Application Note
Figure 1 shows the configuration of G-Force sensor amplifier.
The shock sensor is connected between the pins 1 and 16.
< How to output 0 or 1 from the pin 7 to detect whether there is a shock or not. >

Example: Detecting 5 (G)-shock using a sensor
with Qs
= 0.34 (pC/G), R1 = 10 (k), R2 = 100 (k).
Example: Setting the frequency to 20 Hz with
R1
= 10 (k).
Example: Designing the system with 200 (mV/G)
by using a sensor that Qs
= 0.34 (pC/G),
R1
= 10 (k), R2 = 100 (k).
Example: Setting the frequency to 5 kHz with
R2
= 100 (k).
