In order to achieve the requirements of high-precision and network transmission in data acquisition card
we propose a design of high-precision data acquisition card based on LAN.In terms of hardware
it uses ARM as the host CPU and expands the LAN interface chip.It achieved the features of LAN interface of data acquisition card and high-precision of data acquisition card by high-precision 16-bit AD converter AD976;by using FPGA internal logic to control ADC for sampling and the channels for switc...
