摘要：
An integrated analog chip tester has been designed. Since we need to test the analog voltage of analog devices, a kernel architecture based on Single Chip Computer(MCU) and AD converter has been designed. In order to solve the possible blight to tester caused by the damaged chips. This paper presents a technology for isolating inside and outside bus, a technology for double power supplies and a technology for power supply protection. The whole design idea of the tester is introduced in detail. AD converter circuit, DA converter circuit, Op amp testing circuit, CW3524 testing circuit and LCD interface circuit have been designed. The procedure of software design is presented, and the primary software modules are explained in detail. Experiment showpiece has been developed. The results of experiments verify the correctness of the design.
