TA6039FN
Shock Sensor IC
TA6039FN detects an existence of external shock through the
shock sensor and output.
Compared with TA6009FN, S/N ratio is improved by 8dB.
It is suitable for applications which require low-noise operation.
Features
· TA6039FN 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.
· TA6039FN 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.
· Small package
SSOP10-P-0.65A (0.65 mm pitch)
Weight: 0.04 g (typ.)
