The dynamic power is focused primarily within the output

stage driving the load. This value can be calculated as:

Driving Capacitive Loads

Increased phase delay at the output due to capacitive load-

ing can cause ringing, peaking in the frequency response,

between the amplifier and the load to help improve stability

and settling performance. Refer to Figure 5.

Overdrive Recovery

An overdrive condition is defined as the point when ei-

ther 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 CLCx050 will typically recover in less

than 30ns from an overdrive condition. Figure 6 shows the

CLC1050 in an overdriven condition.
