Product details
Overview
THS4011IDGNR from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier optimized for precision video and wideband signal conditioning. It delivers 290-MHz bandwidth (G = 1, –3 dB), 310-V/µs slew rate, and 37-ns 0.1% settling time while operating on ±4.5 V to ±16 V supplies - enabling use in analog front-ends for broadcast-quality video reconstruction and high-fidelity data acquisition systems.
For engineers reviewing the THS4011IDGNR datasheet, THS4011IDGNR pinout, THS4011IDGNR application, or THS4011IDGNR equivalent, key selection criteria include its 7.5-nV/√Hz input voltage noise, –80 dBc THD at 1 MHz, 0.006% differential gain error, and MSOP PowerPAD™ package thermal performance - all critical for low-distortion, high-resolution signal chain design.
Technical Context
The THS4011IDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wide bandwidth and fast transient response without sacrificing DC precision. Its voltage-feedback architecture supports stable unity-gain operation with internal compensation tuned for minimal peaking in noninverting configurations.
It features rail-to-rail output swing capability (±13.5 V into 1 kΩ at ±15 V supply), 110-mA output drive, and integrated offset nulling terminals (pins 1 and 8) - allowing fine-tuning of input offset voltage in high-accuracy applications where drift must be minimized across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1: supports full-spectrum baseband video (e.g., HD-SDI reconstruction) without attenuation. |
| Slew Rate | 310 V/µs: enables faithful reproduction of fast-edged signals up to ~50 MHz without slewing distortion. |
| THD | –80 dBc at 1 MHz, RL = 150 Ω: ensures minimal harmonic contamination in RF sampling and instrumentation amplification. |
| Differential Gain Error | 0.006% at NTSC, ±15 V: preserves color fidelity in professional video distribution and broadcast equipment. |
| Input Voltage Noise | 7.5 nV/√Hz at 10 kHz: maintains SNR integrity when amplifying µV-level sensor outputs or low-level IF signals. |
| Supply Range | ±4.5 V to ±16 V (dual) or +9 V to +32 V (single): accommodates legacy industrial rails and modern high-voltage analog systems. |
| Quiescent Current | 7.8 mA per channel at ±15 V: balances speed and power efficiency for thermally constrained PCB layouts. |
Pinout & Package
THS4011IDGNR uses an 8-pin MSOP PowerPAD™ (DGN) package with exposed thermal pad on underside. The PowerPAD enhances thermal dissipation (θJA = 58.4°C/W), supporting continuous operation at elevated ambient temperatures without derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null | Connects to potentiometer wiper for manual input offset voltage trimming; referenced to VCC−. |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance (2 MΩ), low-input-bias-current path for feedback network connection. |
| 3 | Noninverting Input (IN+) | Differential input node; matched to IN− for common-mode rejection (CMRR = 82 dB typical). |
| 4 | VCC− | Negative supply rail; must be decoupled with 0.1 µF ceramic capacitor placed ≤0.1 inch from pin. |
| 5 | NC | No internal connection; electrically isolated - no routing or grounding required. |
| 6 | Output (OUT) | Capable of ±13.5 V swing into 1 kΩ; drives 110 mA continuously; requires series resistor ≥20 Ω for >10 pF capacitive loads. |
| 7 | VCC+ | Positive supply rail; decoupling identical to VCC−; supports split or single-supply operation. |
| 8 | Offset Null | Connects to potentiometer end; referenced to VCC−; used with Pin 1 to form adjustable nulling network. |
Key Features
| Feature | Design Value |
|---|---|
| 290-MHz Unity-Gain Bandwidth | Enables direct amplification of composite video, ADC/DAC interface buffers, and IF stages without external compensation. |
| 0.006% Differential Gain Error | Preserves chrominance amplitude accuracy in SD/HD video transmission, meeting SMPTE 259M compliance thresholds. |
| PowerPAD™ Thermal Enhancement | Reduces junction-to-ambient thermal resistance by >65% vs. standard MSOP, enabling 2.14 W power dissipation at TA = 25°C. |
| Offset Nulling Terminals | Allows sub-100 µV residual offset calibration - essential for DC-coupled imaging chains and precision test equipment. |
| 70-MHz 0.1-dB Bandwidth | Ensures flat group delay and minimal phase distortion across entire NTSC/PAL luminance spectrum (0–5.5 MHz). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4011IDR | Same silicon, SOIC-8 (D) package; θJA = 167°C/W vs. 58.4°C/W for DGN; no thermal pad. | Limited to lower-power operation (<740 mW) and ambient temperatures ≤70°C without heatsinking. | Select THS4011IDR only if board space allows SOIC footprint and thermal budget permits higher junction rise. |
| LMH6702MA/NOPB | 320-MHz bandwidth, 1000-V/µs slew rate, but higher 9.5-nV/√Hz noise and no offset null pins. | Better suited for ultra-fast pulse amplification than precision video; lacks differential gain/phase specs. | Choose LMH6702MA/NOPB when speed dominates over video fidelity and DC trim capability. |
Compared with THS4011IDGNR, THS4011IDR trades thermal performance for legacy package compatibility, while LMH6702MA/NOPB prioritizes raw speed over low-distortion video metrics - making THS4011IDGNR uniquely balanced for high-fidelity, thermally demanding analog signal paths.

FAQ
What is the maximum safe supply voltage for THS4011IDGNR?
The absolute maximum supply voltage for THS4011IDGNR is ±16.5 V (dual) or +33 V (single). Operation beyond these limits risks permanent damage to the internal bipolar transistors. Recommended operating range is ±4.5 V to ±16 V for dual supply or +9 V to +32 V for single supply, per TI SLOS216E datasheet Section 6.1.
Does THS4011IDGNR support single-supply operation?
Yes, THS4011IDGNR supports true single-supply operation from +9 V to +32 V. Its input common-mode range extends to within 1.5 V of VCC− (ground), and output swings to within 1.5 V of either rail - enabling use in ground-referenced signal chains such as CCD drivers and sensor interfaces without level-shifting circuitry.
How is the PowerPAD™ thermal pad on THS4011IDGNR electrically isolated?
The PowerPAD™ thermal pad on THS4011IDGNR is electrically isolated from all internal circuitry and pins. TI confirms this in the SLOS216E datasheet Figure 33 note: "The thermal pad is electrically isolated from all terminals in the package." It may be connected directly to PCB ground or a dedicated thermal plane without risk of shorting.
Can THS4011IDGNR drive a 75-Ω coaxial cable directly?
Yes - THS4011IDGNR can drive 75-Ω cables when configured with a 75-Ω series output resistor (per Figure 27 in SLOS216E). This isolates capacitive loading, prevents high-frequency ringing, and matches source impedance to minimize reflections - a standard practice in video distribution and RF test fixtures using THS4011IDGNR.
What is the purpose of pins 1 and 8 on THS4011IDGNR?
Pins 1 and 8 on THS4011IDGNR are offset nulling terminals. Connecting a 10-kΩ potentiometer between them, with the wiper tied to VCC−, allows manual adjustment of input offset voltage to <100 µV - critical for DC-coupled applications like precision integrators, photodiode transimpedance stages, and calibrated measurement front-ends using THS4011IDGNR.
