THS3202D Présentation
A current-feedback amplifier is a voltage-feedback amplifier subclass that uses an inverting input as the principal high-frequency feedback node. Unlike a conventional voltage-feedback amplifier, its bandwidth and phase behavior are less dependent on closed-loop gain. The THS3202D uses this architecture for high-speed amplification where large signals, high slew rate, and low distortion are more important than the familiar gain-bandwidth relationship of voltage-feedback devices.
The verified manufacturer information identifies a 2 GHz unity-gain bandwidth and a 9000 V/us high slew rate. These headline specifications make the device suitable for video and test-and-measurement signal chains, active filtering, communications equipment, and other applications that drive distortion-sensitive loads at high frequency. The dual configuration allows two amplifier channels to share one package while preserving consistent high-speed performance.
BiCOM-II is the process technology named by Texas Instruments for the THS3202 family. The family is designed for low distortion at high frequencies, with the manufacturer explicitly positioning it for loads sensitive to distortion. Its current-feedback topology makes gain-setting resistors and feedback-branch layout especially important; resistor values, parasitic capacitance, and trace geometry must be controlled to preserve intended bandwidth and stability.
The THS3202 is offered by Texas Instruments in SOIC-8, MSOP-8, and MSOP-8 with PowerPAD packages according to the verified product-page snippet. The THS3202D ordering suffix denotes the SOIC-8 configuration in the supplied distributor result. Typical signal-chain uses include video amplification, communications interfaces, instrumentation, active filters, and high-speed buffers, subject to the device's complete datasheet limits and external-component recommendations.
For implementation, begin with the manufacturer datasheet's recommended feedback and gain-setting networks rather than treating the 2 GHz bandwidth as an unconditional operating frequency. Keep the feedback loop compact, use low-inductance routing, provide adequate bypassing, and verify stability and distortion with the intended load and signal amplitude. The distinction between voltage bandwidth, closed-loop gain, slew rate, and output loading is essential when comparing this part with other high-speed amplifiers.
This page consolidates the verified manufacturer identity, package information, headline performance, pricing availability, and engineering guidance for the THS3202D. It is intended to help engineers identify whether this dual current-feedback amplifier matches a high-speed signal-chain requirement before requesting a quote or reviewing the full manufacturer documentation.

Applications typiques
THS3202D convient pour 6 applications: High-Speed Video Signal Conditioning, Communications Interface Amplification, Active Filtering, Test and Measurement Front Ends, High-Speed Buffering, Precision Waveform Drivers.
High-Speed Video Signal Conditioning
The THS3202D fits video signal-conditioning paths that benefit from a verified 2 GHz unity-gain bandwidth and 9000 V/us slew rate. It can amplify or buffer video-like waveforms when the selected gain, cable capacitance, and termination network remain within the device's stable operating region. The current-feedback topology makes the inverting feedback branch critical: use the manufacturer's recommended resistor values and keep the feedback loop compact. Compared with a lower-bandwidth amplifier, the THS3202D offers more small-signal bandwidth and slew capability, but its fast behavior makes PCB parasitics, load capacitance, and supply bypassing important design checks.
Recommandé
Communications Interface Amplification
For communications interfaces, the THS3202D is useful where edge rates and waveform fidelity require more bandwidth than a general-purpose operational amplifier. Its verified 2 GHz unity-gain bandwidth and 9000 V/us slew rate support high-frequency amplification, while the dual-channel package can simplify paired transmit or receive signal paths. The engineer must still set the feedback network for the intended gain and confirm the device's common-mode and output-drive limits against the line interface. Short traces, controlled return paths, and local supply decoupling are essential because the current-feedback amplifier's high-frequency behavior is strongly influenced by layout parasitics.
Recommandé
Active Filtering
The THS3202D can be used in active-filter stages operating well above the bandwidth of conventional op amps. Its 2 GHz unity-gain bandwidth provides a useful starting point for high-frequency filter design, and its 9000 V/us slew rate helps preserve large-signal shape across the filter. Because current-feedback amplifiers require frequency-dependent feedback-element selection, the resistor and capacitor values should come from a verified design method or manufacturer guidance. Simulate stability, gain peaking, group delay, and output loading, then verify the filter across temperature and supply variations before using it as a precision measurement element.
Recommandé
Test and Measurement Front Ends
The THS3202D is appropriate for high-speed instrumentation front ends when the measured signal requires wide bandwidth and the front end must preserve low distortion. The 9000 V/us slew rate can reduce slew-induced waveform error for fast, large-amplitude signals, while the dual amplifier configuration allows two channels to share one package. Input and output loading, source impedance, common-mode range, and noise must be evaluated for each measurement path. Keep the sensitive input node short, separate high-current return paths, and validate gain calibration across the complete frequency range rather than relying only on the unity-gain bandwidth number.
Recommandé
High-Speed Buffering
Use the THS3202D for high-speed buffering when the source and destination require a 2 GHz-class amplifier and the load is compatible with the output-drive capability. Its dual channels can buffer two related signals, while the 9000 V/us slew rate helps maintain edge fidelity in fast systems. Current-feedback buffer configurations still require careful feedback implementation and may have gain-dependent stability behavior. Confirm output swing, load capacitance, and supply headroom in the manufacturer data before connecting cables or downstream high-current stages. A fast buffer reduces bandwidth limitations but does not remove the need for termination and impedance control.
Recommandé
Precision Waveform Drivers
The THS3202D can drive precision and instrumentation-oriented waveforms when the output amplitude and edge rate remain within the verified electrical limits. The 9000 V/us slew rate is the principal benefit for reducing large-signal edge distortion, while the 2 GHz unity-gain bandwidth supports high-frequency small-signal behavior. The circuit should include appropriate source and load analysis, output protection where needed, and local decoupling. Because the verified data does not provide output-current, output-swing, or noise specifications, those values must be read from the official datasheet before defining a driver requirement.

Notes de conception
Treat the current-feedback network as a high-frequency signal path rather than a generic op-amp feedback branch. Keep the inverting input, feedback resistor, and output connection physically short, use low-inductance routing, and avoid long copper stubs. Place bypass capacitors close to the supply pins and follow the manufacturer layout guidance for the 8-SOIC footprint. Validate AC gain, phase margin, and pulse response on the intended load.
Do not infer usable bandwidth from the 2 GHz unity-gain number alone. Evaluate closed-loop gain, feedback impedance, source and load capacitance, cable length, and output termination. A fast current-feedback amplifier can expose layout parasitics and incorrect resistor values as peaking or ringing. Start with the manufacturer-recommended topology, then tune only after measuring gain, phase, distortion, and stability with the final board and load.
The verified supply range is +/-3.3 V to +/-7.5 V, but current, quiescent power, output swing, and thermal limits are not present in the supplied search data. Confirm those values in the official datasheet before sizing the rails or estimating dissipation. Use stable, low-noise supply connections and local decoupling; do not derive a thermal design from the bandwidth and slew-rate figures alone.
Informations de conformité
The supplied verified search results do not state THS3202D RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the manufacturer brand or package.
