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 1K

Ω load can accommodate an

unclipped swing.
