Application Information
Driving Capacitive Loads
The FREQUENCY RESPONSE VS. C
illustrates the response of the FHP3230 Family. A small
series resistance (R

Power Dissipation
The maximum internal power dissipation allowed is
directly related to the maximum junction temperature. If
the maximum junction temperature exceeds 150°C for an
extended time, device failure may occur.
The FHP3130, FHP3230, and FHP3430 are short-circuit
protected; however, this may not guarantee that the
maximum junction temperature (+150°C) is not exceeded
under all conditions. RMS Power Dissipation can be
calculated using the following equation:
Power Dissipation = I
where I
pin voltage, V
is the RMS output voltage, and I
output current delivered to the load.
Follow the maximum power derating curves shown in
Figure 28 below to ensure proper operation.

Overdrive Recovery
For an amplifier, an overdrive condition occurs when the
output and/or input ranges are exceeded. The recovery
time varies based on whether the input or output is overdriven
and by how much the ranges are exceeded. The
FHP3130/3230/3430 typically recovers in less than
50ns from an overdrive condition. Figure 29 shows the
FHP3230 in an overdriven condition.
