越广,伴随着隔离放大器的发展,对用来考核放大器指标的测试技术也提出了相应的要求。论文针对常用的隔离运算放大器AD204,结合测试标准,研究其测试方法、设计了测试电路,提出了提高测试参数准确性的几项措施,实现了对AD204重要参数指标的测试。
In recent years,the technology of isolation amplifier continues to improve,the performance is also rising,more and more isolation amplifiers are applied to the instrument,communication and other fields.With the development of the isolated amplifier,it also sets a higher request to the test technology of amplifier index.Combined with the test standard,this paper studies the testing method,designs the test circuit,raises several measures to improve the accuracy of the test parameters.
