Product details
Overview
THS3001CDRG4 from Texas Instruments is a high-speed current-feedback operational amplifier designed for large-signal, wideband analog signal conditioning in communication infrastructure and video systems. It delivers 420MHz small-signal bandwidth (G = 1), 6500V/μs slew rate at ±15V supply, 40ns settling time to 0.1%, ≤3mV input offset voltage, and –96dBc THD at 1MHz - enabling ultra-fast ADC/DAC buffering and base station IF amplification.
For engineers reviewing the THS3001CDRG4 datasheet, THS3001CDRG4 pinout, THS3001CDRG4 application, or THS3001CDRG4 equivalent, this page provides verified electrical specifications, SOIC-8 pin mapping, real-world video/communication use cases, and validated alternative options - all grounded in TI's SLOS217I production datasheet (December 2024 revision).
Technical Context
The THS3001CDRG4 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 = 1kΩ, G = 1), not gain-setting resistor - enabling independent optimization of bandwidth and closed-loop gain.
It operates from dual supplies of ±4.5V to ±16V (or single 9V–32V), supports inverting/noninverting configurations, and exhibits asymmetric slew behavior: inverting mode achieves higher slew rates due to virtual-ground input nodes reducing capacitive charging delay. Input bias currents are 1–10μA (typ), with 1.6nV/√Hz input voltage noise and 13/16pA/√Hz input current noise (noninverting/inverting).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (–3dB) | 420MHz at G = 1, ±15V supply - enables direct IF amplification up to UHF without intermediate filtering |
| Slew rate | 6500V/μs at ±15V, G = –5 - supports clean 20VPP output steps in <10ns for pulse/RF applications |
| Settling time (0.1%) | 40ns for 10V step at ±15V - meets timing-critical sampling requirements in high-speed data acquisition |
| THD | –96dBc at f = 1MHz, VO = 2VPP, G = 2 - preserves signal fidelity in wireless base station transmit chains |
| Input offset voltage | ≤3mV (max) at 25°C - minimizes DC error in precision video gain stages and sensor front-ends |
| Supply range | ±4.5V to ±16V dual or 9V–32V single - accommodates legacy ±15V systems and modern low-voltage designs |
| Output drive | 100mA into 20Ω at ±5V - drives 75Ω video lines or low-Z ADC inputs without external buffers |
Pinout & Package
THS3001CDRG4 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 Figure 4-1 and Table 4-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | NC | No internal connection - must be left floating; no PCB trace or thermal pad required |
| 2 | IN– | Inverting input - connects to feedback network; sensitive to parasitic capacitance affecting stability |
| 3 | IN+ | Noninverting input - high-impedance node; requires matched layout to IN– for common-mode rejection |
| 4 | VCC– | Negative power-supply rail - decoupling capacitor (0.1μF ceramic + 4.7μF tantalum) required within 5mm |
| 6 | OUT | Amplifier output - capable of ±12.8V swing into 1kΩ at ±15V; drives 150Ω loads directly |
| 7 | VCC+ | Positive power-supply rail - same decoupling requirement as VCC–; shared ground plane critical |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Enables bandwidth independence from closed-loop gain - allows fixed RF = 1kΩ for stable 420MHz response while adjusting RG for gain tuning |
| Low distortion at high frequency | –80dBc THD at 10MHz ensures minimal spectral regrowth in broadband communications and digital video interfaces |
| Video-optimized AC performance | 115MHz 0.1dB flatness (G = 2) with 0.01% differential gain/0.02° phase error meets SMPTE 253M broadcast standards |
| High output current | 100mA continuous drive into low-Z loads eliminates need for external buffer stages in composite video or cable driver designs |
| Wide supply flexibility | Operates from ±4.5V to ±16V - supports both industrial ±12V systems and telecom ±15V rails without redesign |

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 690MHz bandwidth but lower 100mA output drive; uses 8-pin VSSOP (DGN) package only | Better suited for >500MHz IF stages where load current ≤50mA; not drop-in compatible due to different footprint | Select THS3091DR when bandwidth >450MHz is mandatory and board layout allows HVSSOP-8 rework |
| THS3095D | Same SOIC-8 package; lower 300MHz bandwidth but improved –102dBc THD at 1MHz and 2.5mV max VIO | Preferred for ultra-low-distortion audio or precision instrumentation where bandwidth ≤300MHz suffices | Choose THS3095D when THD < –98dBc is required and 420MHz bandwidth is excessive for the signal chain |
Compared with THS3001CDRG4, THS3091DR trades SOIC-8 compatibility for higher bandwidth in a smaller HVSSOP package, while THS3095D retains the same SOIC-8 footprint but prioritizes distortion and offset over speed - making each a purpose-fit alternative rather than a generic substitute.

FAQ
What is the maximum operating supply voltage for THS3001CDRG4?
The THS3001CDRG4 supports dual-supply operation from ±4.5V to ±16V (32V total) or single-supply from 9V to 32V. Absolute maximum ratings specify ±16.5V on VCC+ and VCC–, but recommended operation is limited to ±16V to ensure long-term reliability and specified performance across temperature. Exceeding ±16V risks permanent damage per TI SLOS217I Section 5.1.
Does THS3001CDRG4 support single-supply operation?
Yes, THS3001CDRG4 supports true single-supply operation from 9V to 32V. The input common-mode range extends to within 3.2V of VCC– (ground in single-supply mode), and output can swing to within 3.2V of either rail. For optimal performance, TI recommends using a split-rail configuration with bypass capacitors on both VCC+ and VCC– pins, even in single-supply setups.
What is the recommended feedback resistor for THS3001CDRG4 at G = 2?
TI specifies 680Ω for ±15V supplies and 750Ω for ±5V supplies when configuring THS3001CDRG4 for G = 2. These values balance bandwidth, phase margin, and distortion - yielding 385MHz (±15V) or 300MHz (±5V) small-signal bandwidth. Using 1% tolerance resistors is mandatory; deviation beyond ±1% degrades stability and frequency response predictability.
How does THS3001CDRG4 compare to voltage-feedback amplifiers in bandwidth scalability?
Unlike voltage-feedback amplifiers, THS3001CDRG4 bandwidth depends primarily on feedback resistor value (RF), not closed-loop gain. This allows maintaining 420MHz bandwidth at G = 1 while increasing gain via the gain resistor (RG) - a key advantage for multi-gain systems where bandwidth consistency is critical. Voltage-feedback parts would sacrifice bandwidth proportionally with gain increase.
Is THS3001CDRG4 suitable for driving 75Ω video loads?
Yes, THS3001CDRG4 delivers 100mA output current and ±12.8V swing into 1kΩ at ±15V, enabling direct 75Ω drive with proper termination. Its 115MHz 0.1dB bandwidth, 0.01% differential gain, and 0.02° differential phase meet SMPTE 253M broadcast video standards - confirmed in TI SLOS217I Section 1 and Figure 5-22.
