ESTIMATING THE OUTPUT VOLTAGE SWING
It is important to keep in mind that the steady state output current will be less than the current available when
there is an input overdrive present. For steady state conditions, the Output Voltage vs. Output Current plot (
TYPICAL PERFORMANCE CHARACTERISTICS section) can be used to predict the output swing. Figure 56
and Figure 57 show this performance along with several load lines corresponding to loads tied between the
output and ground. In each cases, the intersection of the device plot at the appropriate temperature with the load
line would be the typical output swing possible for that load. For example, a 1KΩ load can accommodate an
output swing to within 250mV of V
−
and to 330mV of V
+
(V
S
= ±15V) corresponding to a typical 29.3V
PP
unclipped swing.
