Data Sheet
(V

The dynamic power is focused primarily within the output
stage driving the load. This value can be calculated as:
P
Assuming the load is referenced in the middle of the pow-
er rails or V
Figure 4 shows the maximum safe power dissipation in
the package vs. the ambient temperature for the pack-
ages available.
Driving Capacitive Loads
Increased phase delay at the output due to capacitive load-
ing can cause ringing, peaking in the frequency response,
and possible unstable behavior. Use a series resistance, R
between the amplifier and the load to help improve stability
and settling performance. Refer to Figure 5.
Table 1 provides the recommended R
tive loads. The recommended R

For a given load capacitance, adjust R
tradeoff between settling time and bandwidth. In general,

Overdrive Recovery
An overdrive condition is defined as the point when either
one of the inputs or the output exceed their specified volt-
age range. Overdrive recovery is the time needed for the
amplifier to return to its normal or linear operating point.
The recovery time varies, based on whether the input or
output is overdriven and by how much the range is ex-
ceeded. The LM358/LM324 will typically recover in less
than 30ns from an overdrive condition. Figure 6 shows the
LM358 in an overdriven condition.
