description
The THS4001 is a very high-performance,
voltage-feedback operational amplifier especially
suited for a wide range of video applications. The
device is specified to operate over a wide range of
supply voltages from ± 15 V to ± 2.5 V. With a
bandwidth of 270 MHz, a slew rate of over
400 V/µs, and settling times of less than 30 ns, the
THS4001 offers the unique combination of high
performance in an easy to use voltage feedback
configuration over a wide range of power supply
voltages.

only 7.5 mA of quiescent current. Excellent professional video results can be obtained with the differential
gain/phase performance of 0.04%/0.15° and 0.1 dB gain flatness to 60 MHz. For applications requiring low
distortion, the THS4001 is ideally suited with total harmonic distortion of –72 dBc at f = 1 MHz.

APPLICATION INFORMATION
theory of operation
The THS4001 is a high speed, operational amplifier configured in a voltage feedback architecture. It is built
using a 30-V, dielectrically isolated, complementary bipolar process with NPN and PNP transistors possessing
f s of several GHz. This results in an exceptionally high performance amplifier that has a wide bandwidth, high
T
slew rate, fast settling time, and low distortion. A simplified schematic is shown in Figure 19.

APPLICATION INFORMATION
offset nulling
The THS4001 has very low input offset voltage for a high-speed amplifier. However, if additional correction is
required, an offset nulling function has been provided. By placing a potentiometer between terminals 1 and 8
of the device and tying the wiper to the negative supply, the input offset can be adjusted. This is shown in
Figure 20.

optimizing unity gain response
Internal frequency compensation of the THS4001 was selected to provide very wideband performance yet still
maintain stability when operated in a noninverting unity gain configuration. When amplifiers are compensated
in this manner there is usually peaking in the closed loop response and some ringing in the step response for
very fast input edges, depending upon the application. This is because a minimum phase margin is maintained
fortheG=+1configuration. Foroptimumsettlingtimeandminimumringing, afeedback resistorof 200Ω should
be used as shown in Figure 21. Additional capacitance can also be used in parallel with the feedback resistance
if even finer optimization is required.

APPLICATION INFORMATION
driving a capacitive load
Driving capacitive loads with high performance amplifiers is not a problem as long as certain precautions are
taken. The first is to realize that the THS4001 has been internally compensated to maximize its bandwidth and
slew rate performance. When the amplifier is compensated in this manner, capacitive loading directly on the
output will decrease the device’s phase margin leading to high frequency ringing or oscillations. Therefore, for
capacitive loads of greater than 10 pF, it is recommended that a resistor be placed in series with the output of
the amplifier, as shown in Figure 22. A minimum value of 20 Ω should work well for most applications. For
example, in 75-Ω transmission systems, setting the series resistor value to 75 Ω both isolates any capacitance
loading and provides the proper line impedance matching at the source end.

circuit layout considerations
In order to achieve the levels of high frequency performance of the THS4001, it is essential that proper
printed-circuit board high frequency design techniques be followed. A general set of guidelines is given below.
In addition, a THS4001 evaluation board is available to use as a guide for layout or for evaluating the device
performance.
Ground planes – It is highly recommended that a ground plane be used on the board to provide all
components with a low inductive ground connection. However, in the areas of the amplifier inputs and
output, the ground plane can be removed to minimize the stray capacitance.
Proper power supply decoupling – Use a 6.8-µF tantalum capacitor in parallel with a 0.1-µF ceramic
capacitor on each supply terminal. It may be possible to share the tantalum among several amplifiers
depending on the application, but a 0.1-µF ceramic capacitor should always be used on the supply terminal
of every amplifier. In addition, the 0.1-µF capacitor should be placed as close as possible to the supply
terminal. As this distance increases, the inductance in the connecting trace makes the capacitor less
effective. The designer should strive for distances of less than 0.1 inches between the device power
terminals and the ceramic capacitors.
Sockets – Sockets are not recommended for high speed op amps. The additional lead inductance in the
socket pins will often lead to stability problems. Surface-mount packages soldered directly to the
printed-circuit board is the best implementation.
Short trace runs/compact part placements – Optimum high frequency performance is achieved when stray
series inductance has been minimized. To realize this, the circuit layout should be made as compact as
possible thereby minimizing the length of all trace runs. Particular attention should be paid to the inverting
input of the amplifier. Its length should be kept as short as possible. This will help to minimize stray
capacitance at the input of the amplifier.

circuit layout considerations (continued)
Surface-mount passive components – Using surface mount passive components is recommended for high
frequency amplifier circuits for several reasons. First, because of the extremely low lead inductance of
surface-mountcomponents, theproblemwithstrayseriesinductanceisgreatlyreduced. Second, thesmall
size of surface-mount components naturally leads to a more compact layout thereby minimizing both stray
inductance and capacitance. If leaded components are used, it is recommended that the lead lengths be
kept as short as possible.
evaluation board
An evaluation board is available for the THS4001 (literature number SLOP119). This board has been configured
for very low parasitic capacitance in order to realize the full performance of the amplifier. A schematic of the
evaluation board is shown in Figure 23. The circuitry has been designed so that the amplifier may be used in
either an inverting or noninverting configuration. To order the evaluation board contact your local TI sales office
or distributor. For more detailed information, refer to the THS4001 EVM User’s Manual (literature number
SLOU017).
