... Sleep mode, self test and power down The LY3100ALH enables advanced power-saving features thanks to the availability of three different operating modes. When the device is set in a Sleep mode configuration, the reading chain is completely turned off, resulting in low power consumption. In this condition the device turn-on time is significantly reduced, allowing simple external power cycling ...

... ANGULAR RATE Power supply decoupling capacitors should be placed in combination with an LDO regulator (common design practice). The LY3100ALH IC includes a PLL (phase-locked loop) circuit to synchronize driving and sensing interfaces. Capacitors and resistors must be added at VCONT pin 3 (as shown in Figure 3) to implement a low-pass filter. ...
