摘要
The circuit of the signal acquisition module was designed and accomplished based on 24 high-precision Delta-Sigma type serial A/D conversion chip ADS1258, employed Xilinx xc3s2000 FPGA as acquisition controller embedded in the chassis of NI Compact-RIO, and host-programmed by Labview. The module achieved 16 Single-Ended input-channels with up to 23.7kHz (maximum) analog signal acquisition sampling rate. In addition to taking full advantage of ADS1258 on-chip function, the circuit contains single-ended-to-differential part, reference power, voltage isolation and other modules to ensure the accuracy and stability of the data acquisition.
