Accelerometer with Operational Amplifier

Description

SPICE simulation of a shock sensor amplifier (accelerometer) implemented with a LTC6081. A capacitive piezoelectric element provides a charge under physical acceleration. The charge is converted to a voltage and filtered by the high impedance of the operational amplifier. The gain is 100, the bandwidth about 2.2khz and the output generates 109mV per g of acceleration.
