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 Ry & 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 : Ry =15kQ, R2=500k0 Besides, the liner high pass filter is composed by C1 & Ry, and the secondary LPF is composed by C1 & Cp.

CAUTION IN USING THE TA8563FN 1. 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.) 2. The shock sensor : Please confirm the characteristic of the using shock sensor sufficiently. 3. Vcc, GND: Please connected the capacitor between Vcc and GND closely to the TA8563FN.
