THS3095D - High-Speed Current-Feedback Amplifier | Texas Instruments
Артикул: THS3095D ✓ АктивенTHS3095D Обзор
The current-feedback operational amplifier is a voltage-feedback amplifier subtype optimized for high-speed signal chains where gain bandwidth and stability can be affected by feedback impedance. Unlike a conventional voltage-feedback amplifier, the THS3095D uses a current-feedback topology that supports high slew rate, broad bandwidth, and low distortion when driven with suitable feedback resistors. It is used where signals must be amplified with high amplitude and fidelity, including pin drivers, power-FET drivers, and arbitrary-waveform generators.
Key features include a ±5 V to ±16 V supply range, 6000 V/µs slew rate, 310 mA output-current capability, and a dedicated power-down function. The power-down control can simplify power management in systems that need to disable the amplifier between active intervals. The wide supply range allows operation from split analog rails in communications, instrumentation, industrial, and test equipment.
For high-voltage output applications, the THS3095D is designed to preserve signal quality while driving demanding loads. Its low-distortion current-feedback architecture is particularly useful for large-signal waveform generation, where slew rate and output-current capability determine how faithfully large voltage steps can be reproduced. The device is not intended as a general-purpose precision-voltage-feedback amplifier; design calculations should use the manufacturer data sheet for feedback-resistor selection and stability verification.
Typical applications include arbitrary-waveform generators, pin and power-FET drivers, VDSL line-driver circuits, communication equipment, and high-speed instrumentation. The amplifier can be used where a high-voltage output swing and rapid transient response are more important than very low offset voltage. The 8-pin SOIC package makes the THS3095D suitable for conventional surface-mount PCB assembly.
The primary design consideration is the power-down interface and the feedback network. Keep the power-down control signal electrically defined, place the feedback resistors close to the amplifier pins, and use short, low-inductance connections for high-speed output stages. Review the manufacturer application guidance before selecting resistor values or adding capacitive load to the output. This page combines verified manufacturer and distributor information with practical selection and design guidance.

Типичное применение
THS3095D подходит для 6 применениеs: High-Voltage Arbitrary-Waveform Drivers, Power-FET Gate Drivers, VDSL and Communications Line Drivers, Pin Drivers for Instrumentation, High-Speed Analog Signal Conditioning, Industrial and Test Signal Drivers.
High-Voltage Arbitrary-Waveform Drivers
The THS3095D is well suited to arbitrary-waveform generator output stages because its 6000 V/µs slew rate allows large output transitions to follow the commanded waveform quickly. The 310 mA output-current capability provides additional drive margin for resistive and reactive test loads. Use the device behind the signal source or DAC output, with a feedback network selected from the manufacturer guidance. Because the current-feedback amplifier can amplify parasitic capacitance and layout delay, keep the feedback loop compact and verify output stability across the intended frequency range. The power-down function can also disable the driver during idle generator intervals, reducing quiescent current from 9.5 mA to 500 µA.

Power-FET Gate Drivers
The THS3095D can serve as a high-speed driver for power MOSFETs and other switching devices that require large gate voltage swings. Its 6000 V/µs slew rate helps the output follow fast edge commands, while the 310 mA output rating supports transient gate-drive demand more effectively than a low-current general-purpose amplifier. The supply range of ±5 V to ±16 V permits split-rail drive arrangements used in high-side or bipolar designs. Care is required around gate protection, source-referenced return paths, and parasitic inductance; the feedback network and output routing should follow the manufacturer’s high-current feedback-layout recommendations.

VDSL and Communications Line Drivers
The THS3095D is suitable for communications line-driver circuitry requiring high-voltage, low-distortion output signals. The verified THS309x family information specifically identifies VDSL line drivers as an application, while the 6000 V/µs slew rate helps preserve large-signal waveforms and the ±5 V to ±16 V supply range supports high-line-voltage architectures. A current-feedback implementation requires deliberate feedback-resistor selection and short output routing to avoid instability. Designers should also account for cable capacitance, line protection, connector parasitics, and thermal rise when driving the 310 mA output capability at the upper limit.

Pin Drivers for Instrumentation
The THS3095D can provide the high-voltage, high-speed drive required by instrumentation and semiconductor test pin-driver circuits. A 6000 V/µs slew rate supports rapid transitions, and 310 mA output current provides a practical drive reserve for capacitive and resistive fixtures. Because the device uses a current-feedback topology, feedback resistors and compensation must be selected for the intended load rather than copied from a voltage-feedback amplifier. Keep the output path short, provide a low-impedance return, and validate ringing with an oscilloscope. The power-down pin is useful when the test system does not need the driver active during idle periods.

High-Speed Analog Signal Conditioning
The THS3095D is useful in high-speed analog front ends where the input bandwidth, output swing, and slew rate must be balanced. Its low-distortion current-feedback architecture is intended for large linear signals rather than only small-signal precision amplification. A 6000 V/µs slew rate helps preserve fast waveform features, while the 310 mA output rating offers drive for downstream instrumentation. The design must account for source impedance, feedback resistor values, capacitance at the input and output, and stable grounding. The active quiescent current of 9.5 mA should also be included in thermal and battery-budget calculations.
Рекомендуется
Industrial and Test Signal Drivers
The THS3095D can drive large, rapidly changing voltages in industrial test and measurement equipment where a normal precision operational amplifier may be too slow. The ±5 V to ±16 V supply range supports higher-amplitude rails, the 6000 V/µs slew rate handles fast edges, and the 310 mA output capability supports moderate loads. A power-down-controlled instrument can reduce standby consumption from 9.5 mA to 500 µA when the output stage is inactive. Designers should verify output-current derating, safe operating limits, thermal performance, and connector or fixture capacitance, since high slew rate can expose layout-related ringing and EMI issues.

Заметки по проектированию
The THS3095D uses a current-feedback topology, so the feedback network and its physical placement are critical. Keep the feedback resistor close to the relevant amplifier pin, use a short return path for the output reference, and minimize the area enclosed by the high-frequency feedback loop. Route the output separately from sensitive input and reference nodes. Verify ringing and stability with the intended load, output amplitude, and supply decoupling rather than relying only on nominal simulation results.
Provide local supply decoupling close to the power pins and use the manufacturer-specified capacitor types and values. The THS3095D supports split supplies from ±5 V to ±16 V, but the usable output swing is not equal to the full rail-to-rail range. The verified device rating includes up to 310 mA output current and 6000 V/µs slew rate; use those values to check regulator capability, cable or trace resistance, and thermal rise. Do not use the maximum output-current figure without considering voltage drop and heat dissipation.
Do not treat THS3095D as a conventional unity-gain voltage-feedback operational amplifier. Its current-feedback behavior makes resistor values, source impedance, load capacitance, and gain stability interdependent. Use the manufacturer’s recommended feedback network as the starting point and validate the final board. In addition, the power-down pin should be driven to a defined logic state, and downstream circuitry should be checked for behavior while the amplifier is in standby.
