The board function description:

  • VCC: The power supply side
  • GND: Ground;
  • DRDY: Logic output;
  • DOUT: Serial data output;
  • DIN: Serial data input;
  • SCK: The serial clock;
  • CS: Chip Selection;
  • RST: Reset terminal;
  • AIN1+: Sampling points of the anode;
  • AIN1-: Sampling points of the negative; //Get rid of R3 can make differential input
  • AIN2+: Sampling points of the anode;
  • AIN2-: Sampling points of the negative; // Get rid of R6 can make differential input
  • Remove the R2,R5 can improve the input impedance.

Applications

  • Intended for the measurement of wide, dynamic range, low frequency signals, such as those in industrial-control or process-control applications.
