nowadays i have done my project with my accelerometer MMA7260Q for detecting position. first, i have determined trouble with the output of my sensor…as we know that the offset voltage is abaout Vdd/2, but the problem is that the voltage is unstable…it has ripple/noise…about 80mV up/down the offset…is it normal?why it can be happened?bercause it’s so influence the computation of the algorithm…an may be the result is not accurate anymore…what should i do to solve this problem?
thank’s a lot
