Overdrive Recovery
1. Short -Vs to ground.
An overdrive condition is defined as the point when either 2. Use C3 and C4, if the -V pin of the amplifier is not

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 CLC1010 and CLC2010 will typically recover
in less than 60ns from an overdrive condition.
directly connected to the ground plane.
Layout Considerations
General layout and supply bypassing play major roles in
high frequency performance. CADEKA has evaluation
boards to use as a guide for high frequency layout and as
an aid in device testing and characterization. Follow the
steps below as a basis for high frequency layout:
Include 6.8µF and 0.1µF ceramic capacitors for power
supply decoupling
▪
Place the 6.8µF capacitor within 0.75 inches of the power pin
▪
Place the 0.1µF capacitor within 0.1 inches of the power pin
▪
Remove the ground plane under and around the part,
especially near the input and output pins to reduce
parasitic capacitance
▪

Minimize all trace lengths to reduce series inductances
