Ground connections
The ST7580 presents analog and digital ground connections. In particular, VSS is the power
ground, VSSA is the analog ground, while GND pins refer to digital ground.
It is recommended to provide external connections between the ground pins as follows:
●
GND pins 6, 14, 33, and 45 are connected together;
●
VSSA pins 15 and 35 are connected to the exposed pad;
●
VSS is also connected to the exposed pad;
●
Connection between VSSA and GND is provided through a ferrite bead.
