The joint circuit between MMA1260D and ATmega8L

Acceleration sensor for MMA1260D collects the data of mobile acceleration. And it goes through the port of PC0 of ATmega8L(ADC0) to ATmega8L. It forms a direct ratio of the output voltage and the acceleration of MMA1260D's acceleration sensor. For measuring the output voltage of acceleration sensor,usually we use microcontroller with A/D. For specific connection,see chart. There is a filter between VOUT and the RC of A/DIN's pin.It is used for reducing the noise of the clock. There is no strong electric current between acceleration sensor and microcontroller.The 0.1μF capacitance between power-supply and ground is the decoupling capacitance.
