description  
The THS4081 and THS4082 are ultralow-power,  
high-speed voltage feedback amplifiers that are  
ideal for communication and video applications.  
These amplifiers operate off of a very low 3.4-mA  
quiescent current per channel and have a high  
output drive capability of 85ĂmA. The signal-  
amplifier THS4081 and the dual-amplifier  
THS4082 offer very good ac performance with  
175-MHz bandwidth, 230-V/µs slew rate, and  
43-ns settling time (0.1%). With total harmonic  
distortion (THD) of −64 dBc at f = 1 MHz, the  
THS4081 and THS4082 are ideally suited for  
applications requiring low distortion.

APPLICATION INFORMATION  
theory of operation  
The THS408x 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 38.

noise calculations and noise figure  
Noise can cause errors on very small signals. This is especially true when amplifying small signals, where  
signal-to-noise ratio (SNR) is very important. The noise model for the THS408x is shown in Figure 39. This  
model includes all of the noise sources as follows:  
e = Amplifier internal voltage noise (nV/Hz)  
n
IN+ = Noninverting current noise (pA/Hz)  
IN− = Inverting current noise (pA/Hz)  
e = Thermal voltage noise associated with each resistor (e = 4 kTR )

As the previous equations show, to keep noise at a minimum, small value resistors should be used. As the  
closed-loop gain is increased (by reducing R ), the input noise is reduced considerably because of the parallel  
G
resistance term. This leads to the general conclusion that the most dominant noise sources are the source  
resistor (R ) and the internal amplifier noise voltage (e ). Because noise is summed in a root-mean-squares  
S
n
method, noise sources smaller than 25% of the largest noise source can be effectively ignored. This can greatly  
simplify the formula and make noise calculations much easier to calculate.  
For more information on noise analysis, please refer to the Noise Analysis section in Operational Amplifier  
Circuits Applications Report (literature number SLVA043).

noise calculations and noise figure (continued)  
This brings up another noise measurement usually preferred in RF applications, the noise figure (NF). Noise  
figure is a measure of noise degradation caused by the amplifier. The value of the source resistance must be  
defined and is typically 50 in RF applications.

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 THS408x 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 41. A minimum value of 20 should work well for most applications. For  
example, in 75-transmission systems, setting the series resistor value to 75 both isolates any capacitance  
loading and provides the proper line impedance matching at the source end.

When receiving low-level signals, limiting the bandwidth of the incoming signals is often required. The simplest  
way to accomplish this is to place an RC filter at the noninverting terminal of the amplifier (see Figure 43).

circuit layout considerations  
To achieve the levels of high frequency performance of the THS408x, follow proper printed-circuit board high  
frequency design techniques. A general set of guidelines is given below. In addition, a THS408x evaluation  
board is available to use as a guide for layout or for evaluating the device performance.  
D
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.  
D
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.  
D
D
Sockets − Sockets are not recommended for high-speed operational amplifiers. 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.  
D
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-mount components, the problem with stray series inductance is greatly reduced. Second, the small  
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.

APPLICATION INFORMATION  
general PowerPADdesign considerations  
The THS408x is available packaged in a thermally-enhanced DGN package, which is a member of the  
PowerPADfamily of packages. This package is constructed using a downset leadframe upon which the die  
is mounted [see Figure 44(a) and Figure 44(b)]. This arrangement results in the lead frame being exposed as  
a thermal pad on the underside of the package [see Figure 44(c)]. Because this thermal pad has direct thermal  
contact with the die, excellent thermal performance can be achieved by providing a good thermal path away  
from the thermal pad.  
The PowerPADpackage allows for both assembly and thermal management in one manufacturing operation.  
During the surface-mount solder operation (when the leads are being soldered), the thermal pad can also be  
soldered to a copper area underneath the package. Through the use of thermal paths within this copper area,  
heat can be conducted away from the package into either a ground plane or other heat dissipating device.  
The PowerPADpackage represents a breakthrough in combining the small area and ease of assembly of the  
surface mount with the, heretofore, awkward mechanical methods of heatsinking.

general PowerPADdesign considerations (continued)  
Although there are many ways to properly heatsink this device, the following steps illustrate the recommended  
approach.  
Thermal pad area (68 mils x 70 mils) with 5 vias  
(Via diameter = 13 mils)  
Figure 45. PowerPAD PCB Etch and Via Pattern  
1. Prepare the PCB with a top side etch pattern as shown in Figure 45. There should be etch for the leads as  
well as etch for the thermal pad.  
2. Place five holes in the area of the thermal pad. These holes should be 13 mils in diameter. Keep them small  
so that solder wicking through the holes is not a problem during reflow.  
3. Additional vias may be placed anywhere along the thermal plane outside of the thermal pad area. This helps  
dissipate the heat generated by the THS408xDGN IC. These additional vias may be larger than the 13-mil  
diameter vias directly under the thermal pad. They can be larger because they are not in the thermal pad  
area to be soldered, so wicking is not a problem.  
4. Connect all holes to the internal ground plane.  
5. When connecting these holes to the ground plane, do not use the typical web or spoke via connection  
methodology. Web connections have a high thermal resistance connection that is useful for slowing the heat  
transfer during soldering operations. This makes the soldering of vias that have plane connections easier.  
In this application, however, low thermal resistance is desired for the most efficient heat transfer. Therefore,  
the holes under the THS408xDGN package should make their connection to the internal ground plane with  
a complete connection around the entire circumference of the plated-through hole.  
6. The top-side solder mask should leave the terminals of the package and the thermal pad area with its five  
holes exposed. The bottom-side solder mask should cover the five holes of the thermal pad area. This  
prevents solder from being pulled away from the thermal pad area during the reflow process.  
7. Apply solder paste to the exposed thermal pad area and all of the IC terminals.  
8. With these preparatory steps in place, the THS408xDGN IC is simply placed in position and run through  
the solder reflow operation as any standard surface-mount component. This results in a part that is properly  
installed.

The actual thermal performance achieved with the THS408xDGN in its PowerPADpackage depends on the  
application. In the example above, if the size of the internal ground plane is approximately 3 inches × 3 inches,  
then the expected thermal coefficient, θ , is about 58.4_C/W. For comparison, the non-PowerPADversion

general PowerPADdesign considerations (continued)  
The next consideration is the package constraints. The two sources of heat within an amplifier are quiescent  
power and output power. The designer should never forget about the quiescent heat generated within the  
device, especially multiamplifier devices. Because these devices have linear output stages (Class A-B), most  
of the heat dissipation is at low output voltages with high output currents. Figure 47 to Figure 50 show this effect,  
along with the quiescent heat, with an ambient air temperature of 50°C. Obviously, as the ambient temperature  
increases, the limit lines shown will drop accordingly. The area under each respective limit line is considered  
the safe operating area. Any condition above this line will exceed the amplifier’s limits and failure may result.  
When using V  
= 5 V, there is generally not a heat problem, even with SOIC packages. But, when using  
CC  
V
= 15 V, the SOIC package is severely limited in the amount of heat it can dissipate. The other key factor  
CC  
when looking at these graphs is how the devices are mounted on the PCB. The PowerPADdevices are  
extremely useful for heat dissipation. But, the device should always be soldered to a copper plane to fully use  
the heat dissipation properties of the PowerPAD. The SOIC package, on the other hand, is highly dependent  
on how it is mounted on the PCB. As more trace and copper area is placed around the device, θ decreases  
JA  
and the heat dissipation capability increases. The currents and voltages shown in these graphs are for the total  
package. For the dual amplifier package (THS4082), the sum of the RMS output currents and voltages should  
be used to choose the proper package. The graphs shown assume that both amplifier’s outputs are identical.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability  
information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
