Application hints
Figure 3.
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
Supply
3) to implement a low-pass filter.
