Abstract

Abstract

In view of problem that self-carried AD conversion module of DSP chip TMS320F2812 cannot meet requirement of collecting parameters of current and voltage synchronously, a data collection system with multi-channel based on AD7606 was designed. Design of voltage/current input circuit, input filtering circuit, interface circuit between AD7606 and TMS320F2812, AD conversion program of the system were introduced in details. Test result shows that AD conversion result by using AD7606 has high precision and small error compared with AD conversion result by using self-carried AD conversion module of TMS320F2812, and it is suitable for AD conversion circuit with high precision.
