THS4041ID

THS4041ID - 165MHz High-Speed Op Amp | Texas Instruments

The Texas Instruments THS4041ID is a single, C-stable voltage-feedback operational amplifier with 165 MHz gain-bandwidth product, a 400 V/us slew rate, and an 8-pin SOIC package. It is designed for high-speed signal conditioning where wide bandwidth, fast edge rates, and stable operation with capacitive loads are important. The device operates as a general-purpose high-speed amplifier for video, test and measurement, communications, and analog-to-digital converter buffering. A voltage-feedback operational amplifier is a closed-loop amplifier whose feedback network sets the closed-loop gain while the amplifier corrects the difference between its input and feedback voltages. Compared with current-feedback amplifiers, the THS4041 family provides a familiar resistor-defined gain arrangement and remains stable at all supported gains in both inverting and noninverting configurations. This makes it suitable for designers who require conventional high-speed amplifier implementation without unusual gain-setting methods. The headline specifications are 165 MHz gain-bandwidth product, 400 V/us slew rate, and C-stable operation. Its bandwidth allows signals with substantial high-frequency content to pass with low closed-loop gain. The fast slew rate supports rapid output transitions, while the C-stable architecture permits driving capacitive loads, including cable capacitance and high-impedance converter inputs. The single-amplifier configuration also makes the THS4041ID suitable where one channel is sufficient and an additional package pin would add unnecessary complexity. Technical operation centers on a high-speed voltage-feedback amplifier core optimized for signal-path applications. The 8-pin SOIC package provides a conventional surface-mount assembly format and exposes the standard connections required for a single operational amplifier. Because the device is stable across all gains, the same amplifier can be used for unity-gain buffering, inverting signal conversion, and noninverting gain stages. When calculating closed-loop bandwidth, use the manufacturer gain-bandwidth relationship and apply additional margin where source impedance, capacitive loading, or feedback-layout effects matter. Typical uses include video-line driving, ADC input buffering, waveform conditioning, pulse shaping, communications-interface signal conditioning, and precision test equipment. In each case, the 165 MHz bandwidth can preserve fast transitions, while the 400 V/us slew rate helps the output follow demanding waveforms. For ADC interfaces, input capacitance and settling behavior should be checked together; for video cables, cable length and termination determine how much load the amplifier must drive. PCB implementation requires short feedback paths, controlled return-current geometry, and careful placement of bypass capacitance. Keep the feedback components close to the amplifier pins and provide a low-impedance ground return to limit parasitic feedback. When driving capacitive loads, use series isolation resistance if the system wiring creates overshoot or ringing, and validate the completed layout with oscilloscope measurements. This product page combines the manufacturer electrical characteristics with package guidance, application-focused design considerations, and a strict review of drop-in replacement options. The replacement section distinguishes genuine same-footprint choices from related or differently packaged parts so PCB changes are not mistaken for drop-in substitutions.

THS4052CD - 70MHz Dual High-Speed Op Amp | Texas Instruments

Texas Instruments THS4052CD is a dual-channel, 70 MHz voltage-feedback high-speed operational amplifier packaged in an 8-pin SOIC. Its key performance figures are 240 V/µs slew rate, 60 ns settling time to 0.1%, and typical output drive of 100 mA. The amplifier combines broad closed-loop bandwidth with low-cost operation for video, communications, imaging, and general-purpose signal-processing systems. 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.

The device is packaged in an 8-pin SOIC and provides typical output-drive current of 115 mA. It is intended for high-speed signal paths that require wide bandwidth, rapid transitions, and strong output-drive capability. 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.

THS4062CDR - 180MHz Dual High-Drive Op-Amp | Texas Instruments

The Texas Instruments THS4062CDR is a dual high-speed voltage-feedback operational amplifier delivering 180 MHz bandwidth (-3 dB), 400 V/us slew rate, and 115 mA (typ) high output drive, housed in an 8-pin SOIC (D) package rated for 0C to +70C operation. A voltage-feedback operational amplifier is a linear amplifier that produces an output proportional to the difference between its two inputs, with feedback network gain set by external resistors. Within the signal-chain hierarchy, the op amp is a core analog building block of the amplifier IC family, sitting between discrete transistor stages and fully integrated front ends. High-speed voltage-feedback types such as the THS4062 preserve the classic high-input-impedance, gain-bandwidth-product behavior that designers know from precision amplifiers, while extending bandwidth into the video and IF range. Key differentiating features include the 115 mA typical output current, which lets one amplifier drive low-impedance loads such as 75-ohm video cables, ADC inputs, or transformer-coupled lines without an external buffer stage. The 75 MHz 0.1 dB gain-flatness bandwidth and very low differential gain (0.02%) and differential phase (0.02 degrees) errors make it well suited to composite video signal paths. A 40 ns settling time to 0.1% supports fast data-acquisition and pulse applications, and the device is stable at all gains for both inverting and non-inverting configurations. Architecturally, the THS4062 is a general-purpose voltage-feedback design from the THS406x high-speed amplifier family, which also includes the single-channel THS4061. Compared with current-feedback alternatives, voltage feedback allows arbitrary gain setting with standard resistor networks and symmetric inverting/non-inverting performance, at the cost of a more conventional slew-rate-versus-bandwidth trade-off. Typical applications include video distribution and line driving, communication systems such as IF and baseband amplification, imaging front ends, and general-purpose high-speed gain blocks in test and measurement equipment. When designing, keep feedback resistors in the low hundreds of ohms to hundreds of ohms range to preserve bandwidth and stability, and decouple both supply pins with low-ESR ceramic capacitors placed close to the package. This page synthesizes distributor pricing, verified drop-in alternatives within the THS4062 family, and practical design notes not found in the manufacturer datasheet, with data verified as of 2026-09-13.

THS4062ID

THS4062ID - 180MHz Dual VFB Amplifier, 115mA | Texas Instruments

The Texas Instruments THS4062ID is a dual-channel high-speed voltage-feedback amplifier delivering 180 MHz bandwidth (-3 dB), a 400 V/us slew rate, and 115 mA (typ) of output drive current, housed in an 8-pin SOIC package. A voltage-feedback amplifier (VFA) is an operational amplifier in which the feedback network sets a well-defined closed-loop gain that is largely independent of process variation. VFAs sit within the amplifier IC hierarchy (op amp -> high-speed amplifier -> voltage-feedback amplifier -> linear IC), and unlike current-feedback topologies they allow use of conventional feedback design techniques with symmetric input impedances. Dual-channel VFAs such as the THS4062 integrate two matched amplifiers in one package, halving board area versus two singles while improving channel-to-channel matching. Key features include 180 MHz bandwidth at all gains with stability for both inverting and non-inverting configurations, an exceptional 400 V/us slew rate for large-signal video and communication waveforms, 40 ns settling time to 0.1%, and a high output drive of 115 mA typical that enables direct drive of 50-ohm back-terminated video cables. Video performance is a defining strength: 75 MHz 0.1 dB gain-flatness bandwidth, 0.02% differential gain and 0.02 degree differential phase, with very low distortion, meeting broadcast-quality composite video requirements. The supply range spans 4.5 V to 16 V (single or dual supplies), covering 5 V, +/-5 V and +/-12 V/+/-15 V rails. Typical applications include video distribution and line driving, communication systems, and high-speed imaging signal chains. Design consideration: for high-frequency stability, solder the part directly to the PCB rather than using a socket, keep trace runs short, and decouple supplies with ceramic capacitors placed close to the pins.

THS4062IDGNR

THS4062IDGNR - 180MHz Dual High-Speed Op-Amp | TI

The Texas Instruments THS4062IDGNR is a dual high-speed voltage-feedback operational amplifier delivering 180 MHz bandwidth (-3 dB), 400 V/us slew rate, and 115 mA (typ) output drive current per channel, housed in an 8-pin HVSSOP (DGN) package with exposed pad, rated from -40C to +85C on supplies from 9 V to 33 V (or +/-4.5 V to +/-16.5 V). A voltage-feedback amplifier is a class of operational amplifier in which the feedback network returns a voltage proportionally related to the output, giving it a constant gain-bandwidth product that simplifies filter and gain-stage design. Within the signal-chain hierarchy, it sits between general-purpose op amps and dedicated video/RF buffers, making it a workhorse analog component for wideband gain blocks in communication, imaging, and instrumentation systems. Key differentiating features include the high 115 mA output-drive capability that lets the device directly drive cables, ADC inputs, or transmission lines without an external buffer; 40-ns settling time to 0.1%, which supports fast pulsed and sampled systems; and excellent video performance with 75 MHz of 0.1 dB flatness bandwidth, 0.02% differential gain and 0.02-degree differential phase error. Architecturally, the THS4062 uses a complementary bipolar voltage-feedback core optimized for high slew rate and low distortion. Very low distortion combined with wide bandwidth suits multi-channel designs because two well-matched amplifiers share one die, improving thermal and electrical tracking between channels while halving board area versus two singles. Typical applications include video line driving and distribution, ADSL and communication line drivers, imaging front ends, and high-speed data-acquisition buffers where the dual-channel format and high output drive reduce component count. Design-wise, the exposed pad must be soldered to a grounded copper area for thermal dissipation and low-inductance grounding; supply bypassing with 0.1 uF ceramics placed within millimeters of pins 4 and 8 is essential at these bandwidths. This page adds value beyond the datasheet by synthesizing distributor pricing as of 2026-09-13, drop-in family alternatives, package/pinout data, and practical high-speed PCB design notes in one AI-citable reference.

The device is designed for communication and video signal paths where high bandwidth, fast settling, and low power consumption must coexist. Its quiescent current is 3.4 mA per channel, while its typical output-drive capability is 85 mA. A voltage-feedback operational amplifier is a closed-loop analog signal-conditioning device that uses feedback to control gain and linearity. The THS4081 belongs to the broader hierarchy of operational amplifiers, analog amplifiers, and integrated amplifier ICs. Its 175 MHz bandwidth supports high-frequency instrumentation, communications, video, and active-filter stages, while its low 3.4 mA quiescent current helps limit power consumption in space-constrained or portable systems. Key characteristics include 175 MHz bandwidth, 230 V/µs slew rate, and 43 ns settling time to 0.1%. The manufacturer also identifies excellent video performance with a 35 MHz bandwidth specification and differential gain of 0.05% at unity gain. These characteristics make the amplifier suitable for wideband buffers, gain stages, video signal conditioning, communications equipment, and active analog networks. The THS4081 uses voltage-feedback architecture, where the closed-loop bandwidth depends on the selected feedback network and noise gain. Its high slew rate permits large-amplitude signal transitions without excessive distortion, while the 43 ns settling specification supports high-data-rate decision and measurement circuits. The 85 mA typical output-drive capability provides useful load capability for downstream stages, although external buffering may still be needed for heavy capacitive or nonlinear loads. Typical uses include video amplifier chains, communications-interface signal conditioning, high-speed data-acquisition paths, active filters, and general-purpose high-frequency buffers. The low-power operating current is particularly valuable in portable test equipment, compact industrial systems, and communication modules where every milliamp affects battery life or thermal design. The single-amplifier configuration also keeps the 8-SOIC footprint compact compared with a dual-amplifier package. When designing around the THS4081ID, begin with the required gain, output swing, load impedance, and stability requirements rather than bandwidth alone. Feedback resistors determine gain and noise gain, while source and load capacitance can affect settling behavior. Confirm the operating supply range, input common-mode limits, output swing, and stability with the manufacturer datasheet before finalizing the circuit. This product page organizes the verified device characteristics, procurement path, and drop-in alternative information into one engineering reference. It also adds application-focused guidance for communication, video, instrumentation, filtering, portable equipment, and interface-buffer designs so that speed, power, drive capability, and board-area trade-offs can be evaluated together.

THS4082CD

THS4082CD - 175MHz Dual Voltage-Feedback Amplifier | Texas Instruments

Texas Instruments THS4082CD is a dual voltage-feedback operational amplifier with 175 MHz small-signal bandwidth, 230 V/us slew rate, and 3.4 mA quiescent current per channel. Designed for low-power operation, the device combines high-speed signal amplification with an 85 mA typical output-drive capability. It is supplied in an 8-pin SOIC (D) package for applications requiring two amplifiers in one package. An operational amplifier is an analog signal-conditioning semiconductor that uses high open-loop gain to amplify voltage differences between its inputs. The THS4082 belongs to the voltage-feedback amplifier family within the broader operational-amplifier, analog-IC, and semiconductor hierarchies. Unlike a current-feedback amplifier, a voltage-feedback amplifier generally uses feedback-network resistance and capacitance to establish gain and bandwidth, making it suitable for high-speed instrumentation and video signal paths. The main performance features include 175 MHz bandwidth, 230 V/us slew rate, 43 ns settling time to 0.1%, 85 mA typical output drive, and 35 MHz video bandwidth with 0.1 dB differential gain error and 0.05 degrees differential phase. Dual-channel architecture reduces package count and simplifies balanced or multi-stage signal conditioning. The dual voltage-feedback topology is particularly useful in communication and video equipment where accurate high-frequency amplification must coexist with low power consumption. The amplifier operates from a dual supply of up to plus or minus 16.5 V, corresponding to a total span of 33 V. Its wide bandwidth makes it capable of processing signals well beyond conventional audio frequencies, while the 3.4 mA per-channel quiescent current limits the power burden when both channels are active. The 85 mA output-drive specification also provides margin for driving downstream stages and PCB capacitance, although load current and stability still require careful evaluation. Typical uses include video processing, communication-signal conditioning, active filtering, test and measurement equipment, and general high-speed analog amplification. In a video path, one channel can amplify luminance or chroma information while the other handles a second signal. In instrumentation, the dual package can implement gain, filtering, or drive stages around higher-speed converters and sensors. The 35 MHz video bandwidth specification supports video-frequency signal chains requiring controlled gain and phase performance. Circuit design should preserve the amplifier's high-speed behavior by using a low-inductance ground plane, short feedback paths, and decoupling close to the supply pins. Resistor and capacitor selection around the feedback network directly affects gain accuracy and stability. Board-level parasitics, load capacitance, and output-current demand can influence overshoot and settling, so oscilloscope verification with the intended trace geometry is recommended. This product page combines the manufacturer's ordering information with a parameter-by-parameter comparison, drop-in replacement assessment, application guidance, and practical PCB design notes. It is intended to help engineers distinguish the THS4082CD from temperature-grade, packaging, and competing dual-amplifier options before committing a high-speed analog design to production.

According to the manufacturer product page, the device is specified for 0°C to 70°C operation and uses the SOIC (D) package with eight pins. It is designed for high-speed conversion and signal-conditioning systems requiring balanced analog signals. A fully differential amplifier is an amplifier whose input and output signals are represented by pairs of complementary voltages. It belongs to the operational-amplifier hierarchy, where it provides differential input, differential output, common-mode rejection, and balanced signal conversion. This topology helps downstream circuits reject common-mode interference and is particularly useful when driving analog-to-digital converters, converting single-ended sources into differential signals, and processing signals through balanced analog chains. The THS4141CD combines a 160 MHz -3 dB bandwidth with a high 450 V/us slew rate. The manufacturer also identifies a 6.5 nV/Hz input-referred noise specification and -79 dB third-harmonic distortion at 1 MHz. These characteristics support high-frequency signal fidelity when the device operates with the circuit conditions and supply voltages specified by the manufacturer. Its balanced outputs are designed to reject common-mode noise and preserve signal integrity across differential signal paths. The THS414x family uses a true fully differential signal path from input to output. This architecture avoids relying on an external subtractor to create the balanced output. A fully differential path can simplify ADC-interface layouts by keeping the input and output signal paths symmetrical and by reducing susceptibility to common-mode noise when correctly interfaced with the receiving circuit. Typical uses include high-speed differential ADC drivers, single-ended-to-differential conversion, differential antialiasing, and communications or instrumentation signal chains. The 160 MHz bandwidth and 450 V/us slew rate make it suitable for systems that need to preserve large-amplitude, rapidly changing waveform components rather than only low-frequency instrumentation signals. Circuit implementation should follow the manufacturer datasheet for supply decoupling, output balancing, gain configuration, and input common-mode limits. Because the device is a high-speed amplifier, short feedback traces, symmetric differential routing, careful grounding, and adequate bypass capacitance are important for maintaining high-frequency performance and limiting parasitic feedback. This page combines the manufacturer specifications with application guidance, comparison criteria, and design-focused information for engineers evaluating the THS4141CD. It also identifies the limitations that matter during replacement decisions, including temperature grade, package option, bandwidth, noise, slew rate, and fully differential pin compatibility.

THS4211D

THS4211D - 1 GHz High-Speed Operational Amplifier | TI

The Texas Instruments THS4211D is a high-speed, ultra-low-distortion voltage-feedback operational amplifier with 1 GHz bandwidth, 970 V/us slew rate, and a single-circuit 8-SOIC package. Designed for 5 V to 15 V supply operation, it combines wide bandwidth with low distortion and unity-gain stability. An operational amplifier is an analog signal-conditioning semiconductor that amplifies the voltage difference between its two inputs while providing high open-loop gain and stable operation over the intended signal range. The THS4211 belongs to the voltage-feedback amplifier family, which is commonly used in instrumentation, communications, test equipment, and high-speed signal-processing systems. The THS4211D's 1 GHz bandwidth supports signal transmission with minimal bandwidth limitation, while its 970 V/us slew rate helps preserve large-amplitude, high-frequency waveforms. Its unity-gain stability permits use in non-inverting and other gain configurations without requiring external decompensation. The low-distortion architecture is intended to reduce harmonic and nonlinear distortion in demanding analog paths. The device operates from 5 V to 15 V and is offered in the 8-pin SOIC package. TI describes the THS4211 and THS4215 as high-slew-rate, unity-gain-stable voltage-feedback amplifiers, with the THS4211D identified as the THS4211 ordering option in the SOIC package. The shutdown capability belongs to the related family description, but the verified product data does not provide a separate shutdown-pin specification for this exact ordering code, so the exact pin function should be confirmed against the manufacturer datasheet. Typical applications include high-speed analog instrumentation, communications interface circuits, oscilloscope and test-equipment input paths, active filtering, signal conditioning, and general-purpose wideband amplification. Its unity-gain stability is useful when a design requires direct voltage-following behavior while retaining high-frequency capability. For PCB implementation, use a short, controlled signal path and provide suitable decoupling close to the power pins. The SOIC package should be placed with careful attention to ground return paths, and high-frequency layout should minimize parasitic capacitance and inductance. Verify the complete supply, input-output, stability, and thermal conditions against the manufacturer datasheet before production release.

THS4215D

THS4215D - 1 GHz High-Speed Amplifier with Shutdown | Texas Instruments

The Texas Instruments THS4215D is a high-speed, ultra-low-distortion voltage feedback operational amplifier with shutdown, delivering 1 GHz small-signal bandwidth and a 970 V/us slew rate in an 8-pin SOIC (D) package. It is designed to run from supply voltages as low as 5 V and as high as 15 V, and it is unity-gain stable for direct buffering without external compensation. A voltage feedback operational amplifier is a closed-loop device whose inverting feedback network sets the closed-loop gain while the forward path is regulated to minimize distortion. The amplifier sits in the analog signal conditioning hierarchy: amplifier IC -> voltage feedback amplifier -> op amp -> analog signal conditioning integrated circuit. High-speed voltage feedback amplifiers are used wherever signals must be amplified with minimal magnitude and phase error at RF-like frequencies, such as ADC drivers, video paths, and active filters. Key differentiating features of the THS4215D include 1 GHz unity-gain bandwidth, a 970 V/us slew rate, ultra-low distortion, and a dedicated shutdown (power-down) control that lets the designer park the amplifier in a low-power state without removing it from the circuit. Because it is unity-gain stable, no external compensation network is required for gain-of-one buffering, and the same part can be used with resistive feedback for higher closed-loop gains. The combination of high slew rate, wide bandwidth, low distortion, and unity-gain stability is what makes the THS4211/THS4215 family a high-performance device across multiple AC specifications. The THS4215 offers the same performance as the THS4211 with the addition of power-down capability, making it the preferred member when system power management or channel muting is required. Because a 1 GHz bandwidth part is extremely sensitive to parasitic feedback, the device demands short, controlled routing and clean decoupling rather than simply a good schematic. Typical applications include high-speed ADC and DAC interface amplifiers, video and graphics signal chains, active filters, and test and measurement instrumentation front ends. In each case the part replaces a discrete or multi-stage amplifier chain with a single low-distortion, high-bandwidth device. When designing with the THS4215D, treat the PCB as part of the circuit: use very short feedback resistors, provide local high-frequency decoupling on both supply pins, and keep the shutdown control trace away from high-impedance input nodes. Confirm that the required closed-loop gain does not demand noise gain stability limits that the unity-gain stable architecture cannot support. This page consolidates manufacturer specifications, verified distributor pricing, drop-in replacement analysis, and practical design notes that are typically split across the datasheet, distributor listings, and application notes - helping engineers select, source, and implement the part with fewer iterations.

THS4221D

THS4221D - 230MHz High-Speed Rail-to-Rail Op Amp | Texas Instruments

The Texas Instruments THS4221D is a single, low-distortion, high-speed voltage-feedback operational amplifier with 230 MHz -3 dB bandwidth, 990 V/us slew rate, and rail-to-rail output swing, housed in an 8-pin SOIC package. Its stated supply range is ±1.35 V to ±7.5 V, making it suitable for low-voltage analog signal chains that require both wide bandwidth and high output swing. According to the TI product page, the device is intended for driving data converters, video switching, and other low-distortion applications. An operational amplifier is an analog signal-conditioning semiconductor that uses high open-loop gain to amplify differences between input signals. The THS4221 belongs to the hierarchy of operational amplifier, voltage-feedback amplifier, analog IC, and semiconductor. Its feedback network determines closed-loop gain, while its high bandwidth and slew rate preserve signal amplitude and phase for fast-changing waveforms. Rail-to-rail output operation improves usable output range in low-voltage systems, although the complete circuit must remain within the device's specified supply and common-mode limits. Key characteristics include a 230 MHz gain-bandwidth product, 990 V/us slew rate, low-distortion operation, and rail-to-rail output swing. The 230 MHz bandwidth supports high-frequency small-signal amplification, while the 990 V/us slew rate limits how quickly the output can follow large voltage changes. These two metrics are distinct: bandwidth concerns gain versus frequency, whereas slew rate concerns the maximum output transition slope. Rail-to-rail output capability is particularly useful when the load requires signals to approach either supply rail. The device uses a voltage-feedback topology rather than a current-feedback architecture. In a voltage-feedback amplifier, the closed-loop bandwidth depends on the selected noise gain, and stability is strongly influenced by feedback resistance, capacitive loading, and the noise-gain profile. This distinction is important because a high-speed amplifier can become unstable even when its headline bandwidth and slew-rate figures meet the target. Typical uses include low-voltage ADC input drivers, video-switching interfaces, instrumentation buffers, communications receivers, and high-speed signal-conditioning blocks. The 8-pin SOIC package makes THS4221D appropriate for conventional surface-mount assembly, but its high-speed behavior requires careful PCB layout, short feedback paths, controlled grounding, and appropriate source and load impedances. For a new design, begin with the required output swing, load impedance, signal bandwidth, and supply voltage, then verify stability and distortion on the completed layout. Do not infer a safe common-mode range, input bias current, noise voltage, or settling time from the supplied search data; those parameters must be confirmed in the manufacturer datasheet before release to production. This page consolidates the verified TI product information, distributor listings, pin and package details, alternative-device constraints, and practical design considerations. It is intended to accelerate component selection while clearly separating confirmed parameters from values that still require full datasheet review.

THS4222D

THS4222D - Dual 120MHz Rail-to-Rail Op Amp | Texas Instruments

The Texas Instruments THS4222D is a dual, low-voltage, rail-to-rail output operational amplifier designed for high-speed, low-distortion signal conditioning. Each channel uses voltage-feedback architecture and operates from a single 3 V supply up to a single 15 V supply. The device provides 120 MHz gain-bandwidth performance and 990 V/us slew rate, making it suitable for driving data converters, video-switching circuits, and other wideband analog signal chains. The THS4222 family belongs to the operational-amplifier category, which sits within analog signal-chain and semiconductor devices. An operational amplifier provides high open-loop gain and uses negative feedback to amplify or condition a differential signal. The rail-to-rail output stage allows the output voltage to swing close to the positive and negative supply rails, improving output utilization in low-voltage systems while retaining useful high-speed performance. Key features include dual-circuit configuration, rail-to-rail output operation, 120 MHz bandwidth, and 990 V/us slew rate. The family is specifically intended for applications requiring low distortion and high output swing, including analog-to-digital converter input drivers, video switching, and general high-speed amplifier stages. According to the verified manufacturer product description, the family can operate from a single 15 V supply down to a single 3 V supply. The THS4222D uses a voltage-feedback topology rather than a current-feedback topology. This architecture is commonly selected when straightforward resistor-defined gain, predictable feedback implementation, and general-purpose high-speed signal conditioning are required. Its dual-channel arrangement allows two related signal paths to share one package, reducing board area when the two channels do not need fully independent power management. Typical applications include ADC input amplification, video-buffer and video-switching circuits, active filtering, test and measurement signal paths, and low-distortion analog front ends. The 3 V minimum supply supports compact portable and embedded systems, while the 15 V maximum family supply provides flexibility for higher-voltage analog rails. Designers should verify input and output common-mode limits, output-load conditions, feedback values, and stability requirements against the manufacturer datasheet before layout release. When placing the device, keep feedback traces short and symmetrical, provide a solid ground reference, and route high-speed outputs away from sensitive input nodes. Decoupling capacitors should be placed close to the supply pins. Because this is a high-speed amplifier, PCB parasitics, capacitive loading, trace impedance, and connector or via transitions can materially affect gain, bandwidth, and distortion. This page consolidates verified manufacturer and distributor information with engineering-oriented selection guidance and application notes. This synthesis emphasizes verified product identity, package information, supply capability, bandwidth, slew rate, and practical circuit considerations rather than inferring undocumented specifications. For a production design, use the official TI datasheet and current distributor inventory as the controlling sources for electrical limits, test conditions, pin functions, lifecycle status, and commercial availability.

THS4223D

THS4223D - 230MHz Rail-to-Rail Op Amp | Texas Instruments

Texas Instruments THS4223D is a low-distortion, high-speed differential operational amplifier with a 230 MHz gain-bandwidth product and rail-to-rail output swing, supplied in a 14-pin SOIC package. It operates from a 1.35 V to 7.5 V supply and is specified over a -40 °C to +85 °C industrial temperature range. The device combines two amplifier circuits with differential operation, making it suitable for low-voltage analog-to-digital converter front ends, instrumentation, signal conditioning, and other wideband analog systems. An operational amplifier is a voltage-gain building block that compares an input signal with a feedback network. A differential amplifier uses the voltage difference between two inputs, allowing common-mode noise and interference to be rejected when the system detects or processes a small signal riding on a larger common-mode voltage. In the broader semiconductor hierarchy, the THS4223D belongs to the operational-amplifier, analog-amplifier, signal-conditioning, and integrated-circuit classes. The principal verified features of the THS4223D include a 230 MHz high-speed rating, rail-to-rail output swing, a 1.35 V to 7.5 V supply-voltage range, and low-distortion operation. These characteristics make the amplifier relevant to applications requiring wider bandwidth and lower output distortion than general-purpose op amps. Rail-to-rail output operation also improves usable output range in low-voltage systems where conventional amplifier outputs lose headroom near the supply rails. The 14-SOIC package provides a compact surface-mount implementation with a 1.27 mm terminal pitch. A 14-pin package offers a practical footprint for differential analog layouts because signal, power, feedback, and bypass connections can be grouped around the device. The industrial temperature grade supports equipment expected to operate across the stated -40 °C to +85 °C range, although designers should still verify system-level heat rise and worst-case operating conditions. Typical uses include low-voltage ADC input drivers, communications receivers, measurement front ends, and high-speed feedback networks. In an ADC driver, the amplifier can provide gain, impedance conversion, and differential signal conditioning before conversion. In receiver circuits, differential operation can reduce common-mode pickup when the source is balanced and the PCB provides symmetric routing. A critical design practice is to preserve the amplifier's high-speed behavior with short feedback traces, symmetric differential routing, adequate input/output bypassing, and a ground reference capable of supporting high-frequency current. Decoupling capacitance, resistor values, and the selected feedback network should follow the manufacturer's guidance because unsupported values cannot be inferred from the available search data. This product record combines the verified distributor and manufacturer-page information with explicit data gaps, practical layout guidance, sourcing details, and a selection framework. It distinguishes confirmed THS4223D attributes from parameters that still require confirmation from the full manufacturer datasheet, helping engineers avoid treating incomplete distributor snippets as complete design specifications.

It accepts supply voltages from ±1.35 V to ±7.5 V according to the distributor specification supplied for this device. The combination of high bandwidth, fast slew rate, and rail-to-rail output swing targets low-voltage data-converter drive, video switching, and other low-distortion signal-chain applications. A high-speed operational amplifier is a voltage-feedback amplifier designed to amplify signals while preserving amplitude accuracy and phase relationships across a wide frequency range. In the signal-chain hierarchy, an operational amplifier is an analog integrated circuit, while THS4225D belongs to the specialized high-speed, low-distortion amplifier class. Its rail-to-rail output stage can approach the supply rails, providing additional output swing in low-voltage systems where usable output range is limited. The principal verified performance figures are a 230 MHz -3 dB bandwidth, a 975 V/µs slew rate, and a rail-to-rail output. The bandwidth determines the useful small-signal frequency range, while slew rate constrains how quickly the output can move under large-signal conditions. These two limits must be considered together when driving capacitive loads, routing through long PCB traces, or processing large transient signals. The THS4225 is positioned as a single amplifier, while the related THS4226 provides a dual configuration. Typical applications include low-voltage analog-to-digital converter inputs, video switching circuits, low-distortion signal conditioning, communications equipment, and instrumentation. Its 8-pin SOIC package is also compatible with conventional surface-mount assembly methods, although careful attention to grounding and decoupling remains important. Designers should place power-supply bypass capacitors close to the device and use short, low-inductance feedback routes. Stability and usable output swing also depend on load capacitance, gain, supply voltage, and PCB construction. The available verified material does not provide a complete pin table, detailed noise values, input offset voltage, input bias current, or current pricing, so those parameters must be confirmed from the manufacturer documentation before final design release. This product page combines the verified manufacturer identity, package information, distributor descriptions, technical search excerpts, and application-specific engineering guidance. It also distinguishes confirmed data from parameters that still require direct confirmation, helping engineers evaluate THS4225D without converting missing specifications into unsupported assumptions.

THS4227D

THS4227D - Dual 120MHz Rail-to-Rail Op Amp | Texas Instruments

The Texas Instruments THS4227D is a dual, low-distortion, high-speed, rail-to-rail output operational amplifier with a 1.35 V to 7.5 V supply-voltage range and 120 MHz gain-bandwidth performance. It is supplied in a 14-pin SOIC package and is intended for low-voltage signal-conditioning, data-conversion, and communications applications. According to the verified product listings, the device provides approximately 900 nA of input bias current, 990 V/us slew rate, and operation from -40 C to +85 C. An operational amplifier is an analog building block that amplifies the difference between two input voltages while providing high input impedance and low output impedance. The THS4227D belongs to the voltage-feedback operational-amplifier family within the broader linear-IC and signal-processing hierarchy. Its rail-to-rail output capability allows the output voltage to approach the supply rails more closely than a conventional fixed-output amplifier, which is useful in compact, low-voltage systems. The main performance features are 120 MHz bandwidth, 990 V/us slew rate, approximately 900 nA input bias current, and a 1.35 V to 7.5 V operating supply range. These specifications make the amplifier suitable for applications requiring rapid transitions, wide-band signal amplification, or low-voltage ADC-driver support. The dual configuration provides two amplifiers in one package, reducing board area when two channels are required. The THS4227D uses a voltage-feedback architecture and is specified for low-voltage analog-to-digital converter interfacing, among other precision signal paths. The combination of high bandwidth and rail-to-rail output can preserve signal swing in systems where the available supply headroom is limited. Designers should nevertheless verify output-current capability, settling behavior, output-voltage limits, input common-mode range, stability, and noise values against the manufacturer datasheet before finalizing a design. Typical applications include low-voltage ADC input drivers, video and communications signal conditioning, instrumentation interfaces, and portable or industrial control systems. In each case, the amplifier can be used where a dual, high-speed voltage-feedback stage is needed without moving to a larger or more power-intensive package. The SOIC-16 package designation appears in one verified datasheet index, while distributor listings also identify the device as a 14-SOIC; the exact mechanical drawing should therefore be confirmed from the manufacturer documentation. A key design consideration is to keep the feedback network short and use appropriate source and load impedances for the required closed-loop gain. High-speed voltage-feedback amplifiers can be sensitive to parasitic capacitance, excessive loop gain, and improperly placed compensation components. The supply rails should be decoupled close to the device, and the output must remain within the datasheet-defined operating limits. This page consolidates verified distributor pricing, package information, operating limits, and drop-in alternative research for engineers comparing the THS4227D with other dual high-speed operational amplifiers. Because the supplied cross-reference results identify replacement manufacturers but do not name specific substitute MPNs, no unsupported part numbers are presented as drop-in alternatives.

THS4271D

THS4271D - 400MHz High-Speed Amplifier | Texas Instruments

The Texas Instruments THS4271D is a single, unity-gain-stable voltage-feedback operational amplifier with 400 MHz gain-bandwidth product, 1000 V/us slew rate, and low-noise, low-distortion performance in an 8-pin SOIC package. It is designed to operate from 5 V to 10 V total supply voltage, supporting single-supply and positive/negative-rail systems. The combination of wide bandwidth, high slew rate, and unity-gain stability makes it suitable for high-linearity ADC preamplification, wireless receiver signal chains, DAC output buffering, and differential-to-single-ended conversion. The THS4271D is also identified as a super-fast, ultra-low-distortion high-speed amplifier, with a voltage-feedback architecture intended to provide higher dynamic range across a wider frequency band than decompensated alternatives. A voltage-feedback operational amplifier is an analog amplifier whose feedback network sets the closed-loop gain while preserving stability at unity gain. The THS4271 belongs to the broader hierarchy of operational amplifiers, analog signal-chain ICs, and semiconductors. Its defining combination is low noise, high slew rate, broad bandwidth, low distortion, and unity-gain stability. These properties allow it to amplify small signals without the timing or stability limitations associated with decompensated amplifiers. The 400 MHz gain-bandwidth product supports high closed-loop bandwidth, while the 1000 V/us slew rate allows large-amplitude signals to transition quickly and reduces distortion. Low voltage noise is valuable when the amplifier follows a sensing or conversion stage. Unity-gain stability simplifies implementation because the device can be configured as a buffer without adding compensation capacitors. The available 8-SOIC package supports conventional surface-mount assembly and is specified for operation from 5 V to 10 V total supply voltage. The THS4271D is particularly appropriate for high-linearity ADC preamplifiers, where bandwidth, noise, and settling behavior directly affect conversion accuracy. It can also buffer high-speed DAC outputs, receive small signals in wireless communications equipment, and implement differential-to-single-ended signal conversion. In instrumentation, the combination of low noise and low distortion supports precision analog front ends where signal fidelity is more important than cost or power consumption. Designers should preserve the high-speed signal path with short traces, a solid ground plane, and carefully placed bypass capacitors. Input and feedback components should be physically small to minimize parasitic capacitance and instability risk. Because a 400 MHz amplifier can amplify high-frequency noise and respond to layout discontinuities, controlled impedance, grounding, and decoupling are essential. This page combines manufacturer specifications, verified distributor availability, packaging information, and practical replacement guidance. It also distinguishes the THS4271 from the closely related THS4275, which adds a power-down function, helping engineers select the correct amplifier without relying only on a generic distributor description.

The THS4275 family combines wide bandwidth, low noise, high slew rate, and low distortion, making it suitable for instrumentation, signal conditioning, data acquisition, and communications applications where accurate amplification of rapidly changing signals is required. An operational amplifier is an active semiconductor device that uses high-gain differential amplification to increase the amplitude of an input signal. A voltage-feedback amplifier routes its output through a feedback network, while the THS4275D provides the combination of unity-gain stability and wide bandwidth needed for precision signal conditioning. Its performance characteristics are intended to support low-noise and low-distortion operation across multiple AC specifications. The THS4275D is a single amplifier rather than a dual or quad device, allowing designers to use independent gain paths when channel count, routing, or power-management requirements favor discrete single-channel sections. The verified manufacturer information identifies the THS4275 as a super-fast, ultra-low-distortion high-speed amplifier with shutdown capability. The shutdown function can reduce power consumption when the signal path is not active, subject to the device's specified operating conditions. The 8-SOIC package provides a conventional surface-mount footprint for laboratory, industrial, instrumentation, and communications equipment. Because the supplied verified data does not include the complete electrical tables, pin assignments, noise density, slew rate, distortion figures, supply-current limits, or exact input and output headroom, those parameters are not guessed here. The 400 MHz bandwidth, -40°C to +85°C temperature range, SOIC package, and shutdown-enabled product description are the verified attributes available for comparison. Typical applications include high-speed signal conditioning, communications receive and transmit paths, instrumentation front ends, test and measurement equipment, and analog signal chains requiring low distortion. The unity-gain-stable architecture also allows use as a general-purpose high-speed amplifier when the circuit is designed around the manufacturer's recommended operating conditions. Designers should preserve adequate input and output voltage headroom, maintain the recommended bypassing near the supply pins, and verify shutdown-control polarity and timing against the manufacturer datasheet before production release. This page combines verified manufacturer and distributor information, structured application guidance, parameter comparison, and practical sourcing details for engineers evaluating the THS4275D.

THS4281D

THS4281D - 90MHz, 35V/us Low-Power RRIO Op Amp | Texas Instruments

The Texas Instruments THS4281D is a single, very-low-power, high-speed, rail-to-rail input/output voltage-feedback operational amplifier with a 90 MHz unity-gain bandwidth, 35 V/us slew rate, and 8-pin SOIC package. It operates from 2.7 V to 15 V on a single supply or from plus/minus 1.35 V to plus/minus 7.5 V on a dual supply. An operational amplifier is an analog signal-conditioning semiconductor that compares two inputs and drives its output according to external feedback. The THS4281 belongs to the hierarchy of voltage-feedback amplifier, operational amplifier, analog IC, and semiconductor. Its rail-to-rail input stage accepts signals close to the supply rails, while its rail-to-rail output stage provides useful output swing near either rail. The BiCom-II process supports a combination of speed and low power. Verified device data identifies a 90 MHz unity-gain bandwidth, 35 V/us slew rate, and typical 750 uA quiescent current at 5 V. These characteristics make the amplifier suitable for portable instrumentation, low-power signal conditioning, active filtering, buffer stages, and high-speed analog systems where bandwidth matters more than nanoamp-level bias current. The wide supply range allows operation from 3.3 V and 5 V systems, as well as higher-voltage analog rails up to the verified 15 V maximum single-supply limit. Rail-to-rail input and output behavior increases usable signal range in low-voltage designs, although output-headroom, loading, common-mode range, stability, and noise still require verification for the selected gain and supply condition. Typical uses include portable test equipment, sensor signal conditioning, active filters, small-signal transducers, and low-power analog interfaces. Because it is a voltage-feedback device, feedback-network values and parasitic capacitance strongly influence bandwidth and stability. Designers should use short, low-inductance feedback paths and follow the manufacturer's recommended operating and layout guidance. A key design trade-off is speed versus power: the THS4281D provides substantially more bandwidth than general-purpose low-power amplifiers while consuming 750 uA at 5 V, but it is not automatically the best choice where microamp or picoamp input bias, very low offset voltage, or ultra-low-noise operation dominates. This product record combines verified manufacturer specifications, package information, sourcing references, application guidance, and replacement qualification limits. Alternative parts are listed only when same-package, pin-compatible evidence is available; otherwise missing qualification data is disclosed rather than inferred.

A wideband operational amplifier is a voltage-feedback amplifier designed to amplify signals over a much broader frequency range than conventional precision op amps. Its place in the signal-chain hierarchy is between general-purpose amplifiers and specialized high-speed RF components: it provides gain, buffering, filtering, and impedance conversion while operating from a single supply. The THS4304 is therefore suited to analog front ends where signal bandwidth, supply simplicity, and low-noise performance are more important than rail-to-rail input or output operation. The verified manufacturer description identifies the THS4304 as a 3 GHz low-noise wideband operational amplifier. Its voltage-feedback architecture is appropriate for closed-loop gains defined by external resistors, while the single 5 V supply simplifies system power compared with traditional plus-and-minus 5 V analog designs. The device is manufactured in the BiCom3 silicon-germanium process, a process technology specifically cited by Texas Instruments for this amplifier family. Typical uses include high-speed instrumentation, communication receivers, analog filters, data-acquisition front ends, and signal-conditioning chains. The amplifier can be used where a compact single-supply solution must process high-frequency signals without adopting a more complex multi-rail power architecture. Its wide bandwidth makes feedback and stability layout particularly important; resistor values, parasitic capacitance, grounding, and supply decoupling must be controlled close to the device pins. The 8-pin SOIC package is a surface-mount package in the SOIC family. Designers should consult the manufacturer datasheet for the complete pinout, electrical characteristics, recommended application circuits, stability requirements, and absolute maximum ratings. Because the available verified results do not expose every numeric electrical specification, values not explicitly present in the supplied data are marked as [DATA_NEEDED] rather than inferred. This page consolidates the verified Texas Instruments product identity, manufacturer datasheet link, distributor product records, package information, and cross-reference search results. It also distinguishes the THS4304D orderable 8-pin SOIC variant from related device names and avoids presenting unverified substitute parts as drop-in replacements.

The THS4503ID supports operation from a wide 15 V power-supply range. The THS4503 is optimized for systems requiring both high speed and high linearity. Its -95 dBc IMD3 at 30 MHz helps reduce distortion in multicarrier receiver paths, while its 370 MHz bandwidth provides ample bandwidth for high-resolution ADC front ends. The 2800 V/us slew rate supports large-signal transitions without narrowing the useful signal bandwidth. Unlike the related THS4502, the THS4503 does not include power-down capability, which simplifies control for designs that do not need a shutdown input. Typical applications include high-linearity ADC preamplifiers, wireless communication receiver chains, differential signal-conditioning stages, high-speed instrumentation, and balanced input buffers. The device is especially relevant where a 14-bit conversion system must preserve signal integrity through the analog input stage. Designers should account for input and output bandwidth, common-mode range, supply headroom, and ADC settling requirements when selecting external resistors and compensation networks. For a new design, begin with the manufacturer’s THS4503 typical application circuit and preserve short, symmetric differential traces. Keep the feedback network compact and matched, and provide local bypassing close to the supply pins. Confirm that the selected ADC, cable, connector, and sampling system preserve the differential signal through 40 MHz and across the intended output amplitude. This product page consolidates the manufacturer specifications, package details, functional alternatives, comparison parameters, and practical PCB guidance for the THS4503ID.

A shutdown function helps reduce power consumption when the signal chain is inactive. The fully differential architecture provides balanced outputs and an output common-mode control function, making THS4504D suitable for driving high-speed analog-to-digital converters through resistive networks or transformer interfaces. Its bandwidth and distortion performance support 12-bit operation through 40 MHz according to the Texas Instruments product-page description. Designers should still verify signal settling, output swing, common-mode range, and external-component requirements against the manufacturer datasheet for the exact operating conditions. Typical applications include high-speed data acquisition, communications receivers, differential analog front ends, and instrumentation chains. In these systems, the amplifier can suppress common-mode noise, maintain differential balance, and provide the slew rate needed for rapidly changing waveforms. The shutdown feature is useful in portable, test-and-measurement, and power-sequenced systems where continuous operation is unnecessary. A critical design consideration is preserving differential symmetry. Input and output component networks should use matched layouts and values, the output common-mode voltage must remain within the valid range, and the PCB should minimize parasitic capacitance between differential nodes. Stable power-supply decoupling and careful grounding are necessary to prevent supply noise or board asymmetry from degrading distortion performance. This page combines the verified manufacturer and distributor information for THS4504D with practical application guidance, specification comparisons, and drop-in-replacement analysis. The supplied cross-reference search did not establish five distinct pin-compatible alternatives, so the engineering analysis avoids presenting unverified substitutes as drop-in parts.

In the signal-chain hierarchy, the THS4505D belongs to the operational-amplifier and analog-amplifier family, specifically the fully differential amplifier category used to preserve differential signal integrity. Its differential architecture helps reduce common-mode interference and is especially useful when the source and destination both operate with differential signaling. Key performance features include 260 MHz small-signal bandwidth and an 1800 V/µs slew rate. The 260 MHz bandwidth is suitable for high-speed instrumentation and communication paths, while the high slew rate supports rapid transitions through larger voltage swings. The device is specified for 15 V total power supply, including support for the negative power-supply rail. According to the verified TI product information, the THS4504 and THS4505 family supports 12-bit operation through 40 MHz, and the THS4505 is the version without power-down capability. The THS4505D uses a fully differential architecture with output common-mode control. This is important in systems where the differential output must be biased correctly for an ADC, DAC, transceiver, or downstream differential receiver. The low-distortion characteristics make the device useful where signal fidelity is more important than simply amplifying a low-frequency sensor signal. Its 8-pin SOIC package also supports conventional surface-mount assembly and board-level prototype development. Typical applications include differential ADC and DAC interface circuits, communication receivers and transmitters, test and measurement instruments, high-speed data-acquisition systems, and analog signal-conditioning modules. The 260 MHz bandwidth and 1800 V/µs slew rate provide useful performance margin for signals extending into the tens of megahertz, while the -73 dBc IMD3 and 29 dBm OIP3 figures indicate strong linearity for demanding RF and IF signal paths. When designing a circuit around the THS4505D, verify the external resistor and capacitor values required by the selected gain and output common-mode configuration, and confirm that the downstream device accepts the resulting differential swing. Provide adequate supply decoupling close to the power pins and maintain the specified common-mode and output-voltage operating limits. The THS4505D is the non-power-down member of the family; designs requiring a dedicated shutdown function should evaluate the THS4504 family instead.
