Figure 1 The Composition of G-Force Sense Amplifier

Figure 1 is the composition of G-Force sense amplifier.

The shock sensor is connected between 1 and 2 terminal.

When G-force Sensor (sensor sensibility = s (mV/G)) is used to detect external shock of g (G), the external

parts are determined as following.

(gain setting) * 10 PIN → GND

500/(s × g) = G1

G1/10 = G (OP-AMP)

(HPF setting)

fc = 1/(2 π × R1 × C1)

(LPF setting)

fc = 1/(2 π × R2 × C2)
