THS3062D - Dual 7000V/us High-Speed Amplifier | TI
MPN： THS3062D ✓ 啟用中THS3062D 概覽
A current-feedback operational amplifier is a voltage-amplifier architecture in which the feedback impedance and closed-loop gain determine bandwidth and stability. Current-feedback amplifiers belong to the operational-amplifier, analog-signal-conditioning, and semiconductor hierarchies. They are particularly useful when a system requires large output voltage swings, fast edge rates, low signal distortion, or driving terminated analog lines.
The THS3062D combines several performance-critical characteristics. Its 300 MHz unity-gain bandwidth supports wideband signal amplification, while its 7000 V/us slew rate allows large-amplitude signals to change rapidly without immediately becoming slew-rate limited. The 120 MHz 0.1 dB bandwidth applies at a gain of 2, and the output-current capability of ±145 mA into 50 ohms provides useful drive for demanding loads. The dual configuration also allows two high-speed amplifier channels in one package.
The THS3062 uses Texas Instruments BICOM-1 process technology. Because it is a current-feedback amplifier, closed-loop bandwidth and stability depend on the feedback network and gain setting rather than following the same closed-loop bandwidth behavior as a conventional voltage-feedback amplifier. Designers should therefore follow the manufacturer feedback-network recommendations and observe resistance and capacitance constraints around the inverting input.
Typical uses include video line drivers, VDSL line drivers, instrumentation amplifiers, high-speed filter stages, waveform-driver circuits, and analog communications equipment. Its combination of high voltage swing, fast slew rate, and dual-channel integration is particularly appropriate when two wideband signals must be amplified without using separate single-channel packages.
When laying out a THS3062D board, keep feedback components close to the relevant amplifier pins and minimize parasitic capacitance at the inverting input. Decoupling capacitors should be placed close to the supply pins, and the SOIC thermal limitations should be considered when operating near the maximum output current.
This page combines manufacturer and distributor data with same-footprint amplifier alternatives, application guidance, and design considerations to provide practical information beyond a basic ordering-table summary.

Video Line Drivers
The THS3062D fits video line-driver stages because it combines a 7000 V/us slew rate with output-current capability of ±145 mA into 50 ohms. Its 120 MHz 0.1 dB bandwidth at a gain of 2 provides substantial bandwidth for wideband video signals, while the dual configuration supports two related output channels. In a practical implementation, the amplifier is placed in a current-feedback topology with manufacturer-recommended feedback values. The main benefit is rapid edge reproduction without the severe slew-rate compression associated with lower-speed operational amplifiers. Designers should still verify source and load impedance, output swing, and video-specific distortion against the complete Texas Instruments datasheet.

VDSL Line Drivers
The THS3062D is appropriate for VDSL line-driving circuits that require large output-voltage transitions at high frequency. Its 7000 V/us slew rate, 300 MHz unity-gain bandwidth, and ±145 mA into 50 ohms output capability help preserve signal integrity when driving terminated lines. The device is implemented as a dual current-feedback amplifier, allowing two line channels to share a package and decoupling arrangement. Compared with a general-purpose voltage-feedback amplifier, the documented high slew rate can limit edge-rate distortion. Before release, the circuit should be checked for the required line impedance, output compliance, gain-bandwidth stability, and thermal performance in the selected SOIC layout.

High-Speed Instrumentation Amplification
The THS3062D can support instrumentation and measurement front ends that need substantially more bandwidth than ordinary precision amplifiers provide. Its 300 MHz unity-gain bandwidth and 7000 V/us slew rate preserve large-amplitude, fast-moving signals, while the dual package can amplify two complementary or sequential channels. The amplifier’s current-feedback architecture requires careful selection of feedback resistance and compensation for the intended closed-loop gain. Input offset, noise density, and common-mode limits were not available in the supplied summaries, so those parameters must be verified before using the device for precision dc measurements. It is best suited to wideband instrumentation rather than unverified low-noise measurement claims.

High-Speed Filter Stages
The THS3062D can serve as the active element in high-speed analog filter stages where a conventional op amp would slew-limit the output. Its 300 MHz unity-gain bandwidth provides ample closed-loop frequency range, and its 7000 V/us slew rate supports large-signal operation beyond the range of many precision amplifiers. In a current-feedback filter, the feedback impedance determines both gain and stability, so component values should follow the manufacturer’s guidance. The dual channel permits two related filter paths, such as signal and reference channels, without adding another package. Actual passband peaking requires simulation with the selected topology, component tolerances, source impedance, and load before the circuit is released.

Analog Communications Equipment
The THS3062D is suitable for transmit and interface stages in analog communications equipment requiring high bandwidth, large voltage swing, and low distortion. Its ±145 mA output-current capability into 50 ohms is particularly relevant when driving terminated analog circuitry, while the 7000 V/us slew rate helps maintain clean transitions. Two amplifiers are integrated in the 8-pin SOIC, which can reduce board area in multichannel radio, modem, or line-interface designs. Because the available summaries do not verify noise, offset, or common-mode figures, those specifications must be checked in the manufacturer datasheet. PCB planning should prioritize short feedback paths, close supply bypassing, and controlled return currents.
推薦
Precision Waveform Drivers
The THS3062D can drive laboratory, industrial, and control waveforms where accurate amplitude and rapid slew performance are important. Its high 7000 V/us slew rate prevents large output steps from becoming rounded, and the ±15 V supply capability provides useful output-voltage range for bipolar signals. The device may be used with external gain and offset networks for waveform conditioning, but the exact input common-mode range and output swing must be checked for the selected operating point. Current-feedback topology also demands attention to feedback resistance and stability compensation. The dual amplifier permits complementary outputs or two independently configured channels when the system needs one package rather than two single amplifiers.

主要差異化特點
- High slew rate for large-signal video and line-driving use (對比THS3122)
- Dual-channel integration in an 8-pin SOIC (對比OPA2691)
- Documented high-current output capability (對比OPA2694)
- Wideband closed-loop performance (對比OPA2684)
設計說明
Place the feedback network and any compensation components directly between the appropriate output and inverting-input pins. Keep the inverting-input copper short and minimize parasitic capacitance because the THS3062D uses current feedback. Route the two channels to reduce shared-impedance coupling where independent measurements are required.
Connect both supply pins to a clean ±15 V source where applicable and place the datasheet-recommended bypassing capacitors close to pins 4 and 8. The supplied data identifies 30 V across the supply terminals, but does not provide a complete absolute-maximum table or transient requirements; use the manufacturer document to verify operating and absolute limits.
Do not assume that an 8-pin SOIC can dissipate the full ±145 mA into 50 ohms output capability under every condition. The Texas Instruments datasheet excerpt specifically notes that standard SOIC thermal impedance is too large for some useful applications. Estimate dissipation from actual output voltage, load current, and quiescent current, then verify the resulting junction temperature with the package thermal data.
Do not substitute a current-feedback amplifier by package name alone. Confirm the exact pinout, supply range, input common-mode range, output swing, gain-bandwidth behavior, and feedback resistance of every proposed alternative. The supplied TI E2E discussion identifies candidates for investigation, but it does not establish unconditional pin-to-pin equivalence for every candidate.
