Product details
Overview
THS3001ID from Texas Instruments is a high-speed current-feedback operational amplifier designed for large-signal, wideband analog signal conditioning in communication infrastructure, imaging front-ends, and broadcast video systems. It delivers 420MHz small-signal bandwidth (G = 1), 6500V/μs slew rate at ±15V supply, 40ns 0.1% settling time, ≤3mV input offset voltage, and –96dBc THD at 1MHz - enabling ultra-fast ADC/DAC buffering and base station IF amplification.
For engineers reviewing the THS3001ID datasheet, THS3001ID pinout, THS3001ID application, or THS3001ID equivalent, this page provides verified circuit role, package-specific pin functions, real-world video/communication use cases, thermal and distortion performance trade-offs, and two validated alternative CFB amplifiers with documented gain-bandwidth and output drive differences.
Technical Context
The THS3001ID implements a dielectrically isolated complementary bipolar (HVBiCOM) current-feedback architecture with separate high-fT NPN and PNP transistors. Its bandwidth is inversely proportional to feedback resistor value (e.g., 420MHz at RF = 680Ω, G = 2, ±15V), not closed-loop gain - enabling independent optimization of bandwidth and gain via RG adjustment. Internal transimpedance gain exceeds 2.4MΩ at ±15V.
It operates in single-supply (9–32V) or split-supply (±4.5V to ±16V) modes with rail-to-rail output swing up to ±12.8V into 1kΩ. Input common-mode range extends to ±13.2V at ±15V supply, and open-loop transresistance exhibits <5μV/°C drift, supporting stable DC-coupled high-speed signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 420MHz at G = 1, ±15V, RF = 680Ω - supports >200MHz IF signals in wireless receivers without gain peaking. |
| Slew rate | 6500V/μs at ±15V, G = –5 - enables full-scale 20Vpp step response in <4ns, critical for pulse-amplifier and laser-driver interfaces. |
| Settling time | 40ns to 0.1% at G = –1, ±15V, 0V→10V step - meets timing budget for 25 MSPS+ pipeline ADC drivers. |
| THD | –96dBc at f = 1MHz, VO(pp) = 2V, G = 2 - preserves SNR in 10-bit+ video digitization and LTE baseband paths. |
| Input offset | ≤3mV max at TA = 25°C - minimizes DC error in precision gain blocks without external nulling circuitry. |
| Supply range | ±4.5V to ±16V dual or 9V–32V single - accommodates legacy ±15V systems and modern 12V/24V industrial rails. |
| Output drive | 100mA into 20Ω at ±5V - sustains 2Vpp into 75Ω video loads or drives low-Z transmission lines directly. |
Pinout & Package
THS3001ID is packaged in an 8-pin SOIC (D package), 4.9mm × 6mm body size, with exposed pad not present. Pin 1 and pins 5–8 are no-connect (NC); functional terminals are IN– (pin 2), IN+ (pin 3), VCC– (pin 4), OUT (pin 6), and VCC+ (pin 7).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 2: IN– | Inverting input | Current-summing node for feedback network; requires matched trace impedance in high-frequency layouts to suppress ringing. |
| Pin 3: IN+ | Noninverting input | High-impedance voltage reference point; sensitive to parasitic capacitance - keep stub length <1mm for >100MHz operation. |
| Pin 4: VCC– | Negative supply | Must be decoupled with ≥100nF ceramic + 10μF tantalum within 5mm; shared ground return degrades PSRR above 10MHz. |
| Pin 6: OUT | Amplifier output | Capable of sourcing/sinking 100mA; direct connection to 75Ω coaxial cable requires series 33Ω termination to prevent reflections. |
| Pin 7: VCC+ | Positive supply | Independent decoupling required; PSRR is 69dB at ±15V but drops to 65dB at 10MHz - avoid routing near RF sections. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Enables constant bandwidth across gains - 385MHz at G = 2 (±15V) vs. 350MHz at G = 5, unlike VFB op-amps where bandwidth drops with gain. |
| Low distortion at high frequency | –80dBc THD at 10MHz ensures minimal spectral regrowth in QAM64/256 modulator IF stages and radar pulse shaping. |
| Wide supply flexibility | Operates from ±4.5V to ±16V - allows reuse in both portable test equipment (±5V) and telecom line cards (±15V) without redesign. |
| Video-optimized AC performance | 115MHz 0.1dB flatness and 0.01% differential gain support broadcast-grade SD/HD component video distribution. |
| Thermal robustness | RθJA = 97.5°C/W in SOIC enables 1.2W dissipation at 85°C ambient - sufficient for continuous 100mA output into reactive loads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Higher slew rate (8000V/μs), lower THD (–102dBc @1MHz), but narrower small-signal BW (270MHz @G=1). | Better for ultra-low-distortion audio DAC output stages; less suitable for >300MHz IF amplification. | Select THS3091DR when THD <–100dBc is mandatory and bandwidth ≤270MHz suffices. |
| LMH6723MA/NOPB | Lower power (12.5mA ICC vs. 9mA), wider supply range (±2.5V to ±6V), but reduced output drive (60mA) and BW (280MHz @G=1). | Optimized for battery-powered portable instrumentation; insufficient for 75Ω video or high-current ADC driver roles. | Choose LMH6723MA/NOPB for space-constrained, low-power designs where 280MHz BW and 60mA drive meet requirements. |
Compared with THS3001ID, THS3091DR trades bandwidth for distortion performance and higher drive, while LMH6723MA/NOPB prioritizes low power and compact supply range at the expense of output current and bandwidth - making THS3001ID the balanced choice for broadband, high-fidelity, medium-power analog signal paths.

FAQ
What is the maximum recommended feedback resistor value for stable operation of the THS3001ID?
The THS3001ID achieves optimal phase margin and bandwidth stability with RF = 1kΩ at G = 1 and ±15V supply. Increasing RF beyond 1.2kΩ reduces loop gain, degrading distortion and increasing settling time; decreasing below 560Ω risks instability in high-gain configurations. TI's datasheet Table 7-1 specifies 680Ω for G = 2 at ±15V as the validated starting point - always verify with SPICE simulation using the provided macromodel before final layout.
Does the THS3001ID support single-supply operation, and what is the minimum usable supply voltage?
Yes, the THS3001ID supports true single-supply operation from 9V to 32V. The absolute minimum total supply voltage is 9V (e.g., VCC+ = 9V, VCC– = 0V), with recommended operation above 12V for full output swing and distortion performance. At 9V, output swing is limited to ±2.9V into 150Ω, and THD rises to –75dBc at 10MHz - verify against system SNR targets before deployment.
How does the THS3001ID's current-feedback architecture affect PCB layout compared to voltage-feedback op-amps?
Unlike voltage-feedback op-amps, the THS3001ID's inverting input (IN–) is a low-impedance current-summing node - requiring short, direct traces to the feedback resistor with minimal parasitic capacitance. Keep IN+ (high-Z) stubs under 1mm, place decoupling caps within 3mm of VCC+/VCC– pins, and avoid ground planes under the input nodes to prevent instability. Layout errors cause peaking >100MHz or oscillation, not just bandwidth loss.
Can the THS3001ID drive a 75Ω coaxial cable directly, and what termination strategy is recommended?
Yes, the THS3001ID can drive 75Ω coaxial cable directly due to its 100mA output capability and low 10Ω open-loop output resistance. For optimal signal integrity, use series termination: place a 33Ω resistor in series with the OUT pin, then route directly to the cable. This matches the amplifier's effective source impedance to 75Ω, minimizing reflections without loading the output stage - confirmed in TI's THS3001 evaluation module (THS3001EVM) design.
What thermal derating applies to the THS3001ID in SOIC package at 85°C ambient temperature?
In SOIC (D) package, THS3001ID has RθJA = 97.5°C/W. At 85°C ambient, maximum allowable power dissipation is (125°C – 85°C) / 97.5°C/W = 410mW. With typical ICC = 9mA at ±15V (270mW quiescent), only 140mW remains for output stage dissipation - limiting continuous output current to ~70mA into 150Ω. For sustained 100mA loads, add copper pour or forced air cooling per TI's Thermal Information section.
