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 Block Diagram Weight: 0.07 g (typ.) 50 MΩ 15 16 50 MΩ 1 V Diff Amp 0.63 V Guard C2 C3 R1 R2 4 5 1.2 V 13 12 OP2 AMP OP3 AMP OP1 AMP 11 10 Comparator
