@@@@Signal generator circuit although it is the most widely used the most basic electronic devices, its each index requirements and performance to the electronic system stability and precision is very important, the traditional analog signal source in the output frequency, waveform amplitude, phase and stability indices such as already difficult to meet the application requirements. They have according to the digital frequency synthesis(DDS)technology developed LM47112 three-phase sine wave circuit, without the high cost, process complex linear circuit and the present popular devices such as PAG, realize the device of high precision and high stability. The paper introduces the detail of our design idea and the selected device experimental analysis and calculation, and at the same time, it gives the circuit test results and special circuit, in order to meet the requirements of different users.
