9.2.3 Application Curves

Figure 5-1 in the Typical Characteristics section can be used as both an application curve and a typical characteristics plot in this example.

The Figure 9-2 and Figure 9-3 show characterization data for the Output slew rate for various CAPTRIM codes and across temperature. Customers can use these plots as reference for choosing the appropriate output slew rate based on the system requirement.
