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. Weight: 0.07 g (typ.) • 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 10d B 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

Frequently Asked Questions
What is the recommended operating voltage range?
The device operates from 2.7 to 5.5 V DC single power supply voltage.
How should I filter the signal in my design?
Since LPF circuitry is not built-in, you must use an external operational amplifier to create a low pass filter and cancel resonant frequency signals.
What does the output pin indicate when a shock occurs?
Pin 7 (CMO) provides the output; it outputs a Low-level signal ("L") when a shock is detected.
What is the differential input impedance of the sensor?
The input terminal is designed with a high impedance, specifically a differential input impedance of 100 MΩ (typ.).
