THS4061CD - 180MHz High-Drive Amplifier | Texas Instruments
N.º de pieza: THS4061CD ✓ ActivoTHS4061CD Descripción general
A high-speed voltage-feedback amplifier is an operational amplifier whose closed-loop bandwidth depends directly on the selected feedback network. It belongs to the broader hierarchy of analog ICs, signal-chain amplifiers, and voltage-feedback amplifiers. Unlike general-purpose precision amplifiers optimized mainly for offset and noise, this device emphasizes speed, slew rate, drive current, and stable operation across both inverting and noninverting gain configurations.
The THS4061CD's 180 MHz bandwidth supports the transmission of substantially higher-frequency signals than conventional low-speed op amps. Its 400 V/µs slew rate allows large output transitions to occur quickly, while the 40 ns 0.1% settling specification helps reduce the time required for signals to settle after a step. A typical output current of 115 mA gives the amplifier sufficient drive capability for downstream video, communications, and imaging stages.
Video performance is a key feature of this device family. The manufacturer identifies a 75 MHz small-signal bandwidth at 0.1 dB, differential gain distortion of 0.02%, and differential phase error of 0.02°. These characteristics are relevant in video paths where amplitude and phase uniformity contribute to signal fidelity. The amplifier is also stable at all gains in both inverting and noninverting configurations, simplifying feedback selection.
Typical applications include video routing and monitoring, communications-interface signal conditioning, imaging systems, test and measurement equipment, and high-speed analog front ends. Its combination of bandwidth, slew rate, settling performance, and output drive makes it useful when the signal path must preserve waveform shape at frequencies well above those supported by general-purpose amplifiers.
When designing around the THS4061CD, use short feedback paths, maintain symmetrical routing where practical, and place input and output decoupling close to the device. The 8-pin SOIC requires careful attention to high-frequency layout because parasitic inductance, capacitance, and ground-loop impedance can reduce the benefit of the specified bandwidth and settling performance.
This product page combines the manufacturer's principal performance figures, practical high-speed layout guidance, package information, and a strict drop-in alternative review. It is designed to help engineers compare bandwidth, slew rate, drive current, package compatibility, and application fit before committing a THS4061CD to an analog signal-chain design.

Aplicaciones típicas
THS4061CD es adecuado para 6 aplicacións: Video Signal Conditioning, Communications Signal Conditioning, Imaging and Sensor Signal Paths, High-Speed Instrumentation, Active Filtering, Industrial Control Signal Conditioning.
Video Signal Conditioning
The THS4061CD fits video buffers, distribution amplifiers, and gain stages requiring both wide bandwidth and strong drive. Its 75 MHz bandwidth at 0.1 dB, 0.02% differential gain distortion, and 0.02° differential phase error are particularly useful when preserving waveform amplitude and timing relationships. The 400 V/µs slew rate supports large signal transitions, while 115 mA typical output current helps drive downstream back-termination or cable networks. Place the amplifier close to the source, use short feedback traces, and maintain a low-impedance ground reference to limit high-frequency errors.
Recomendado
Communications Signal Conditioning
Use the THS4061CD in communications front ends where analog signals must be amplified without excessive bandwidth loss or slow settling. The 180 MHz small-signal bandwidth, 400 V/µs slew rate, and 40 ns settling time to 0.1% provide a useful combination for intermediate-frequency, baseband, and high-speed control signals. Its stability at all gains supports both inverting and noninverting feedback arrangements. Designers should still account for communication-channel bandwidth, source impedance, termination, and board parasitics. Short, matched traces and a continuous ground plane are important when preserving high-frequency amplitude and phase performance.
Recomendado
Imaging and Sensor Signal Paths
The THS4061CD is appropriate for amplifying signals from imaging and sensor front ends where transient response affects image quality. Its 400 V/µs slew rate reduces the time required to traverse large output transitions, while the 40 ns settling specification helps the amplifier return quickly to its target level after a step. The 180 MHz bandwidth preserves high-frequency signal content that would be attenuated by slower general-purpose amplifiers. At the sensor interface, select feedback resistors for acceptable noise and bandwidth, minimize input-node capacitance, and keep the feedback loop compact to prevent unintended oscillation or peaking.
Recomendado
High-Speed Instrumentation
The THS4061CD can serve as a fast buffer or gain stage in instrumentation that must generate or measure rapidly changing waveforms. Its 180 MHz bandwidth accommodates substantially faster signals than conventional precision amplifiers, and the 115 mA typical output current provides drive for downstream scope inputs, active filters, or ADC drivers. The 40 ns settling time to 0.1% is valuable when the instrument must recover quickly between measurements. Use careful gain planning because gain and bandwidth are linked through the feedback network. Confirm output swing, load capacitance, and supply limits against the manufacturer electrical-characteristics table before finalizing the analog front end.
Recomendado
Active Filtering
The THS4061CD is well suited to active filters in which op-amp speed determines the achievable passband and stopband behavior. Its 180 MHz bandwidth provides headroom for filtering signals well above the frequencies commonly handled by precision op amps, while stability at all gain configurations simplifies common inverting and noninverting filter topologies. The 400 V/µs slew rate also reduces distortion for larger filter signals. Component tolerances and parasitic capacitance can materially affect high-frequency poles and peaking, so simulate the complete network. Keep feedback components close to the amplifier and provide a clean return path to reduce loop-area problems.
Recomendado
Industrial Control Signal Conditioning
The THS4061CD can condition fast control, sensor, and actuator signals in industrial systems where response time affects system accuracy. Its 400 V/µs slew rate, 180 MHz bandwidth, and 40 ns settling time allow the amplifier to follow rapid transitions with low distortion, while its typical 115 mA output current provides useful drive capability. The commercial 0°C to 70°C grade suits equipment expected to operate within that range. For industrial enclosure applications, verify the complete signal path for surge, ESD, temperature, and grounding requirements. Local bypass capacitors and short traces remain essential because long supply or signal paths can undermine the specified dynamic performance.

Notas de diseño
Keep the feedback loop physically small and connect the feedback components directly to the amplifier pins. High-speed voltage-feedback amplifiers can form an unintended oscillator when feedback-loop delay becomes comparable with the transit time around the loop. Use a continuous ground plane, short supply connections, and symmetrical input routing. If the source is remote or has substantial capacitance, place a series isolation resistor near the amplifier and evaluate its effect on bandwidth and gain.
Place the bypass capacitors at the supply pins and route them through short, low-inductance paths. The manufacturer lists 400 V/µs slew rate and 115 mA typical output current, so supply and ground connections must remain capable of supporting rapid output-current changes without introducing voltage steps into the signal. Confirm the absolute maximum and recommended supply conditions in the electrical-characteristics table before selecting rail voltage.
Do not assume that sharing the 8-SOIC outline guarantees drop-in compatibility. Verify pin numbers, NC pins, compensation or balance connections, supply pins, and maximum input and output voltage before substituting another amplifier. Gain stability must also be checked at the intended noise gain and load. For THS4031-family alternatives, the slew rate is approximately 12.5% lower than the THS4061CD, which can affect large-signal edge fidelity.
Treat the op amp, source, feedback network, and load as one high-frequency system. Input capacitance, PCB trace inductance, connector transitions, and unequal trace lengths can reduce effective bandwidth or introduce peaking even when the amplifier itself supports 180 MHz. Use short traces for high-frequency signals, minimize stubs, maintain consistent return paths, and evaluate the assembled board with time-domain or network measurements when waveform fidelity is critical.
