Layout Notes
12.1.3.1 Device, Copper, and Component Layout
Primarily, the goal of the PCB design is to minimize the thermal impedance in the path to those cooler structures. These tips should be
followed to achieve that goal:
• Avoid placing other heat producing components or structures near the amplifier (including above or below in the end equipment).
• If possible, use a higher layer count PCB to provide more heat sinking capability for the TAS5805M device and to prevent traces and
copper signal and power planes from breaking up the contiguous copper on the top and bottom layer.
• Place the TAS5805M device away from the edge of the PCB when possible to ensure that the heat can travel away from the device on
all four sides.
• Avoid cutting off the flow of heat from the TAS5805M device to the surrounding areas with traces or via strings. Instead, route traces
perpendicular to the device and line up vias in columns which are perpendicular to the device.
• Unless the area between two pads of a passive component is large enough to allow copper to flow in between the two pads, orient it so
that the narrow end of the passive component is facing the TAS5805M device.
• Because the ground pins are the best conductors of heat in the package, maintain a contiguous ground plane from the ground pins to the
PCB area surrounding the device for as many of the ground pins as possible.
