Product details
Overview
THS4011CDGNR from Texas Instruments is a single-channel, voltage-feedback high-speed operational amplifier optimized for low-distortion video and precision analog signal conditioning. It delivers 290-MHz bandwidth (G = 1), 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 broadcast video line drivers, high-resolution imaging front-ends, and test equipment signal paths.
For engineers reviewing the THS4011CDGNR datasheet, THS4011CDGNR pinout, THS4011CDGNR application, or THS4011CDGNR equivalent, key selection criteria include its 7.5-nV/√Hz input voltage noise, ±13.5-V output swing into 1 kΩ, 0.006% differential gain error at NTSC, and MSOP PowerPAD™ thermal performance - all critical for wideband, low-error analog signal chains.
Technical Context
The THS4011CDGNR employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth with high slew rate and low distortion. Its internal compensation targets stability in unity-gain noninverting configurations while maintaining 290-MHz small-signal bandwidth and 70-MHz 0.1-dB flatness.
It features rail-to-rail output swing capability (±13.5 V into 1 kΩ), 110-mA output current drive, and integrated offset nulling via pins 1 and 8. The DGN package includes an electrically isolated thermal pad for enhanced power dissipation (2.14 W at TA = 25°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1 - supports full HD video baseband and fast pulse amplification without attenuation |
| Slew Rate | 310 V/µs - enables clean reproduction of >100-MHz square waves with minimal edge distortion |
| Total Harmonic Distortion | –80 dBc at 1 MHz, RL = 150 Ω - ensures fidelity in RF sampling and composite video signal paths |
| Input Voltage Noise | 7.5 nV/√Hz - preserves SNR in low-level signal amplification stages before ADCs |
| Differential Gain Error | 0.006% at NTSC, G = 2 - meets broadcast-grade color accuracy requirements for SD/HD video |
| Supply Voltage Range | ±4.5 V to ±16 V (dual) or 9 V to 32 V (single) - supports industrial, instrumentation, and legacy video supply rails |
| Output Current Drive | 110 mA (typical) - drives multiple 75-Ω video loads or heavy capacitive loads with series isolation resistor |
Pinout & Package
THS4011CDGNR is housed in an 8-pin MSOP PowerPAD™ (DGN) package with exposed thermal pad on underside. The package supports tape-and-reel delivery (R suffix) and provides 2.14 W power dissipation at TA = 25°C when properly thermally anchored.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (IN− side) | Connects to potentiometer wiper for manual input offset correction; referenced to VCC− |
| 2 | Inverting Input (IN−) | Differential input node; requires short trace routing to minimize parasitic capacitance and phase shift |
| 3 | Noninverting Input (IN+) | Differential input node; may accept RC low-pass filter for anti-aliasing or noise reduction |
| 4 | VCC− | Negative supply rail; must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum close to pin |
| 5 | NC | No internal connection - leave unconnected; not bonded or functional |
| 6 | Output (OUT) | Capable of ±13.5 V swing into 1 kΩ; requires ≥20 Ω series resistor when driving >10 pF load |
| 7 | VCC+ | Positive supply rail; decoupling identical to VCC−; shared ground plane recommended |
| 8 | Offset Null (IN+ side) | Connects to potentiometer end; forms adjustable voltage divider with Pin 1 for offset trimming |
Key Features

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 |
|---|---|---|---|
| THS4011IDGNR | Wider temperature range (–40°C to +85°C) vs. THS4011CDGNR (0°C to +70°C); otherwise identical electrical specs and pinout | Suitable for industrial environments with extended ambient temperature swings | Select THS4011IDGNR when operation beyond 70°C ambient is required; same PCB layout and thermal design apply |
| THS4031CDGNR | Lower bandwidth (100 MHz), lower noise (4.5 nV/√Hz), higher input bias current (1.5 µA); different internal compensation | Better suited for low-noise, medium-bandwidth applications where distortion is less critical than noise floor | Choose THS4031CDGNR only if bandwidth demand ≤100 MHz and input-referred noise is priority over slew rate or video fidelity |
Compared with THS4011CDGNR, THS4011IDGNR offers extended temperature operation without trade-offs, while THS4031CDGNR sacrifices bandwidth and slew rate for lower voltage noise - making it unsuitable as a drop-in replacement in video or fast-pulse applications.

FAQ
What is the maximum supply voltage for THS4011CDGNR?
The THS4011CDGNR supports dual-supply operation from ±4.5 V to ±16.5 V absolute maximum, with recommended operating range of ±4.5 V to ±16 V. Exceeding ±16.5 V risks permanent damage per Absolute Maximum Ratings. For single-supply use, it operates from 9 V to 32 V, with output swing referenced to mid-rail.
Does THS4011CDGNR require external compensation for unity-gain stability?
No - the THS4011CDGNR is internally compensated for unity-gain stability in noninverting configurations. However, optimal settling (minimal ringing) is achieved using a 100-Ω feedback resistor. For inverting configurations or capacitive loads >10 pF, a ≥20-Ω series resistor at the output is mandatory to maintain phase margin.
How is the thermal pad on the THS4011CDGNR package connected?
The exposed thermal pad on the THS4011CDGNR is electrically isolated from all pins and must be soldered to a dedicated copper pour connected to PCB ground or a thermal plane via ≥5 vias (13-mil diameter). It is not connected to any signal or supply net - its sole purpose is thermal conduction, not electrical functionality.
Can THS4011CDGNR drive 75-Ω video loads directly?
Yes - the THS4011CDGNR delivers 110 mA output current and supports ±3.4 V swing into 150 Ω, making it suitable for driving 75-Ω lines when configured with proper source termination. A 75-Ω series resistor at the output provides impedance matching and isolates capacitive load effects, preserving signal integrity.
What is the purpose of Pins 1 and 8 on THS4011CDGNR?
Pins 1 and 8 on the THS4011CDGNR provide offset nulling capability: Pin 1 connects to one end of a 10-kΩ potentiometer, Pin 8 to the other end, and the wiper ties to VCC−. This forms an adjustable voltage divider that injects corrective current into the input stage, reducing input offset voltage to <0.5 mV after calibration.
