Features

/Gb7/G20TA6038FN operates from 2.7 to 5.5 V DC single power supply voltage. /Gb7/G20Signal from the shock sensor is amplified according to setting gain, and is detected through the internal window comparator. /Gb7/G20TA6038FN incorporates 1-ch shock detecting circuitry. /Gb7/G20Input terminal of sensor signal is designed high impedance. Differential input impedance = 100 M Ω (typ.) /Gb7/G20LPF (low pass filter) circuitry is incorporated. Cut-off frequency of LPF = 7 kHz /Gb7/G20Sensitivity of shock detection can be adjusted by external devices. /Gb7/G20Small package SSOP10-P-0.65A (0.65 mm pitch) Block Diagram Pin Connection (top view) Weight: 0.04 g (typ.)
