| TA6009FM TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA6009FM Shock Sensor IC (1 ch version) TA6009FM detects an existence of external shock through the shock sensor and output. Features * * TA6009FM operates from 2.7 to 5.5 V DC single power supply voltage. Signal from the shock sensor is amplified according to setting gain, and is detected through the internal window comparator. TA6009FM incorporates 1-ch shock detecting circuitry. Input terminal of sensor signal is designed high impedance. Differential input impedance = 100 M (typ.) * * * LPF (Low Pass Filter) circuitry is incorporated. Cut-off frequency of LPF = 7 kHz Sensitivity of shock detection can be adjusted by external devices.
