Data Sheet
The dynamic power is focused primarily within the output
stage driving the load. This value can be calculated as:
Assuming the load is referenced in the middle of the power
rails or V
The CLC1009 is short circuit protected. However, this may
not guarantee that the maximum junction temperature
(+150°C) is not exceeded under all conditions. Figure 7
shows the maximum safe power dissipation in the package
vs. the ambient temperature for the packages available.
Driving Capacitive Loads
Increased phase delay at the output due to capacitive loading
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 8.

For a given load capacitance, adjust R

additional overshoot and ringing.
Overdrive Recovery
An overdrive condition is defined as the point when either
one of the inputs or the output exceed their specified
voltage 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 exceeded. The CLC1005, CLC1015, and CLC2005 will
typically recover in less than 20ns from an overdrive
condition. Figure 9 shows the CLC2005 in an overdriven
condition.
