MOTOROLA ANALOG IC DEVICE DATA
of each of the three curves is defined by the power level at
which 10% distortion occurs. The center flat portion of each
curve is defined by the maximum output current capability of
the MC34119. The right (descending) portion of each curve is
defined by the maximum internal power dissipation of the IC
at 25
°
C. At higher ambient temperatures, the maximum load
power must be reduced according to the above equations.
Operating the device beyond the current and junction
temperature limits will degrade long term reliability.
Layout Considerations
Normally a snubber is not needed at the output of the
MC34119, unlike many other audio amplifiers. However, the
PC board layout, stray capacitances, and the manner in
which the speaker wires are configured, may dictate
otherwise. Generally, the speaker wires should be twisted
tightly, and not more than a few inches in length.
