INRA = INRB and outputs combined OUTLA =
OUTLB, OUTRA = OUTRB.
ADDITIONAL INFORMATION
Output Filter
A passive two-pole low pass filter is used on the
DDX-2050 power outputs to reconstruct an
analog signal.
System performance can be
significantly affected by the output filter design
and choice of components. A filter design for
8Ω loads is shown in the Typical Application
Circuit in Figure 4.
Power Dissipation/Heat Sink Requirements
The power dissipation of the device will depend
primarily
on
the
supply
voltage,
load
impedance, and output modulation level.
The
DDX-2050
surface
mount
package
includes an exposed thermal pad on the bottom
of the device to provide a direct thermal path
from the integrated circuit to the PCB. This pad
must be soldered to a low thermal impedance
path at circuit ground potential for proper
operation, e.g.
a PCB ground plane.
For
continuous duty rated applications, careful
consideration must be made to the overall
thermal design.
For additional thermal design considerations,
