ADC 0809:
Analog to digital converters find huge application as an intermediate device to convert the signals from analog to digital form. These digital signals are used for further processing by the digital processors. Various sensors like temperature, pressure, force etc. convert the physical characteristics into electrical signals that are Analog in nature.


  • PCB size: 3.4*5.2cm
  • Power: 5V

Interface instruction:

  • VCC: power positive
  • GND: power negative
  • IN0-IN7: 8 channel analog data input port
  • D0-D7: 8bit data output port
  • CLK: ADC0809 clock
  • OE: output enable signal,high level is available.
  • EOC: end of conversion signal,high level is available.
  • STR: start conversion signal


  • J7: potentiometer enable control.if short J7 by jumper cap,potentiometer connect to IN3.
  • J8: control connection of VREF+ and VCC.if short J8 by jumper cap, VRET+ = VCC.if not,you can input reference voltage to VREF+.
