THS4001CD - 270MHz High-Speed Voltage-Feedback Amplifier | TI
MPN： THS4001CD ✓ 啟用中THS4001CD 概覽
A voltage-feedback operational amplifier is a high-gain amplifier that uses voltage feedback to control its closed-loop response. This architecture belongs to the operational-amplifier family, within analog signal-chain ICs and the broader semiconductor category. Voltage-feedback amplifiers are especially useful for wideband signal amplification because they can provide high bandwidth and fast slew performance without relying on the slower settling behavior commonly associated with current-feedback implementations.
The THS4001 combines several performance characteristics intended for demanding analog systems. Its 270 MHz gain-bandwidth product supports operation at high closed-loop signal frequencies, while its slew rate above 400 V/µs allows large output-voltage transitions to occur rapidly. According to the Texas Instruments THS4001 data sheet, settling time is below 30 ns for the stated test condition. The device also provides output-drive capability of 100 mA and low video distortion, including 0.15° differential phase and 0.1% differential-gain bandwidth of 60 MHz.
The THS4001 operates across dual supply voltages from ±15 V down to ±2.5 V. Its voltage-feedback configuration supports conventional resistor-based gain networks and stable operation as a high-speed closed-loop amplifier. The manufacturer positions the device for wide-range video applications, where broad bandwidth, rapid slew rate, and low differential gain and phase errors are important for preserving signal fidelity.
Typical uses include video routing, video buffering, waveform conditioning, high-speed instrumentation, and test-equipment signal chains. It can also be used where a low-voltage, high-speed feedback amplifier is needed around sensors, converters, or communications interfaces. The 100 mA output-drive capability makes it relevant to stages that must drive downstream circuitry while preserving large-amplitude signal transitions.
Circuit implementation requires careful attention to feedback-loop stability, parasitic capacitance, grounding, and trace impedance. Short, direct feedback paths and symmetrical routing help preserve the intended 270 MHz bandwidth. Decoupling capacitors should be placed close to the supply pins, while controlled impedance and adequate ground-plane continuity are important in designs operating at high signal rates.
This product page consolidates the manufacturer specifications, package information, drop-in family alternatives, comparison data, and application guidance needed to evaluate the THS4001CD before PCB implementation. Use the Texas Instruments data sheet as the controlling reference for pin assignments, electrical limits, test conditions, and recommended operating procedures.

典型應用
THS4001CD 適用於 6 應用s: High-Speed Video Buffering, Waveform Conditioning, High-Speed Instrumentation, Video Distribution and Routing, Communications Signal Conditioning, Sensor and Converter Interface.
High-Speed Video Buffering
The THS4001CD is well suited to video buffering because its 270 MHz gain-bandwidth product and slew rate above 400 V/µs preserve large-amplitude, high-frequency signal transitions. According to the Texas Instruments THS4001 data sheet, differential phase is 0.15° and the 0.1% differential-gain bandwidth reaches 60 MHz. Place the amplifier in a conventional voltage-feedback network and keep feedback traces short to limit parasitic feedback. The 100 mA output-drive capability supports downstream video stages requiring stronger current than a conventional low-speed op amp can provide.
推薦
Waveform Conditioning
The THS4001CD can amplify and condition fast waveforms when signal fidelity and recovery time are important. Its 270 MHz gain-bandwidth product supports wide closed-loop bandwidth, while the slew rate above 400 V/µs allows output voltage to change rapidly during large steps. The manufacturer reports settling time below 30 ns under the specified test condition. Use short feedback components and a symmetrical input layout to limit parasitic feedback. Confirm the maximum signal amplitude and output-current demand before selecting the gain network and load.
推薦
High-Speed Instrumentation
The THS4001CD is appropriate for instrumentation front ends that must amplify signals without sacrificing bandwidth or transient response. Its 270 MHz gain-bandwidth product and over-400 V/µs slew rate provide a substantial performance margin for pulsed and high-frequency measurements. The device also offers a minimum dual supply of ±2.5 V, which can simplify dual-rail analog test systems. Keep input and feedback traces short, maintain continuous ground-plane return paths, and follow the manufacturer's pin descriptions when implementing the high-frequency layout.
推薦
Video Distribution and Routing
The THS4001CD can serve as a high-bandwidth routing stage in professional video equipment, where signal amplitude, phase accuracy, and channel consistency are critical. Its 60 MHz differential-gain bandwidth at 0.1% and 0.1 dB, together with 0.15° differential phase, supports low-distortion video amplification. The 8-pin SOIC package also allows placement near connector and routing networks. Maintain controlled trace geometry, provide a low-impedance ground connection, and avoid long parallel runs that can introduce coupling into the high-gain feedback loop.
推薦
Communications Signal Conditioning
The THS4001CD is useful in communications equipment for amplifying high-rate analog signals before digitization or further processing. Its 270 MHz bandwidth accommodates demanding baseband waveforms, and the slew rate above 400 V/µs reduces distortion on large transitions. The broad ±2.5 V to ±15 V supply range supports several rail plans. For implementation, use very short feedback paths, decouple each supply pin locally, and preserve impedance continuity into downstream converters. Check input and output common-mode limits against the circuit's signal excursion.
推薦
Sensor and Converter Interface
The THS4001CD can condition outputs from fast sensors, transducers, and converters when the interface requires high bandwidth and strong drive. The 270 MHz gain-bandwidth product minimizes additional signal shaping, while output-drive capability of 100 mA helps drive the next stage. Dual supplies spanning ±2.5 V to ±15 V allow integration with different analog rails. Confirm the source impedance and settling requirements of the driven circuit, then use short traces and local supply bypassing to avoid introducing instability or supply-related modulation.

設計說明
Keep the feedback network and amplifier output path physically short because parasitic capacitance in a high-gain 270 MHz feedback loop can create peaking or oscillation. Follow the pin-description table and recommended layout in the Texas Instruments data sheet, use a continuous ground plane, and route the two feedback components symmetrically. Avoid placing test points or long branches directly in the feedback node.
Place the supply-bypass capacitors as close as practical to the THS4001CD power pins and maintain a low-impedance ground return. The amplifier supports dual supplies from ±2.5 V to ±15 V, but stable operation still depends on adequate local energy storage and clean supply rails. Keep routing between the bypass network and device pins short, and avoid sharing narrow return paths with high-current output nodes.
Use controlled-impedance routing when the signal path is electrically long, and maintain symmetrical geometry around differential inputs. The THS4001 data sheet reports 0.15° differential phase and a 60 MHz differential-gain bandwidth at 0.1% and 0.1 dB, so small propagation differences can affect video timing and amplitude balance. Validate the final layout with time-domain reflectometry or equivalent measurement equipment.
Do not select a replacement solely by matching the eight-pin SOIC outline. Check supply limits, input and output common-mode limits, output-drive requirements, operating-temperature grade, and the intended ordering suffix. THS4001CDR has the same core amplifier family characteristics but represents a different commercial ordering option; confirm sourcing and delivery requirements rather than assuming the suffixes are interchangeable.
