Description
The FHP3132 (single) and FHP3232 (dual) are low-cost,
high-performance, voltage feedback amplifiers that consume
only 2.5mA of supply current per channel, while providing
±100mA of output current. These amplifiers are designed
to operate from 2.7V to 12V (±6V) supplies. The common-
mode voltage range includes the negative rail and the out-
put provides rail-to-rail performance.
The FHP3132 and FHP3232 are designed on a compli-
mentary bipolar process and provide 85MHz of bandwidth
at VOUT = 2Vpp and gain of 5V/V. The combination of low
power, rail-to-rail performance, low-voltage operation,
and tiny package options make these amplifiers well suited
for use in many general-purpose, high-speed applications.

Application Information
Driving Capacitive Loads
The Frequency Response vs. CL plot in Figure 10
illustrates the response of the FHP3132/3232. A small
series resistance (Rs) at the output of the amplifier,
illustrated in Figure 26, improves stability and settling
performance. Rs values in the Frequency Response vs.
CL plot were chosen to achieve maximum bandwidth with
less than 1dB of peaking. For maximum flatness, use a
larger Rs.

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 FHP3132 and FHP3232 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:
PD = Is * (Vs+ - Vs-) + (Vs+ - Vo(RMS)) * IOUT(RMS)
EQ. 1
where:
Is = the supply current
Vs+ = the positive supply pin voltage
Vs- = the negative supply pin voltage
Vo(RMS) = the RMS output voltage
IOUT(RMS) = the RMS output current delivered to the load.
Follow the maximum power derating curves shown in
Figure 27 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
FHP3132/3232 typically recovers in less than 50ns from
an overdrive condition. Figure 28 shows the FHP3132 in
an overdriven condition.
