Note 5)
Notes: 1. The acceleration unit "g" means 9.8 m/s
2. VDD typical value of each part number when nothing is specified.
3. Maximum error from linear output that connects +2 g and –2 g output.
4. "C1" is a ceramic capacitor installed between the VDD and GND terminals. "C2" is a ceramic capacitor installed between the Vout (X) and Ext-Cap (X) terminals.
"C3" is a ceramic capacitor installed between the Vout (Y) and Ext-Cap (Y) terminals.
5. The frequency characteristics can be changed depending on the C2 and C3 capacitance value. Please refer to "Recommended circuit diagram" on the following
page. Note that the maximum frequency response is 60 Hz.
