TA6009FNG

TA6009FN/FNG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA6009FN,TA6009FNG Shock Sensor IC (1 ch version) TA6009FN/FNG detects an existence of external shock through the shock sensor and output. Features • • TA6009FN/FNG 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. TA6009FN/FNG incorporates 1-ch shock detecting circuitry. Input terminal of sensor signal is designed high impedance. Differential input impedance = 100 MΩ (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.
