Fig.1 The Composition of G-Force Sense Amplifier
Fig.1 is the composition of G-force sense amplifier.
The shock sensor is connected between 1 and 2 terminal. (Please connect the positive polarity side
to 1 terminal.)
The setting of sensitivity is adjusted by external resistors of R1 & R2. Please refer to below figure
(fig.2) about setting value. For instance, when the signal from sensor (1 terminal input signal) is
5mV, the standard setting for detection is following :
RI--15k1 R2 = 500m
Besides, the liner high pass filter is composed by C1 & R1, and the secondary LPF is composed by
C1 & C2. Its cut-off frequency is defined as:

TOSHIBA TA8563FN
CAUTION IN USING THE TA8563FN
The treatment of connection from the shock sensor to signal input terminal (1 terminal) :
1 terminal of the TA8563FN is high-impedance input terminal. Therfore, please pay attetion not to
occur the leak current from other terminals.
If the leak current occured to 1 terminal (Particularly at soldering on PC substrate), there is
possibility to cause the problem of operation.
Due to avoid this problem, it's recommended to circule the signal line between the shock sensor
and 1 terminal by 2 terminal line, same voltage as 1 terminal.
(Please refer to the below application circuit.)
. The shock sensor:
Please confirm the characteristic of the using shock sensor sufficiently.
. Vcc, GND:
Please connected the capacitor between VCC and GND closely to the TA8563FN.
