5.1 Applications schematic
Figure 8 on page 13 shows the schematic of a typical application for the STA333ML.
Concerning the power supplies, take care when designing the PCB layout. In particular, the
3.3-Ω resistors on the digital supplies (VDD_DIG) must be placed as close as possible to
the device. This helps to prevent parasitic oscillation in the digital part of the device due to
the inductive tracks of the PCB. The same rule applies for all the decoupling capacitors in
order to limit any spikes on the supply pins.
