THS4052CD - 70MHz Dual High-Speed Op Amp | Texas Instruments
部品番号: THS4052CD ✓ 生産中THS4052CD 概要
A voltage-feedback operational amplifier is an analog amplifier that uses feedback to control gain and bandwidth. It belongs to the operational amplifier hierarchy, which includes precision, high-speed, and power operational amplifiers before expanding into analog signal-processing integrated circuits. Voltage-feedback topology is especially useful when an application requires adjustable gain, straightforward feedback compensation, and operation across both inverting and non-inverting configurations.
The THS4052 provides 70 MHz gain-bandwidth performance, a 240 V/µs slew rate, and 60 ns settling time to within 0.1%. Its output can source or sink a typical 100 mA, making it suitable for driving moderate capacitive and resistive loads. Video performance includes 0.1 dB bandwidth of 30 MHz, differential gain error of 0.01%, and differential phase of 0.01 degree. These characteristics support video amplification, line driving, communications, and imaging tasks where bandwidth and signal fidelity both matter.
The device uses a voltage-feedback architecture and is stable at all gains for both inverting and non-inverting configurations, according to the manufacturer product page. That operating range gives designers flexibility when changing signal gain around a fixed PCB. As a dual amplifier, it can implement two independent channels or a differential signal-conditioning stage, reducing the number of signal-chain packages required in multichannel systems.
Typical applications include composite and component video buffers, communications-interface signal conditioning, imaging circuits, video measurement systems, and general high-speed analog signal chains. The 8-pin SOIC package also simplifies laboratory prototyping and allows direct substitution with compatible SOIC-8 dual amplifiers after checking offset, bandwidth, slew rate, supply range, and input-output swing.
PCB design should minimize feedback-loop length, keep input and output paths away from switching nodes, and provide local supply bypassing close to the power pins. Avoid driving large capacitive loads directly unless the output-drive and stability behavior has been evaluated. Because this amplifier is optimized for speed rather than micropower operation, thermal and supply-current requirements should be included in system power budgeting.
This page combines the manufacturer specifications, ordering information, source links, application guidance, and verified substitution analysis to support faster component selection and PCB planning. It also distinguishes genuine pin-compatible choices from package-only matches so engineers can assess replacement risk before changing a released design.

主な用途
THS4052CD の用途: 6 件s: Composite Video Signal Conditioning, Communications Front-End Amplification, Imaging and Sensor Signal Chains, Video Distribution and Gain Control, Test and Measurement Front Ends, General High-Speed Analog Processing.
Composite Video Signal Conditioning
The THS4052CD fits composite video buffers because its 70 MHz gain-bandwidth product preserves signal bandwidth while its 240 V/µs slew rate supports rapid transitions through cables and termination networks. The 0.1 dB differential bandwidth of 30 MHz helps maintain amplitude balance, while the specified 0.01% differential gain and 0.01° differential phase minimize channel-to-channel distortion. Two amplifiers are available in the package for separate synchronization or control paths. Place the device close to the source, terminate the line according to the video standard, and keep feedback components away from high-speed output routing.
おすすめ
Communications Front-End Amplification
The THS4052CD is appropriate for communications blocks that require more bandwidth than general-purpose op amps can provide. Its 70 MHz closed-loop bandwidth supports signal amplification above the baseband region, and its 60 ns settling time to 0.1% helps preserve timing when the output drives a sampling or conversion stage. The dual configuration can condition two related channels or provide gain in an inverting and non-inverting path. The 100 mA typical output drive gives adequate authority for moderate loading, but cable losses, input capacitance, and downstream loading must be checked before the amplifier is placed at a board edge.
おすすめ
Imaging and Sensor Signal Chains
The THS4052CD can amplify outputs from imaging sensors because its 70 MHz bandwidth handles fast sensor waveforms and its 240 V/µs slew rate reduces transition distortion. These characteristics are especially relevant when a sensor produces narrow pulses, burst-mode analog data, or multiplexed video-like signals. The two channels can serve adjacent sensor outputs or implement differential gain, allowing common circuitry to be shared. Care is required around the sensor output range because the input common-mode limits are not established in the available product summary. Confirm signal amplitude, offset, noise, and sensor drive requirements against the manufacturer datasheet before finalizing the interface.
おすすめ
Video Distribution and Gain Control
The THS4052CD works well in compact video distribution circuits because it combines 70 MHz bandwidth, high slew rate, and two amplifiers in one 8-pin SOIC. One channel can amplify a component signal while the other provides buffering for sync or control, reducing board area compared with two separate single amplifiers. Low differential gain and phase figures support accurate signal reproduction in multi-format systems. The design should use short feedback paths, preserve the recommended operating region, and account for the amplifier’s output-current capability when driving cable capacitance or termination networks.
おすすめ
Test and Measurement Front Ends
The THS4052CD is useful as a high-speed front end in compact measurement equipment because it settles to 0.1% in 60 ns and provides a 70 MHz gain-bandwidth product. These characteristics help preserve pulse shape and amplitude when a sensor, probe, or test fixture produces rapidly changing signals. The dual amplifier can support complementary outputs, channel gain calibration, or a differential measurement arrangement. Layout must minimize parasitic capacitance at the inputs, use symmetric feedback networks where channel matching matters, and maintain short paths from the source to the amplifier. Confirm input offset and noise behavior for the required measurement resolution.
おすすめ
General High-Speed Analog Processing
The THS4052CD can serve as a general high-speed analog building block for pulse, edge, and small-signal conditioning applications. Its 70 MHz bandwidth supports moderate-frequency closed-loop gains, while the 240 V/µs slew rate limits large-signal edge distortion. Because both inverting and non-inverting configurations are stable at all gains, feedback design can be adapted to inversion, scaling, and buffering requirements. Stable operation does not eliminate the need to check noise gain, output swing, load impedance, and power dissipation. Place bypass capacitors near the supply pins and keep high-impedance input nodes short to reduce pickup and parasitic feedback.

設計ノート
Keep the feedback loop physically small and connect feedback resistors directly to the relevant input and output pins. The THS4052 has 70 MHz bandwidth and 240 V/µs slew rate, so even short PCB traces can introduce phase error at upper operating frequencies. Place input components away from output and supply-routing nodes, and use a solid ground plane to minimize parasitic coupling.
Place the supply-bypass capacitor close to the positive and negative power pins and use a short, low-inductance return path. The available product information identifies a typical output-drive capability of 100 mA but does not state supply voltage or quiescent current, so those values must be confirmed before sizing the regulator and estimating dissipation. Avoid adding series resistance in either supply connection.
Do not assume that an SOIC-8 package alone establishes drop-in compatibility. Verify the complete pinout, supply range, input common-mode range, output swing, stability, and load behavior for THS4052IDR or THS4052CDR. These are ordering variants of the same TI family, but any alternate amplifier from another manufacturer still requires a full electrical and timing review.
Keep video, communications, and imaging traces short and reference a continuous ground plane. Route input nets before output nets where practical, maintain symmetry between differential channels, and avoid passing high-speed output traces beneath sensitive input components. The 0.1 dB bandwidth of 30 MHz and 0.01° differential phase are meaningful only when PCB parasitics and terminations are controlled.
