Application hints
Figure 12. L3G4200D electrical connections and external component values
Power supply decoupling capacitors (100 nF ceramic or polyester +10 µF) should be placed
as near as possible to the device (common design practice).
If Vdd and Vdd_IO are not connected together, power supply decoupling capacitors
(100 nF and 10 µF between Vdd and common ground, 100 nF between Vdd_IO and
common ground) should be placed as near as possible to the device (common design
practice).
The L3G4200D IC includes a PLL (phase locked loop) circuit to synchronize driving and
sensing interfaces. Capacitors and resistors must be added at the PLLFILT pin (as shown in
