General Information - 2

Therefore, both minimum transition time and slew rate must be considered when determining the actual transition time. This is shown in Figure 2-8, which shows the minimum transition time for a given slew rate as a horizontal line, and at about a 13.3% or greater load change, the slew rate increases from the minimum transition time to the Maximum transition time at a 100% load change. The actual transition time will be either the minimum transition time, or the total slew time (transition divided by slew rate), whichever is longer.

Use the following formula to calculate the minimum transition time (MinTT) for a given slew rate:

MinTT (in seconds) =

__________8__________

slew rate (in amps/second)

 

Use the following formula to calculate the maximum transition time (MaxTT) for a given slew rate:

MaxTT (in seconds) =

__________60__________

slew rate (in amps/second)

 

NOTE: In voltage mode, all minimum transition times are based on a low-capacitance current source. These transition times are affected by capacitive loading of the inputs. For example, a capacitance of 2.2 microfarads increases the 85 microsecond minimum transition time (shown in the table) to 110 microseconds.
