Product details
Overview
THS3001IDGN from Texas Instruments is a high-speed current-feedback operational amplifier designed for precision video, imaging, and communication signal conditioning. It delivers 420MHz small-signal bandwidth (G = 1), 6500V/μs slew rate at ±15V supply, 40ns settling time (0.1%), and –96dBc THD at 1MHz - enabling ultra-fast ADC/DAC buffering and baseband signal amplification in high-fidelity analog front-ends.
For engineers reviewing the THS3001IDGN datasheet, THS3001IDGN pinout, THS3001IDGN application, or THS3001IDGN equivalent, this page provides verified electrical specifications, HVSSOP-8 package layout, real-world video/imaging use cases, and validated alternative options for high-bandwidth current-feedback amplifier selection.
Technical Context
The THS3001IDGN implements a dielectrically isolated complementary bipolar (HVBiCOM) current-feedback architecture with separate high-ft NPN/PNP transistors, enabling wide bandwidth independent of closed-loop gain configuration. Its transresistance-based feedback path allows stable operation with fixed RF values across gains, unlike voltage-feedback topologies.
It operates from dual supplies (±4.5V to ±16V) or single supply (9V to 32V), supports both inverting and noninverting configurations, and exhibits asymmetric slew behavior - faster negative slew (6500V/μs) than positive slew (6300V/μs) at ±15V - due to internal current-steering design and input node capacitance charging dynamics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 420MHz at G = 1, ±15V - enables full HD/3G-SDI video signal amplification without roll-off |
| Slew rate | 6500V/μs (negative), ±15V - supports >10Vpp fast transient signals in radar pulse conditioning |
| Settling time | 40ns to 0.1% - meets timing budget for 25Msps+ pipeline ADC drivers |
| THD | –96dBc at 1MHz, VO = 2Vpp - preserves SNR in wireless IF sampling receivers |
| Input offset | 3mV max - minimizes DC error in precision video DC restoration circuits |
| Supply range | ±4.5V to ±16V - compatible with industrial ±5V, ±12V, and telecom ±15V rails |
| Output drive | 100mA into 20Ω - drives 75Ω coaxial cables directly without external buffers |
Pinout & Package
HVSSOP-8 (DGN) package: 3mm × 4.9mm body, 0.5mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 | No connect | Internally unconnected; must be left floating or tied to ground per layout best practice |
| 2 | Inverting input | Current-summing node for feedback network; low impedance (~15Ω) requires matched trace routing |
| 3 | Noninverting input | High-impedance voltage reference point; sensitive to parasitic capacitance |
| 4 | Negative supply | Return path for bias currents; requires local 0.1μF + 4.7μF decoupling adjacent to pin |
| 6 | Amplifier output | Capable of ±12.8V swing into 1kΩ at ±15V; drives 150Ω loads with <0.1% distortion |
| 7 | Positive supply | Primary power rail; connects to VCC+ with low-inductance path to minimize supply-induced jitter |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Bandwidth remains stable across gain settings - simplifies design of programmable-gain video amplifiers |
| Low differential phase/gain | 0.02° / 0.01% at 115MHz - preserves color fidelity in broadcast-quality analog video paths |
| High output current | 100mA continuous - eliminates need for external emitter-follower stages in composite video drivers |
| Low input voltage noise | 1.6nV/√Hz at 10kHz - critical for low-level signal amplification in ultrasound receive chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Higher 2100MHz GBW, lower 1.1nV/√Hz noise, but only 200mA output drive and narrower supply range (±5V to ±15V) | Better for ultra-wideband IF amplification where noise dominates; less suitable for driving heavy capacitive loads | Select THS3091DR when bandwidth >1GHz and noise <1.2nV/√Hz are primary constraints |
| LMH6702MF/NOPB | Lower 1.55GHz GBW, higher 1200V/μs slew rate, wider supply (±2.5V to ±6V), no HVSSOP option (only SOIC-8) | Optimized for low-voltage portable instrumentation; lacks ±15V capability and video-grade differential phase specs | Select LMH6702MF/NOPB for battery-powered test equipment requiring sub-3V operation |
Compared with THS3001IDGN, THS3091DR offers superior bandwidth and noise but reduced output drive and supply flexibility, while LMH6702MF/NOPB trades bandwidth for low-voltage compatibility and lacks video-specific AC performance validation.

FAQ
What is the maximum operating temperature range for the THS3001IDGN?
The THS3001IDGN is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in video encoders, test equipment, and outdoor communications hardware. The device's junction temperature must remain below 125°C for continuous reliability, and its thermal resistance (RθJA) is 56.9°C/W in the HVSSOP-8 package - requiring appropriate PCB copper area and airflow for high-power applications. Always verify thermal design using actual load conditions and ambient environment for the THS3001IDGN.
Does the THS3001IDGN support single-supply operation?
Yes, the THS3001IDGN supports single-supply operation from 9V to 32V, in addition to dual-supply mode (±4.5V to ±16V). In single-supply configurations, the noninverting input must be biased within the common-mode input voltage range (e.g., VCC/2 for rail-to-rail output swing), and output swing is limited by headroom requirements. The datasheet specifies full performance at ±15V and ±5V, and single-supply validation is confirmed in TI's application notes for video line drivers. Designers must ensure proper decoupling and level-shifting networks when using the THS3001IDGN in single-supply systems.
What feedback resistor value is recommended for G = 2 in the THS3001IDGN?
For a gain of 2 with ±15V supplies, TI recommends RF = 680Ω for the THS3001IDGN - optimized for bandwidth, phase margin, and distortion trade-offs. At ±5V, the recommended value is 750Ω. These values are derived from empirical characterization and appear in Table 7-1 of the official datasheet. Using 1% tolerance metal-film resistors is required to maintain consistent frequency response; deviation beyond ±1% may cause peaking or bandwidth reduction. The THS3001IDGN's current-feedback architecture makes bandwidth highly sensitive to RF, not RG.
How does the THS3001IDGN compare to voltage-feedback amplifiers in video applications?
The THS3001IDGN outperforms most voltage-feedback amplifiers in video applications due to its current-feedback architecture: it achieves 115MHz 0.1dB bandwidth (vs. ~50MHz for typical VFB op-amps at G = 2), 0.01% differential gain, and 0.02° differential phase - meeting SMPTE 259M broadcast standards. Its constant bandwidth vs. gain eliminates re-tuning when adjusting video gain, and its 100mA output drive eliminates external buffers for 75Ω cable driving. Voltage-feedback alternatives require complex compensation and often fail to meet color fidelity specs at HD resolutions. This makes the THS3001IDGN uniquely suited among high-speed amplifiers for professional video signal paths.
Is an evaluation module available for the THS3001IDGN?
Yes, Texas Instruments offers the THS3001EVM evaluation module for the THS3001IDGN. It supports both inverting and noninverting configurations, includes SMA connectors for 50Ω signal I/O, on-board gain-setting resistors, and provisions for RF/RS tuning. The EVM enables rapid validation of bandwidth, distortion, and settling performance under real-world loading and supply conditions. TI provides full schematics, BOM, and test reports for the THS3001EVM, and Aetrix Electronics can supply the module alongside THS3001IDGN components for design-in acceleration.
