TOSHIBA BiCMOS Linear Integrated Circuit Silicon Monolithic
TB6066FNG
Shock Sensor IC
TB6066FNG detects an existence of external shock through the
shock sensor and output Low-level signal at 7 pin.
It has so excellent characteristic in S/N ratio that user can use
Analog signal for mechanical control systems, like servo control.
Features
• TB6066FNG 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.
• Input terminal of sensor signal is designed high impedance.
Differential input impedance = 100 MΩ (typ.)
• Three Operatinal-Amplifier is built in for design flexibility. (*Note 1)
• Sensitivity of shock detection can be adjusted by external devices.
• Small package: SSOP16-P-225-0.65B (0.65 mm pitch)
• Excellent S/N ratio: Improved 10dB compared with our TA6038FN/FNG
*Note 1: LPF (low pass filter) circuitry is not bulit in. User needs to make some filter with one
operational-amplifier to cancel the signal of resonant frequency of piezo sensor
