FHP3131
0.4mA, 2.5V to 12V, 70MHz Rail-to-Rail Amplifier
Features at +5V
Description
■ 0.4mA supply current
The FHP3131 is a high-performance, voltage-feedback
amplifier that consumes only 0.4mA of supply current
while providing 70MHz of bandwidth and 50V/ꢀs slew
rate. The FHP3131 is designed to operate from 2.5V to
12V (±6V) supplies. The common mode voltage range
extends below the negative rail and the output provides
rail-to-rail performance.
■ 70MHz bandwidth at unity gain
■ Power down to 30μA
■ Output voltage range at RL = 1kΩ : 0.07V to 4.8V
■ Input extends below negative rail: -0.3V to 4V
■ 50V/ꢀs slew rate
■ 12nV/Hz input voltage noise
The FHP3131 is fabricated on a complementary bipolar
process. The combination of low power, rail-to-rail perfor-
mance, low voltage operation, and tiny package options
make this amplifier well suited for use in many general-
purpose, high-speed applications.
■ Small SOT23-6 and MicroPak™ -6 package options
■ Fully specified at +2.7V, +5V, and ±5V supplies
Applications
■ Portable/battery-powered applications
■ A/D buffer
For power sensitive applications, the FHP3131 offers
unparalleled dynamic performance. It also offers a shut-
down feature to lower the supply current draw below
30ꢀA. The FHP3131 is available in space-saving 6-lead
SOT23 or MicroPak™ packages and operates from -40°C
to +85°C.
■ Active filters
■ Portable test instruments
■ Set-top box
■ HDTV
■ DVD players and recorders
■ Coaxial cable drivers
■ Video driver

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable
above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,
extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute
maximum ratings are stress ratings only.

Driving Capacitive Loads
The Frequency Response vs. CL Figure 7 on page 8,
illustrates the response of the FHP3131. A small series
resistance (Rs) at the output of the amplifier, illustrated
in Figure 31, improves stability and settling performance.
Rs values in the Frequency Response vs. CL figure were
chosen to achieve maximum bandwidth with less than1dB
of peaking. For maximum flatness, use a larger Rs.

The maximum internal power dissipation allowed is
directly related to the maximum junction temperature. If
the maximum junction temperature exceeds 150°C for an
extendedtime,devicefailuremayoccur.WhiletheFHP3131
is short-circuit protected, 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:
Figure 31. Typical Topology for Driving
Capactive Loads
Enable/Disable Function
The FAN3131 offers an active-low disable pin that can be
used to lower its supply current. Leave the pin floating to
enable the part. Pull the disable pin to the negative supply
(which is ground in a single-supply application) to disable
the output. VON and VOFF thresholds are listed in the table
below. During the disable condition, the nominal supply
current drops to below 33μA and the output is at high
impedance with about 2.8pF capacitance.
Power Dissipation =
Is * (Vs+ - Vs-) + (Vs+ - VOUT(RMS)) * IOUT(RMS)
EQ. 1
where Is is the supply current, Vs+ is the positive supply pin
voltage, Vs- is the negative supply pin voltage, VOUT(RMS)
is the RMS output voltage, and IOUT(RMS) is the RMS
output current delivered to the load. Follow the maximum
power derating curves shown in Figure 33 below to
ensure proper operation.

1. To adequately drive 2Vpp into a 150Ω ground-centered
load, the FHP3131 must supply ±6.67mA of output
current. From the graph, the points created by (-6.7mA,
-1V) and (+6.7mA, +1V) both lie within the linear region
of the curve. So, the FHP3131 can drive 2Vpp into a
150Ω ground-centered load.

2. To adequately drive 5Vpp into a 100Ω load, the FHP3131
must supply ±25mAof output current. From the graph,
the point created by (+25mA, +2.5V) lies within the
linear region of the curve; however, the point created by
(-25mA, -2.5V) does not. So, the FHP3131 is not
capable of driving 5Vpp into a 100Ω ground-centered
load at ±5V.

Output
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 overdri-
ven and by how much the ranges are exceeded. The
FHP3131 typically recovers in less than 25ns from an
overdrive condition. Figure 34 shows the FHP3131 in an
overdriven condition.

Layout Considerations
General layout and supply bypassing play major roles
in high-frequency performance. Fairchild has evaluation
boards to guide high-frequency layout and aid device
testing and characterization. Follow the guidelines below
as a basis for high-frequency layout:
■ Include 6.8ꢀF and 0.01ꢀF ceramic capacitors.
■ Place the 6.8ꢀF capacitor within 0.75 inches of the
power pin.
■ Place the 0.01ꢀF 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.
Refer to the evaluation board layouts shown in Figures
36-39 for more information.

ing and layout of these devices:
