Product details
Overview
THS4011CD from Texas Instruments is a single-channel, voltage-feedback high-speed 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, operating from ±4.5 V to ±16 V supplies. It is used in analog front-end stages of broadcast video equipment, high-resolution imaging systems, and test instrumentation requiring low distortion and fast transient response.
For engineers reviewing the THS4011CD datasheet, THS4011CD pinout, THS4011CD application, or THS4011CD equivalent, key selection criteria include its 7.5-nV/√Hz input voltage noise, –80 dBc THD at 1 MHz, 0.006% differential gain error, ±13.5-V output swing into 1 kΩ, and SOIC-8 (D) package thermal performance with optional PowerPAD™ (DGN) variant.
Technical Context
The THS4011CD employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, supporting voltage-feedback architecture with internal compensation optimized for unity-gain stability and wideband operation. Its design targets minimal phase margin degradation in noninverting G = +1 configurations while maintaining 290-MHz small-signal bandwidth.
It features rail-to-rail input common-mode range (±14.1 V at ±15 V supply), 110-mA output drive capability into 20 Ω, and integrated offset nulling via pins 1 and 8 - all implemented without external compensation components for standard gain configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1; enables baseband video amplification up to 70 MHz with 0.1-dB flatness. |
| Slew Rate | 310 V/µs at ±15 V; supports full-scale 20-VPP output transitions in under 65 ns without slewing distortion. |
| Total Harmonic Distortion | –80 dBc at 1 MHz, 150 Ω load; meets broadcast-grade NTSC/PAL differential gain/phase specs (0.006%/0.01°). |
| Input Voltage Noise | 7.5 nV/√Hz at 10 kHz; critical for preserving SNR in low-level signal amplification chains. |
| Supply Voltage Range | ±4.5 V to ±16 V dual supply; accommodates legacy ±5 V, ±12 V, and ±15 V system rails. |
| Output Current Drive | 110 mA typical into 20 Ω; drives multiple 75-Ω video lines or capacitive loads with series isolation resistor. |
| Settling Time (0.1%) | 37 ns at ±15 V; ensures accurate pulse fidelity in digitizer front-ends and waveform reconstruction circuits. |
Pinout & Package
THS4011CD is packaged in an 8-pin SOIC (D package), with exposed thermal pad option available as THS4011CDGN. Pin 1 is offset null adjust; pins 1 and 8 form null potentiometer terminals. Pin 4 is VCC−; pin 8 is VCC+. No internal connection on pins 1 and 8 unless used for offset nulling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null Input | Connects to wiper of external 10-kΩ potentiometer for manual input offset correction; NC if unused. |
| 2 | Inverting Input (IN−) | Differential input node; requires matched trace length and impedance control for high-frequency stability. |
| 3 | Noninverting Input (IN+) | Differential input node; sensitive to stray capacitance; keep trace short and guard with ground. |
| 4 | VCC− | Negative supply rail; decouple with 0.1 µF ceramic + 6.8 µF tantalum close to pin. |
| 5 | NC | No internal connection; leave unconnected or tie to ground only if required by layout EMI mitigation. |
| 6 | Output (OUT) | High-current output capable of driving 150 Ω loads directly; add 20 Ω series resistor for >10 pF capacitive loads. |
| 7 | VCC+ | Positive supply rail; decouple identically to pin 4; avoid shared traces with digital supplies. |
| 8 | Offset Null Input | Connects to one end of external 10-kΩ potentiometer; other end tied to VCC− for null adjustment range. |
Key Features
| Feature | Design Value |
|---|---|
| 290-MHz Unity-Gain Bandwidth | Enables DC–70 MHz video signal amplification with <0.1 dB gain flatness, eliminating need for external peaking networks. |
| 310-V/µs Slew Rate | Supports full-scale 20-VPP output steps within 65 ns, critical for pulse-amplifier and fast DAC buffer applications. |
| –80 dBc THD at 1 MHz | Meets broadcast video linearity requirements without post-compensation, reducing system calibration overhead. |
| 0.006% Differential Gain Error | Preserves color fidelity in NTSC/PAL composite video paths, enabling direct replacement of legacy video op-amps. |
| Offset Nulling Terminals | Allows trimming of input offset voltage down to <1 mV in production test, improving DC accuracy in precision signal chains. |
| PowerPAD™ Option (DGN) | Reduces thermal resistance to 4.7°C/W (qJC), enabling 2.14 W power dissipation at TA = 25°C - 2.9× higher than standard D package. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4031CD | 100-MHz bandwidth, lower 4.5-nV/√Hz noise, but reduced slew rate (175 V/µs) and output drive (60 mA). | Better suited for low-noise preamp stages where bandwidth ≤100 MHz suffices; not viable for 70-MHz video or fast pulse applications. | Select THS4031CD only when noise dominates over speed; THS4011CD remains mandatory for >200-MHz signal paths. |
| OPA695ID | Higher 1.7-GHz bandwidth and 4300-V/µs slew rate, but higher 11.5-nV/√Hz noise and no offset null pins. | Targeted at RF IF amplification and optical receiver TIA stages; lacks video-optimized distortion specs and differential gain/phase characterization. | Choose OPA695ID for GHz-range small-signal gain; THS4011CD is preferred for DC–70 MHz video and precision pulse fidelity. |
Compared with THS4031CD and OPA695ID, THS4011CD uniquely balances 290-MHz bandwidth, –80 dBc THD, 0.006% differential gain, and offset nulling - making it the only drop-in solution for broadcast video and high-fidelity data acquisition where both speed and linearity are simultaneously constrained.

FAQ
What is the maximum supply voltage rating for THS4011CD?
The THS4011CD has an absolute maximum supply voltage rating of ±16.5 V per rail. Operation beyond this risks permanent damage. Recommended operating range is ±4.5 V to ±16 V, with full electrical specifications guaranteed across ±5 V, ±12 V, and ±15 V configurations. Derating is required above ±15 V due to increased power dissipation and junction temperature rise.
Does THS4011CD support single-supply operation?
Yes, THS4011CD supports single-supply operation from 9 V to 32 V. Input common-mode range extends to within 1.5 V of the negative rail (typically ground), and output swing reaches within 1.5 V of each rail under light loads. For optimal DC accuracy in single-supply mode, bias the IN+ pin at mid-supply using a resistor divider and bypass capacitor.
How is offset voltage adjusted on THS4011CD?
THS4011CD provides dedicated offset nulling terminals at pins 1 and 8. Connect a 10-kΩ potentiometer between these pins, with its wiper tied to VCC− (pin 4). Adjusting the potentiometer changes the internal current balance, trimming input offset voltage to <1 mV. Do not connect pins 1 or 8 to any other node unless performing nulling - they are otherwise NC.
Can THS4011CD drive a 75-Ω video load directly?
Yes, THS4011CD can drive a 75-Ω load directly with full 20-VPP output swing at ±15 V supply. However, for optimal stability and minimal ringing, place a 75-Ω series resistor at the output to match line impedance and isolate capacitive effects. This configuration maintains 0.006% differential gain error and preserves NTSC/PAL timing integrity.
What thermal considerations apply to THS4011CD in SOIC-8 (D) package?
The SOIC-8 (D) package has a junction-to-ambient thermal resistance (qJA) of 167°C/W on JEDEC Low-K board. At 7.8 mA quiescent current and ±15 V supply, power dissipation is ~234 mW - resulting in ~39°C junction rise above ambient. For continuous high-output-current operation, use adequate copper pour, thermal vias, or consider the thermally enhanced THS4011CDGN (qJA = 58.4°C/W) to maintain TJ < 125°C.
