11.2 Layout Example
THS3491
SBOS875 – AUGUST 2017
THS3491RGT thermal pad
directly on top of blind vias
Rout pad closer to
the device output
Blind Vias to GND to help with
heat dissipation out of the board
Power Connection with Vias
to the internal power plane
Figure 17. RGT Package Layout Example
GND trace cut-out underneath the device inputs
and output from PCB second layer to the fourth
layer in-order to reduce PCB parasitic capacitance
