THS3061D Descripción general
A current-feedback amplifier, or CFA, is an analog amplifier architecture that uses feedback through an inverting input and offers high bandwidth and slew-rate performance for demanding signal chains. In the broader hierarchy, it belongs to the operational-amplifier family and the broader analog integrated-circuit category. Unlike a voltage-feedback amplifier, its bandwidth behavior depends strongly on the selected feedback resistor and gain setting.
The supplied data identifies a 300 MHz unity-gain bandwidth, 120 MHz 0.1 dB bandwidth at a gain of 2, 7000 V/us slew rate at 10 MHz, and approximately -81 dBc third-order distortion. It also identifies ±145 mA output current into 50 ohm. These characteristics make the THS3061D suitable for video line drivers, VDSL line drivers, and other applications requiring large, linear output signals.
The amplifier uses a current-feedback architecture rather than a conventional voltage-feedback input stage. In a typical implementation, the feedback network and input termination must be selected according to the manufacturer datasheet and the desired gain. The high slew rate can preserve large-signal amplitude in video and communication systems, while low distortion helps reduce signal degradation through the output stage.
THS3061D is supplied in an 8-pin SOIC package and is specified for an operating temperature range of -40°C to +85°C in the supplied product data. The product page identifies the D package as an 8-pin SOIC. The supplied distributor result reports an in-stock quantity of 6,240 pieces and a unit price of $12.3490, while current pricing and availability should be confirmed at purchase.
This page combines verified manufacturer and distributor information, application guidance, design notes, and an explicit distinction between confirmed drop-in alternatives and unavailable alternatives. The THS3061D is therefore best approached as a high-speed, high-voltage current-feedback amplifier for linear video and line-driver signal paths.

Aplicaciones típicas
THS3061D es adecuado para 6 aplicacións: Video Line Driver, VDSL Line Driver, High-Speed Analog Signal Conditioning, Communication Equipment Output Stage, Wideband Test and Measurement Front End, Industrial High-Speed Interface.
Video Line Driver
The THS3061D fits video line-driver requirements because its 300 MHz unity-gain bandwidth supports wideband signal amplification and its 7000 V/us slew rate handles large output transitions with low distortion. It can sit in a terminated video output path where signal amplitude and edge speed matter. The ±145 mA output-current figure into 50 ohms is useful for initial load assessment, but the actual output swing, termination, cable length, and channel bandwidth must be checked against the complete TI datasheet. Use short, controlled-impedance routing and verify the external gain network for the intended video standard.
Recomendado
VDSL Line Driver
THS3061D is explicitly suited to VDSL line-driving functions in the supplied Texas Instruments descriptions because it combines high slew rate with low distortion. Its current-feedback topology is appropriate for amplifying large, high-frequency signals when the feedback network is selected correctly. The 300 MHz unity-gain bandwidth provides substantial signal-path capability, while the 7000 V/us slew rate helps preserve transition speed. In a practical VDSL design, verify line impedance, attenuation, output swing, crosstalk, and the datasheet-recommended feedback resistor rather than assuming a standard voltage-feedback gain configuration.
Recomendado
High-Speed Analog Signal Conditioning
The THS3061D can condition high-speed analog signals when low distortion and rapid large-signal transitions are more important than very low static power. Its 7000 V/us slew rate and 120 MHz 0.1 dB bandwidth at gain 2 provide useful starting points for amplifier selection in instrumentation and communications front ends. Because it is a current-feedback device, the feedback resistor, gain, source impedance, and output loading determine the actual bandwidth and stability. Validate the complete gain-versus-frequency response and output compliance in the manufacturer datasheet before using it in a precision signal chain.
Recomendado
Communication Equipment Output Stage
THS3061D is relevant to communication equipment that requires a high-output-swing, fast-edge amplifier rather than a conventional low-bandwidth op amp. The single-channel current-feedback architecture supports applications where signal integrity and large-signal linearity are priorities. The verified data lists VDSL line drivers specifically and reports approximately -81 dBc third-order distortion, making distortion behavior an important selection criterion. Before implementation, confirm channel bandwidth, allowable distortion, output termination, supply rails, and thermal conditions against the complete Texas Instruments datasheet, especially if the output drives a transformer or long cable.
Recomendado
Wideband Test and Measurement Front End
The THS3061D may be useful in a wideband test front end when the source impedance, gain, and output loading allow a current-feedback amplifier to operate correctly. Its 300 MHz unity-gain bandwidth and 7000 V/us slew rate support fast signal acquisition and drive requirements, while the single amplifier simplifies a one-channel analog path. The device is not automatically suitable for every precision measurement because input offset, noise, stability, and accuracy data were not included in the supplied snippets. Use the complete datasheet for gain error, distortion, output swing, and compensation checks before instrument-grade deployment.
Recomendado
Industrial High-Speed Interface
THS3061D can support industrial interface circuitry that requires fast analog transitions and controlled distortion. Its high-voltage supply capability and high-slew-rate output stage are useful when driving a terminated line or an analog interface at higher signal bandwidth than ordinary op amps can provide. The verified product description specifically highlights video and VDSL rather than a broad industrial control role, so application qualification remains important. Check industrial temperature requirements, electromagnetic-emission behavior, grounding, and protection networks separately; only the -40°C to +85°C operating range was confirmed in the supplied data.

Notas de diseño
Do not treat THS3061D as a conventional voltage-feedback op amp. Its current-feedback architecture requires the feedback network to be selected for the intended gain, source impedance, and load. Verify the TI-recommended resistor values and stability conditions before layout. Changing gain without rechecking the feedback network can reduce bandwidth, alter peaking, or cause instability.
Place the amplifier, feedback components, and input or output termination according to the manufacturer layout guidance, with short high-bandwidth traces and a continuous ground reference. Keep sensitive feedback nodes compact and avoid long routes around the SOIC pins. Controlled-impedance routing and careful decoupling help preserve the intended behavior of a 300 MHz-bandwidth, high-slew-rate amplifier.
Confirm the actual supply rails, output swing, load current, and power dissipation in the complete Texas Instruments datasheet before connecting a 50-ohm or other terminated line. The supplied data lists ±145 mA into 50 ohms, but that condition is not a general output-current guarantee. Use short, adequately terminated output routing and provide local bypass capacitance according to the datasheet and system transients.
