Arduino 24 Bit ADC Board

1. AD differential, is the voltage different (between AN+ & AN-) as the result of the switch. Refer to electric circuit, AN+ & ANconnect to one way potentiometer respectively, calculated the voltage difference.
2. If use one way A/D without differential function, then use jumper cap to connect AN- & GND, so the
individually as the one way A/D input.
3. At the bottom & interface of microcontroller, VCC & GND connect to microcontroller & ground respectively, CLK connects
to 51 microcontroller P20, D10 connects to P21, RDY connects to P22, so can control A/D switch by 51 microcontroller, if
want to use other microcontrollers needs to modify the program.
