Product details
Overview
THS4011CDR 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 while operating on ±5-V to ±15-V supplies - enabling high-fidelity analog front-end design in broadcast video routing and test instrumentation.
For engineers reviewing the THS4011CDR datasheet, THS4011CDR pinout, THS4011CDR application, or THS4011CDR 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 SOIC-8 (D) package compatibility with standard PCB assembly processes.
Technical Context
The THS4011CDR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with minimal phase margin trade-offs in unity-gain stable configuration. Its internal compensation targets wideband performance while maintaining stability under noninverting G = +1 operation.
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). The device supports both dual-supply (±4.5 V to ±16.5 V) and single-supply (9 V to 32 V) operation with 7.8-mA quiescent current per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1 - supports full HD video baseband (up to ~150 MHz) with ample margin for group delay flatness. |
| Slew Rate | 310 V/µs - enables clean reproduction of fast transient signals without slewing-induced distortion in pulse amplification. |
| THD | –80 dBc at f = 1 MHz, RL = 150 Ω - meets broadcast-grade linearity requirements for NTSC/PAL composite video. |
| Differential Gain Error | 0.006% at ±15 V - ensures color fidelity in video distribution systems where <0.01% error is required for professional use. |
| Input Voltage Noise | 7.5 nV/√Hz - low enough to preserve SNR in high-gain, low-level signal paths such as medical imaging front-ends. |
| Supply Range | ±4.5 V to ±16.5 V dual supply - accommodates legacy ±5 V, ±12 V, and ±15 V system rails without level-shifting circuitry. |
| Output Current | 110 mA (typical) - drives multiple 150-Ω video loads or 75-Ω transmission lines directly without external buffers. |
Pinout & Package
THS4011CDR is packaged in an 8-pin SOIC (D package), with exposed pad option not applicable to this variant. Pin 1 is offset null input, pin 8 is offset null return to VCC–, and pins 3/2/6 are IN+/IN–/OUT respectively - matching industry-standard op-amp pinout conventions for drop-in replacement in existing designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null Input | Connects to wiper of external potentiometer for manual input offset trimming; critical for DC-coupled precision applications. |
| 2 | Inverting Input (IN−) | High-impedance node (2 MΩ) with ±14.1 V common-mode range at ±15 V supply; used for feedback and signal inversion. |
| 3 | Noninverting Input (IN+) | High-impedance node (2 MΩ); accepts DC- or AC-coupled signals up to ±14.1 V common-mode voltage at ±15 V supply. |
| 4 | VCC– | Negative supply rail connection; must be decoupled with 0.1 µF ceramic capacitor placed ≤0.1 inch from pin. |
| 5 | NC | No internal connection - left unconnected; no routing or thermal consideration required. |
| 6 | Output (OUT) | Capable of ±13.5 V swing into 1 kΩ; drives capacitive loads ≥10 pF only when series isolation resistor (≥20 Ω) is used. |
| 7 | VCC+ | Positive supply rail connection; requires dedicated 0.1 µF ceramic + 6.8 µF tantalum decoupling per TI layout guidelines. |
| 8 | Offset Null Return | Connected to VCC– to complete nulling circuit; ties internal bias network to negative rail for offset adjustment. |
Key Features

Use Scenario: Conditioning analog outputs from 12-bit DACs in automated test equipment before digitization at 20 MSPS. IC Role / Device Role / Timing Role: Fast-settling output buffer isolating DAC from ADC input capacitance and maintaining signal integrity during sampling windows. Use Value: 37-ns 0.1% settling time guarantees full-scale step accuracy within one sample period, eliminating missing-code errors. |
| Medical Ultrasound Beamforming | RF Signal Chain IF Amplifier |
|
Use Scenario: Amplifying low-amplitude echo return signals from piezoelectric transducers in portable ultrasound systems. IC Role / Device Role / Timing Role: Low-noise, wideband gain stage in receive path prior to ADC, operating at ±5 V for power efficiency. Use Value: 7.5-nV/√Hz input voltage noise preserves weak echo SNR, while 270-MHz bandwidth at ±5 V supports 5–15 MHz transducer frequencies. |
Use Scenario: Intermediate-frequency amplification in software-defined radio receivers processing 70-MHz IF signals with variable gain control. IC Role / Device Role / Timing Role: Fixed-gain, high-linearity IF buffer between mixer and ADC, configured in noninverting G = +1 with 100-Ω feedback resistor.

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 |
|---|---|---|---|
| THS4031CDR | 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, medium-bandwidth applications like precision sensor interfaces where speed is secondary. | Select THS4031CDR only if bandwidth demand is ≤100 MHz and noise is prioritized over slew rate and load drive. |
| OPA695IDBVR | Higher 1.7-GHz bandwidth and 4300-V/µs slew rate, but higher 12.6-nV/√Hz noise and no offset nulling pins. | Targeted at RF/IF gain blocks and ultra-high-speed pulse amplification where DC precision is not required. | Choose OPA695IDBVR only for >500-MHz small-signal applications; avoid where DC accuracy or video linearity matters. |
Compared with THS4011CDR, THS4031CDR trades bandwidth and drive for lower noise, while OPA695IDBVR sacrifices DC precision and linear distortion performance for extreme speed - making THS4011CDR the optimal balance for video, instrumentation, and mixed-signal front-ends requiring both speed and fidelity.

FAQ
What is the maximum operating temperature range for the THS4011CDR?
The THS4011CDR is rated for operation from 0°C to +70°C (C-suffix grade). This commercial temperature range is validated per TI's SLOS216E datasheet and applies to all electrical specifications unless otherwise noted. For extended-range alternatives, consider the THS4011IDR (–40°C to +85°C) or THS4011MDR (–55°C to +125°C), which share identical pinout and core performance.
Does the THS4011CDR support single-supply operation?
Yes, the THS4011CDR supports single-supply operation from 9 V to 32 V. When operated on a single rail (e.g., +15 V with ground reference), the input common-mode range extends to within 1.5 V of ground and the output swings to within 1.5 V of ground, enabling true DC-coupled signal handling in systems without negative rails.
Can the THS4011CDR drive 75-Ω transmission lines directly?
Yes - the THS4011CDR delivers 110 mA output current and can drive 75-Ω loads directly. For optimal impedance matching and stability, place a 75-Ω series resistor at the output pin (pin 6) to isolate capacitive loading and terminate the line, as recommended in TI's Application Information section for capacitive load driving.
What is the purpose of pins 1 and 8 on the THS4011CDR?
Pins 1 and 8 are dedicated offset nulling terminals. Connecting a 10-kΩ potentiometer between them and tying the wiper to VCC– (pin 4) allows manual adjustment of input offset voltage - a feature critical for DC-coupled applications like precision transducer signal conditioning where sub-millivolt offset is unacceptable.
How does the THS4011CDR compare to the dual-channel THS4012CDR in pin compatibility?
The THS4011CDR (single-channel) and THS4012CDR (dual-channel) share identical SOIC-8 pinouts for their respective active channels: pins 2/3/6 map to IN−/IN+/OUT for Channel 1 in both devices. However, THS4012CDR repurposes pins 5 and 8 for Channel 2's IN− and IN+, making it not pin-compatible for direct substitution without board redesign.
