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
Weight: 0.07 g (typ.)
