THS4001ID - 270MHz High-Speed Voltage-Feedback Op Amp
MPN: THS4001ID ✓ NakahandaTHS4001ID Ulas
A voltage-feedback operational amplifier is an amplifier category in which the inverting input provides the feedback path. This architecture supports closed-loop gain control while maintaining high bandwidth and slew rate. Within the integrated-circuit hierarchy, the THS4001ID belongs to the amplifier IC, operational amplifier, and high-speed analog signal-chain categories.
The principal performance characteristics are 270 MHz small-signal bandwidth, greater than 400 V/μs slew rate, less than 30 ns settling time, and 100 mA output drive. Video performance includes 60 MHz bandwidth with 0.1 dB differential gain variation, 0.15° differential phase, and very low distortion. These figures make the amplifier appropriate for video routing, active filtering, pulse shaping, and test-equipment input stages.
The THS4001 operates from dual supplies ranging from ±2.5 V to ±15 V. Its voltage-feedback configuration permits gain to be established with external resistors while retaining high-speed performance. The combination of wide bandwidth and slew rate reduces distortion for large or rapidly changing signals, while the settling-time specification is particularly useful when accurate waveform recovery is required after a transition.
Typical uses include professional video distribution, broadcast and monitoring equipment, high-resolution imaging interfaces, active filters, laboratory instrumentation, and general-purpose high-speed signal conditioning. Its 8-pin SOIC package supports conventional surface-mount assembly, although careful component placement and short feedback paths are important at these operating frequencies.
For high-speed layouts, minimize trace lengths around the input and feedback pins, use a low-inductance ground reference, and place input and feedback components close to the amplifier. Avoid long PCB routes and excessive capacitance on sensitive input nodes, because parasitic reactance can reduce bandwidth and increase ringing.
This product page combines the manufacturer specifications with application guidance, pin-layout requirements, comparison information, and practical design considerations. It is intended to help engineers determine whether the THS4001ID provides the required bandwidth, slew rate, voltage range, package, and drive capability without overlooking layout-related performance losses.

Professional Video Routing
The THS4001ID is well suited to professional video routing because its 270 MHz bandwidth preserves high-frequency signal content while its slew rate above 400 V/μs supports rapid transitions. The device also provides 60 MHz video bandwidth at 0.1 dB differential-gain variation, 0.15° differential phase, and low distortion, helping maintain amplitude and phase relationships through cascaded routing stages. Place feedback components close to the device and maintain short, grounded signal paths to minimize parasitic effects at video frequencies.

High-Speed Active Filtering
The THS4001ID can implement high-order active filters where a conventional low-frequency amplifier would introduce excessive bandwidth or phase error. Its 270 MHz gain-bandwidth product provides design margin above the filter corner frequency, while slew rate above 400 V/μs helps preserve low distortion for large input signals. The less-than-30 ns settling characteristic also improves transient performance in pulse and waveform-shaping filters. Component tolerances and parasitic capacitance should be included in the actual response simulation.
Inirekomenda
Test and Measurement Front Ends
The THS4001ID suits oscilloscope drivers, signal generators, and measurement interfaces that must preserve fast edges. Its bandwidth of 270 MHz, output drive of 100 mA, and settling time below 30 ns support accurate recovery after input transitions. The dual supply range of ±2.5 V to ±15 V provides flexibility for centered bipolar signals and larger swing requirements. Use short coaxial-style PCB routes, a continuous ground reference, and local supply bypassing to minimize measurement errors.

Video Monitoring and Gain Control
The THS4001ID can serve as a gain and distribution stage in professional monitoring systems where color-subcarrier and video timing integrity must be preserved. Its 60 MHz video bandwidth with only 0.15° differential phase indicates low phase error, while the 270 MHz small-signal bandwidth supports wider-band signal paths. The over-400 V/μs slew rate reduces edge distortion, making it useful ahead of imaging or processing stages. Check output swing, load capacitance, and stability against the gain setting before deployment.
Inirekomenda
Imaging and Broadcast Interfaces
The THS4001ID is appropriate for high-speed interfaces in broadcast equipment, camera electronics, and imaging systems that transmit composite or other analog video signals. Low differential gain and phase errors help prevent brightness, color, and timing-related distortion across gain stages, while the high output-drive capability supports downstream stages without severe loading. The 8-pin SOIC package simplifies conventional surface-mount assembly, although controlled layout remains essential to achieve the advertised high-frequency performance.
Inirekomenda
Pulse and Waveform Conditioning
The THS4001ID can condition short pulses and fast transient signals where rise-time limits would otherwise distort the measured waveform. Slew rate above 400 V/μs allows the output to follow large changes rapidly, while settling time below 30 ns supports accurate recovery before the next event. The 100 mA output-drive specification is useful for moderate capacitive loads, although load impedance and capacitive loading can affect stability. Use short feedback traces and place termination close to the relevant driver or receiver.

Talaan ng Disenyo
Keep the op-amp input, output, and feedback components close to their corresponding THS4001ID pins. At 270 MHz bandwidth, long traces can behave as transmission-line structures and add inductance, capacitance, and phase delay. Use short, direct routes, a continuous ground plane, and a symmetrical feedback layout. Place termination and decoupling components near the associated pins rather than distributing them around the board.
Account for parasitic capacitance introduced by sockets, probe pads, protection devices, and long connector traces. These capacitances interact with the closed-loop gain and can reduce bandwidth or cause ringing, particularly where the feedback factor is small. Evaluate the assembled board with an oscilloscope using short probe grounds, and compare measured step response with the expected less-than-30 ns device settling behavior.
Decouple each supply connection close to the amplifier and keep the return current within the same ground reference used by the signal path. The device supports ±2.5 V to ±15 V operation, but the maximum allowable input-output differential voltage and output swing must not be exceeded during startup or fault conditions. Use series resistance or appropriate protection where a downstream fault could drive the input beyond its rating.
Calculate dissipation from the actual output waveform, including quiescent consumption and output-stage current, rather than treating the 100 mA output-drive figure as a continuous operating point. Use the SOIC land pattern and copper area to minimize junction temperature rise. Reduce supply span, output swing, or load current when thermal headroom is limited, and verify the worst-case ambient and supply conditions.
