Product details
Overview
THS4011CDGN from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier in an 8-pin MSOP PowerPAD™ package. It delivers 290-MHz bandwidth (G = 1), 310-V/µs slew rate, and 37-ns 0.1% settling time, with ±15-V supply capability and 110-mA output drive-enabling precision video signal conditioning and high-fidelity analog front-end buffering in broadcast-grade equipment.
For engineers reviewing the THS4011CDGN datasheet, THS4011CDGN pinout, THS4011CDGN application, or THS4011CDGN equivalent, this page provides verified electrical specifications, thermal design guidance for the DGN PowerPAD™ package, real-world video performance metrics (0.006% differential gain error), and validated alternative options for high-speed op-amp selection.
Technical Context
The THS4011CDGN uses a dielectrically isolated complementary bipolar process with GHz fT transistors to achieve wide bandwidth and low distortion. Its internal compensation targets stability in noninverting unity-gain configurations while preserving 290-MHz small-signal bandwidth and 70-MHz 0.1-dB flatness.
It operates from ±4.5 V to ±16.5 V dual supplies (or 9–32 V single supply), supports rail-to-rail output swing into 150 Ω (±3.4 V at ±5 V, ±13.5 V at ±15 V), and features 7.5-nV/√Hz input voltage noise and –80 dBc THD at 1 MHz with 150-Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1, ±15 V - enables baseband video and fast pulse amplification without roll-off |
| Slew Rate | 310 V/µs at ±15 V - supports clean 20-VPP output at >4 MHz full-power bandwidth |
| Settling Time (0.1%) | 37 ns at ±15 V - meets tight timing windows in high-speed data acquisition systems |
| Total Harmonic Distortion | –80 dBc at 1 MHz, ±15 V, 150 Ω - preserves signal fidelity in RF IF stages and test instrumentation |
| Differential Gain Error | 0.006% at NTSC, ±15 V - ensures color accuracy in professional video routing and distribution |
| Supply Voltage Range | ±4.5 V to ±16.5 V dual supply - compatible with legacy ±5 V, ±12 V, and ±15 V analog subsystems |
| Output Current Drive | 110 mA typical into 20 Ω - drives multiple 75-Ω video lines or low-Z ADC inputs directly |
Pinout & Package
The THS4011CDGN is housed in an 8-pin MSOP PowerPAD™ (DGN) package with exposed thermal pad on the underside. This thermally enhanced package achieves 58.4°C/W junction-to-ambient (qJA) when properly soldered to a PCB copper area with five 13-mil vias connected to an internal ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout best practice |
| 2 | IN− | Inverting input - high-impedance node requiring short trace and guard ring for stability |
| 3 | IN+ | Noninverting input - reference point for offset nulling; sensitive to capacitive loading |
| 4 | VCC− | Negative supply rail - requires local 0.1-µF ceramic + 6.8-µF tantalum decoupling |
| 5 | NC | No internal connection - must be left floating or grounded |
| 6 | VCC+ | Positive supply rail - same decoupling as VCC−; critical for PSRR >75 dB |
| 7 | OUT | Amplifier output - series 20-Ω resistor required for >10-pF capacitive loads to prevent ringing |
| 8 | NC | No internal connection - used for offset nulling only in D/DGN packages (pin 1 and 8 tied to pot wiper) |
Key Features
| Feature | Design Value |
|---|---|
| PowerPAD™ thermal enhancement | 2.14 W power dissipation rating at TA = 25°C - enables continuous operation at full output current without heatsink |
| Video-optimized AC performance | 0.01° differential phase error at NTSC - maintains chroma timing integrity across multi-channel video switchers |
| Low-noise architecture | 7.5 nV/√Hz input voltage noise at 10 kHz - minimizes SNR degradation in low-level sensor signal chains |
| High-output-current capability | 110 mA drive into 20 Ω - eliminates need for external buffer stages in composite video drivers |
| Offset nulling provision | Pins 1 and 8 support external 10-kΩ potentiometer - allows trimming of <6 mV input offset to sub-mV level |

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 |
|---|---|---|---|
| THS4011IDGN | Wider operating temperature range (–40°C to +85°C vs. 0°C to +70°C); identical electrical specs and pinout | Suitable for industrial motor control feedback loops and outdoor broadcast enclosures requiring extended thermal margin | Select THS4011IDGN when ambient temperature exceeds 70°C or lifecycle reliability under thermal cycling is critical |
| THS4031CDGN | Lower 100-MHz bandwidth but superior 1.9-nV/√Hz voltage noise; same DGN package and pin compatibility | Better suited for low-frequency, ultra-low-noise sensor interfaces (e.g., EEG, precision strain gauges) than video or wideband RF | Choose THS4031CDGN when noise dominates over bandwidth requirements and THS4011CDGN's 290-MHz capability is unused |
Compared with THS4011CDGN, THS4011IDGN offers guaranteed performance over industrial temperatures without sacrificing speed or drive, while THS4031CDGN trades bandwidth for significantly lower noise-making it optimal for DC-coupled, low-frequency precision applications rather than video or fast pulse handling.

FAQ
What is the maximum supply voltage for THS4011CDGN?
The THS4011CDGN supports dual-supply operation from ±4.5 V to ±16.5 V, with absolute maximum ratings up to ±16.5 V. Exceeding this risks permanent damage. For reliable operation, maintain supply rails within ±16 V, especially under high-output-current conditions where internal power dissipation increases.
Does THS4011CDGN require external compensation for unity-gain stability?
No, the THS4011CDGN is internally compensated for unity-gain stability in noninverting configurations. However, for optimal settling behavior and minimal ringing, TI recommends using a 100-Ω feedback resistor in G = +1 circuits, as shown in Figure 30 of the THS4011CDGN datasheet.
Can THS4011CDGN drive a 75-Ω video load directly?
Yes, THS4011CDGN delivers 110 mA output current and supports ±3.4 V swing into 150 Ω at ±5 V supply-sufficient for driving 75-Ω loads with proper source termination. Use a 75-Ω series resistor at the output to match line impedance and suppress reflections in video transmission.
How is thermal management handled in the THS4011CDGN DGN package?
The THS4011CDGN DGN package incorporates a PowerPAD™ thermal pad on its underside. To achieve the rated 2.14 W power dissipation, the pad must be soldered to a PCB copper area with five 13-mil vias connected to an internal ground plane-ensuring low thermal resistance and stable junction temperature under full load.
Is THS4011CDGN pin-compatible with other packages in the THS401x family?
Yes, the THS4011CDGN shares identical pinout with the THS4011CD (SOIC-8) and THS4011IDGN variants. Pin functions (IN−, IN+, OUT, VCC+, VCC−, NC) are fully aligned across D, DGN, and JG packages-enabling drop-in replacement when thermal or board-space constraints dictate package change.
