Product details
Overview
THS4001IDRG4 from Texas Instruments is a voltage-feedback high-speed operational amplifier optimized for professional video signal conditioning and wideband analog signal processing. It delivers 270 MHz bandwidth (G = 1, –3 dB), 400 V/µs slew rate, 40 ns settling time to 0.1%, ±2.5 V to ±15 V dual-supply operation, and 100 mA output drive-enabling precise amplification of composite video, RGB, or high-fidelity analog waveforms in broadcast equipment and test instrumentation.
For engineers reviewing the THS4001IDRG4 datasheet, THS4001IDRG4 pinout, THS4001IDRG4 application, or THS4001IDRG4 equivalent, key selection criteria include its stable unity-gain performance, differential gain/phase error (0.04%/0.15° at ±15 V), low distortion (–72 dBc THD at 1 MHz), and SOIC-8 package compatibility with high-frequency PCB layout requirements.
Technical Context
The THS4001IDRG4 employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, resulting in voltage-feedback architecture with inherently wide bandwidth and minimal phase margin trade-offs. Its internal compensation ensures stability across all closed-loop gains-including noninverting G = +1-without external components.
It supports both inverting and noninverting configurations with rail-to-rail input common-mode range (±13.5 V at ±15 V supply) and maintains 60 MHz 0.1-dB flatness for video fidelity. Output stage delivers ±10 V swing into 150 Ω while sourcing/sinking up to 100 mA, making it suitable for driving coaxial cables and active filters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 270 MHz at G = +1, ±15 V - enables full-spectrum amplification of HD video baseband signals without attenuation |
| Slew Rate | 400 V/µs - supports clean reproduction of fast transient edges in pulse and digital waveform applications |
| Settling Time (0.1%) | 40 ns for 10 V step - meets timing-critical requirements in high-speed data acquisition and DAC output buffering |
| Differential Gain / Phase | 0.04% / 0.15° at ±15 V - preserves color fidelity and sync integrity in SD/HD composite video systems |
| Total Harmonic Distortion | –72 dBc at f = 1 MHz - ensures low-noise signal integrity for precision analog front-ends and RF IF stages |
| Supply Voltage Range | ±2.5 V to ±15 V dual supply - allows flexible integration into legacy ±5 V, ±12 V, or modern low-voltage analog subsystems |
| Output Drive Current | ±100 mA - directly drives 75 Ω video lines or low-impedance ADC inputs without external buffers |
Pinout & Package
THS4001IDRG4 is housed in an 8-pin SOIC (D) package with 1.27 mm lead pitch, 3.9 mm body width, and 1.75 mm max height-designed for surface-mount assembly and high-frequency layout compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset null adjust | Connects to potentiometer wiper for fine-tuning input offset voltage; unused in standard configurations |
| 2 (IN–) | Inverting input | Primary feedback node; requires shortest possible trace to minimize parasitic capacitance and ringing |
| 3 (IN+) | Noninverting input | High-impedance signal input; must be routed away from noisy supply or output traces |
| 4 (VCC–) | Negative supply rail | Return path for internal biasing; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling |
| 5 (NULL) | No internal connection | Electrically isolated pad; no PCB connection required |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4031CD | Lower bandwidth (100 MHz), lower slew rate (100 V/µs), same SOIC-8 package and pinout | Targeted at cost-sensitive video applications where 60 MHz 0.1-dB flatness suffices | Select when full 270 MHz bandwidth is unnecessary and THD < –72 dBc is not required |
| THS4061ID | 180 MHz bandwidth, same 400 V/µs slew rate, higher input noise (14.5 nV/√Hz), same operating temperature range | Optimized for lower-power systems needing reduced quiescent current (6.7 mA at ±5 V) | Choose when balancing bandwidth, power, and noise for portable or thermally constrained designs |
Compared with THS4001IDRG4, THS4031CD trades bandwidth and slew rate for lower cost and power, while THS4061ID offers intermediate bandwidth with improved power efficiency but higher noise-making THS4001IDRG4 optimal for highest-fidelity video and fastest transient response.

FAQ
What is the operating temperature range for THS4001IDRG4?
The THS4001IDRG4 is rated for industrial operation from –40°C to +85°C, as confirmed by its "I" suffix designation and TI's official packaging documentation. This extended range supports deployment in outdoor broadcast enclosures, factory-floor test gear, and medical imaging systems exposed to ambient thermal variation. The device maintains specified bandwidth, slew rate, and distortion performance across this full range under recommended supply and loading conditions.
Does THS4001IDRG4 require external compensation for unity-gain stability?
No, THS4001IDRG4 is internally compensated for unity-gain stability in both inverting and noninverting configurations, eliminating the need for external compensation networks. Its design ensures ≥45° phase margin at G = +1, though application notes recommend a 200 Ω feedback resistor in noninverting unity-gain setups to minimize peaking and optimize settling behavior. This intrinsic stability simplifies schematic design and reduces layout sensitivity compared to decompensated high-speed op-amps.
Can THS4001IDRG4 drive a 75 Ω coaxial cable directly?
Yes, THS4001IDRG4 can drive a 75 Ω coaxial cable directly due to its ±100 mA output current capability and ability to deliver ±10 V swing into 150 Ω. For optimal impedance matching and suppression of reflections, TI recommends placing a 75 Ω series resistor at the amplifier output-this isolates capacitive load effects while establishing proper source termination. This configuration is validated in TI's application notes and evaluation board schematics for THS4001IDRG4.
What is the meaning of the "G4" suffix in THS4001IDRG4?
Per Texas Instruments' packaging nomenclature, the "G4" suffix in THS4001IDRG4 indicates RoHS-compliant lead finish using NiPdAu (nickel-palladium-gold) plating, replacing traditional lead-based finishes. It denotes conformance to environmental regulations without altering electrical specifications, thermal performance, or mechanical dimensions. The "R" denotes tape-and-reel packaging (2500 units per reel), and "ID" specifies the industrial temperature grade (–40°C to +85°C) in SOIC-8 package.
How does THS4001IDRG4 compare to THS4001ID in terms of specifications and use cases?
THS4001IDRG4 and THS4001ID share identical electrical specifications, thermal ratings, pinout, and functional behavior-the only difference is packaging: THS4001IDRG4 is supplied in tape-and-reel (2500/reel), while THS4001ID is in tube (75/unit). Both are industrial-grade (–40°C to +85°C), SOIC-8 devices with identical performance curves for bandwidth, slew rate, distortion, and video parameters. Selection depends solely on manufacturing assembly method-not circuit design or application suitability.
