Recently i got samples of ADW22035 acceleration sensors. When i tried to check those sensor i got only around 200 mv flucuation, i gentely tapper the sensor to get vibration signal. As per datasheet it has 18 g range but i couldn't get(1.8 V) that much voltage output during tesing. when i give Vs=5 volt to self test pin, output shows around 90mv change. So basically sensor is not damaged and it works fine,
Can anybody suggest what could be the wrong? why am i not gettting vibration signal when i tapper the sensor mounted PCB?
Thanks in advance
