TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA6042FNG
Shock sensor IC for signal processing
TA6042FNG performs the signal processing in response to the
amplification signal of a shock sensor.
Features
TA6042FNG is operated under 4.5 ~ 5.5 V DC single power
supply voltage.
User can make notch-filter circuit with OP-AMP2 and
external element, and adjust gain by changing R1/R2 Ratio.
To change the g-force sensing level, user can adjust gain by
changing R7/R8 ratio.
The Window comparator has a hysteresis which width is
about 150mV.
Small package: SSOP10-P-0.65A (0.65 mm pitch)

Note: The IC may be destroyed due to short circuit between adjacent pins, incorrect orientation of device's mounting,
connecting positive and negative power supply pins wrong way round, air contamination fault, or fault by
improper grounding.
Please consider the voltage-drop caused by OP-AMP3 input current and feedback resistance (R8), and
examine the value of the feedback resistance.
We will recommend 500k or less as a value of the feedback resistance.
TA6042FNG is Pd free product..
