Product details
Overview
THS3001IDG4 from Texas Instruments is a high-speed current-feedback operational amplifier optimized for large-signal transient response in video, imaging, and communication systems. It delivers 420MHz small-signal bandwidth (G = 1), 6500V/μs slew rate (±15V supply), 40ns 0.1% settling time, and –96dBc THD at 1MHz - enabling ultra-fast ADC/DAC buffering and base station signal conditioning.
For engineers reviewing the THS3001IDG4 datasheet, THS3001IDG4 pinout, THS3001IDG4 application, or THS3001IDG4 equivalent, key selection criteria include its current-feedback architecture's gain-independent bandwidth control, ±4.5V to ±16V dual-supply operation, low 3mV max input offset voltage, and SOIC-8 package compatibility with high-density PCB layouts.
Technical Context
The THS3001IDG4 uses a dielectrically isolated complementary bipolar (HVBiCOM) process with GHz fT transistors, enabling true current-feedback topology where bandwidth is set primarily by feedback resistor value-not gain-allowing independent optimization of speed and gain. Its transresistance-based internal architecture yields high open-loop transimpedance (2.4MΩ at ±15V) and low input impedance at the inverting node (15Ω).
This architecture supports stable operation across ±4.5V to ±16V supplies and enables fast settling without peaking in unity-gain buffer or inverting amplifier configurations. Input common-mode range extends to ±13.2V at ±15V supply, and output swing reaches ±12.8V into 1kΩ, making it suitable for wide-dynamic-range analog signal paths requiring minimal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 420MHz at G = 1, ±15V - enables direct RF IF-stage amplification up to UHF without external equalization |
| Slew rate | 6500V/μs at ±15V - supports clean 20VPP output steps in <40ns, critical for high-fidelity video line drivers |
| THD | –96dBc at 1MHz, 2VPP, G = 2 - ensures <0.0015% harmonic distortion in broadcast-quality video reconstruction |
| Input offset | 3mV max at 25°C - maintains DC accuracy in precision gain stages without trimming in industrial imaging front-ends |
| Supply range | ±4.5V to ±16V - allows flexible integration into legacy ±5V, ±12V, or modern ±15V analog subsystems |
| Output drive | 100mA into 20Ω at ±5V - drives coaxial cables or multiple downstream loads without external buffers |
| Settling time | 40ns to 0.1% at G = –1, ±15V - meets timing budgets for 25Msps+ pipeline ADC drivers |
Pinout & Package
THS3001IDG4 is packaged in an 8-pin SOIC (D package), 4.9mm × 6mm body size, with exposed pad not present. Pin functions are validated per TI SLOS217I Rev. December 2024.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No connect (NC) | Internally unconnected; must remain floating or grounded per layout best practices to minimize parasitic coupling |
| 2 | Inverting input (IN–) | Low-impedance current-summing node (15Ω); sets closed-loop gain with external RG; sensitive to PCB trace capacitance |
| 3 | Noninverting input (IN+) | High-impedance voltage reference node (1.5MΩ); used for biasing or noninverting configuration; requires guarded routing |
| 4 | Negative supply (VCC–) | Return path for internal bias currents; requires low-ESR local decoupling (e.g., 100nF X7R + 10μF tantalum) |
| 6 | Amplifier output (OUT) | Capable of ±12.8V swing into 1kΩ; drives 150Ω video loads directly; layout demands short, wide traces to minimize inductance |
| 7 | Positive supply (VCC+) | Primary power rail; supplies output stage quiescent current (6.6–9mA typical); shares decoupling with VCC– |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Bandwidth remains stable across gain settings via independent RF/RG selection - eliminates trade-off between speed and gain in VFB op-amps |
| Ultra-low distortion | –96dBc THD at 1MHz enables use in LTE/5G baseband I/Q modulator chains without spectral regrowth |
| High output current | 100mA drive capability supports direct termination of 75Ω video lines or parallel loading of multiple ADC inputs |
| Wide supply range | ±4.5V to ±16V operation allows reuse across ±5V instrumentation, ±12V industrial PLCs, and ±15V test equipment |
| Video-optimized AC performance | 115MHz 0.1dB flatness (G = 2) and 0.01% differential gain ensure broadcast-grade NTSC/PAL signal fidelity |

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 320MHz bandwidth and higher 10.5mA quiescent current | Better suited for ultra-low-distortion DAC output stages where bandwidth ≤300MHz suffices | Select THS3091DR when THD < –100dBc is mandatory and power budget allows +35% IQ |
| LMH6723MA/NOPB | Lower 2.2mV max VOS, wider 1.8GHz bandwidth (G = 2), but only 3000V/μs slew rate and limited ±6V supply range | Ideal for high-gain, wideband photodiode transimpedance amps where DC accuracy and GHz bandwidth outweigh slew needs | Choose LMH6723MA/NOPB for G ≥ 5 applications demanding >1GHz closed-loop bandwidth and <2.5mV offset |
Compared with THS3001IDG4, THS3091DR trades bandwidth for superior distortion performance and higher power, while LMH6723MA/NOPB offers extreme bandwidth and offset precision at the cost of slew rate and supply flexibility - making THS3001IDG4 the balanced choice for video, ADC driving, and baseband reconstruction where 420MHz BW, 6500V/μs SR, and ±16V operation are jointly required.

FAQ
What is the maximum recommended feedback resistor value for stable operation of the THS3001IDG4?
The THS3001IDG4 achieves optimal stability and bandwidth with a 1kΩ feedback resistor (RF) at G = 1. Increasing RF reduces bandwidth and phase margin; values above 1.5kΩ risk peaking or oscillation. TI's datasheet specifies 1kΩ as the standard recommendation for balanced performance across supply voltages and gains, and this value is validated in all production test conditions for THS3001IDG4.
Does the THS3001IDG4 support single-supply operation, and what is the minimum usable supply voltage?
Yes, the THS3001IDG4 supports single-supply operation with a minimum total supply voltage of 9V (e.g., 0V to +9V). The device operates across 9V to 32V single-supply or ±4.5V to ±16V split-supply ranges. At 9V, output swing is reduced (±2.9V into 150Ω), but all key specs including 330MHz bandwidth and 1700V/μs slew rate remain functional - confirmed in TI SLOS217I Section 5.3.
How does the THS3001IDG4's current-feedback architecture affect gain-setting resistor selection?
In the THS3001IDG4, gain is set by the resistor from IN+ to ground (RG), while bandwidth is controlled by the feedback resistor (RF). This decoupling allows independent optimization: e.g., fixing RF = 1kΩ for 420MHz BW, then adjusting RG to change gain from 1 to 10 without altering bandwidth. This behavior is intrinsic to THS3001IDG4's current-feedback topology and differs fundamentally from voltage-feedback op-amps.
What thermal derating applies to the THS3001IDG4 in SOIC-8 package at elevated ambient temperatures?
The THS3001IDG4 in SOIC-8 (D package) has RθJA = 97.5°C/W. At TA = 70°C and ±15V supply, quiescent power dissipation is ~135mW; junction temperature rises ~13°C above ambient, well below the 125°C continuous-reliability limit. Derating begins above 85°C ambient - TI specifies maximum operating TA = 85°C, and thermal shutdown is not integrated, so external thermal monitoring is advised for sustained high-power operation.
Can the THS3001IDG4 be used in inverting configuration with gain magnitude greater than 5, and what are the stability considerations?
Yes, the THS3001IDG4 supports inverting gains up to |G| = 10 using appropriate RF/RG values (e.g., RF = 560Ω, RG = 56Ω for G = –10 at ±15V). Stability is maintained by adhering to TI's recommended RF values in Table 7-1; deviations increase risk of ringing. Layout must minimize parasitic capacitance at IN–, as excess capacitance degrades phase margin - a known design constraint explicitly documented for THS3001IDG4.
