PCB Layout Guidelines
Minimize trace impedance of the power, ground and all output
traces for optimum performance. Voltage loss due to trace
resistance between the LM48100Q and the load results in
decreased output power and efficiency. Trace resistance be-
tween the power supply and ground has the same effect as a
poorly regulated supply, increased ripple and reduced peak
output power. Use wide traces for power supply inputs and
amplifier outputs to minimize losses due to trace resistance,
as well as route heat away from the device. Proper grounding
improves audio performance, minimizes crosstalk between
channels and prevents digital noise from interfering with the
audio signal. Use of power and ground planes is recommend-
ed.
Place all digital components and route digital signal traces as
far as possible from analog components and traces. Do not
run digital and analog traces in parallel on the same PCB lay-
er. If digital and analog signal lines must cross either over or
under each other, ensure that they cross in a perpendicular
fashion.
Exposed Dap Mounting
Considerations
The LM48100Q TSSOP-EP package features an exposed
die-attach (thermal) pad on its backside. The exposed pad
provides a direct heat conduction path from the die to the
PCB, reducing the thermal resistance of the package. Con-
nect the exposed pad to GND with a large pad and via to a
large GND plane on the bottom of the PCB for best heat dis-
tribution.
