| Abstract: | This paper introduces the application of single chip microprocessor in the operational amplifier (OP) measuring system. As a,result of adopting single chip microprocessor, the measuring system can be an intelligent system and has a great flexiibility. It can test the main parameters (the offset voltage, offest current, common mode rejection ratio and open loop gain etc.) of IC operational amplifier automatically and can be also used to test single OP, twin OP and four OP. The architecture of the whole system is simple, convenient to test and the test is rapid. |
