Product details
Overview
THS4041ID from Texas Instruments is a single-channel, voltage-feedback operational amplifier optimized for high-speed, unity-gain-stable operation with capacitive load drive capability. It delivers 165 MHz small-signal bandwidth (±15 V, CL = 0 pF), 400 V/µs slew rate, and drives up to 100 mA into 20 Ω while maintaining <0.01% differential gain error - making it suitable for precision video line driving and ADC buffering in industrial imaging systems.
For engineers reviewing the THS4041ID datasheet, THS4041ID pinout, THS4041ID application, or THS4041ID equivalent, key selection criteria include capacitive-load stability without external compensation, ±4.5 V to ±16.5 V dual-supply flexibility, low THD (−75 dBc at 1 MHz, RL = 150 Ω), and −40°C to +85°C industrial temperature rating.
Technical Context
The THS4041ID uses a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth and fast settling (120 ns to 0.1%, 250 ns to 0.01%). Its internal C-stable architecture dynamically adjusts dominant-pole compensation based on output capacitance, ensuring stability across 0–1000 pF loads without external components.
It supports both inverting and noninverting configurations at all gains, features dedicated NULL pins (1 & 8) for offset trimming, and maintains low distortion (−89 dBc at 1 MHz, RL = 1 kΩ) and high CMRR (≥80 dB) over its full operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 165 MHz (±15 V, CL = 0 pF): enables baseband video and high-fidelity signal amplification up to NTSC/PAL frequencies. |
| Slew rate | 400 V/µs (±15 V, 20-V step): supports fast transient response in pulse-amplification and data-acquisition front-ends. |
| THD | −75 dBc (1 MHz, RL = 150 Ω): ensures minimal harmonic corruption in broadcast-quality video distribution. |
| Output drive | 100 mA (±15 V, RL = 20 Ω): directly drives coaxial cables, multiple 75 Ω loads, or low-impedance ADC inputs. |
| Supply range | ±4.5 V to ±16.5 V: accommodates legacy ±5 V, ±12 V, and ±15 V systems without level-shifting circuitry. |
| Differential gain/phase | 0.01% / 0.01° (NTSC, ±15 V): meets broadcast video fidelity requirements for analog RGB or composite video paths. |
| Operating temp | −40°C to +85°C (I-suffix): certified for use in industrial cameras, medical imaging, and automated test equipment. |
Pinout & Package
THS4041ID is packaged in an 8-pin SOIC (D package) with exposed thermal pad (PowerPAD™). The package supports high-power dissipation (740 mW at TA = 25°C) and improved thermal performance in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null adjustment terminal; connect potentiometer wiper to VCC− for fine-tuning input offset voltage. |
| 2 | IN− | Inverting input; high-impedance node (1 MΩ) with 1.5 pF capacitance for stable feedback network design. |
| 3 | IN+ | Noninverting input; matched to IN− for optimal common-mode rejection and low input bias current (2.5 µA typ). |
| 4 | VCC− | Negative supply rail; must be decoupled with 0.1 µF ceramic capacitor near pin for high-frequency PSRR stability. |
| 5 | NULL | Second offset null terminal; connect opposite end of potentiometer to VCC− to complete nulling circuit. |
| 6 | OUT | Amplifier output; capable of ±13 V swing into 1 kΩ and sustains 100 mA peak current into 20 Ω loads. |
| 7 | VCC+ | Positive supply rail; accepts up to ±16.5 V absolute max; requires local 0.1 µF decoupling for noise immunity. |
| 8 | NC | No internal connection; left unconnected per TI datasheet - not used for thermal or electrical functions. |
Key Features
| Feature | Design Value |
|---|---|
| C-stable architecture | Internally compensates for 0–1000 pF capacitive loads without external components, eliminating need for isolation resistors in most video applications. |
| Unity-gain stability | Guaranteed stable in both inverting and noninverting configurations at gain = 1, simplifying design for buffer and line-driver topologies. |
| Low-distortion video performance | 0.01% differential gain and 0.01° differential phase error meet SMPTE/ITU-R BT.601 broadcast standards for analog video. |
| High-output current | Delivers 100 mA continuous output current, enabling direct drive of multiple 75 Ω video lines or low-Z ADC inputs without external buffers. |
| Offset null capability | Pins 1 and 8 support external potentiometer-based trimming, reducing system-level offset errors to sub-mV levels in precision instrumentation. |

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 |
|---|---|---|---|
| THS4031ID | 100 MHz bandwidth, lower 1.6 nV/√Hz voltage noise, but higher THD (−65 dBc @ 1 MHz) and no NULL pins. | Better suited for low-noise preamplifier stages than video line driving; lacks offset trim capability. | Select THS4031ID when ultra-low noise dominates over video fidelity and offset adjustability. |
| THS4081ID | 175 MHz bandwidth, 1.8 mA supply current (vs. 9.5 mA), but reduced output drive (60 mA) and higher THD (−68 dBc @ 1 MHz). | Optimized for battery-powered portable instruments where power efficiency outweighs drive strength. | Choose THS4081ID only when supply current <2 mA is mandatory and 100 mA output is unnecessary. |
Compared with THS4041ID, THS4031ID trades bandwidth and video accuracy for lower noise, while THS4081ID reduces power at the expense of output current and distortion performance - neither offers pin-compatible replacement due to differing NULL pin allocation and thermal pad requirements.

FAQ
What is the maximum capacitive load the THS4041ID can drive without external compensation?
The THS4041ID is internally compensated to remain stable with capacitive loads up to 1000 pF without external components. Datasheet Figure 24 confirms ≤5% overshoot at 1000 pF under 1 V and 5 V step conditions with ±15 V supplies. For loads >1000 pF, a series isolation resistor (≥20 Ω) is recommended per TI Application Report SLOA013.
Does the THS4041ID support single-supply operation?
Yes, the THS4041ID operates from a single supply of 9 V to 32 V (VCC = 9–32 V), as specified in the Recommended Operating Conditions table. Input common-mode range extends to within 1.2 V of rails (e.g., ±3.8 V at ±5 V supply), and output swing reaches ±3.5 V into 150 Ω - enabling true single-supply video and sensor interface designs.
How does the THS4041ID achieve unity-gain stability with high slew rate?
The THS4041ID achieves unity-gain stability through proprietary internal C-stable compensation that senses output capacitance and adjusts the dominant pole in real time. Unlike traditional dominant-pole compensation, this architecture preserves 400 V/µs slew rate and 165 MHz bandwidth while maintaining ≥45° phase margin across 0–1000 pF loads - verified in Figures 6–11 and Application Information section.
Can the THS4041ID replace the THS4011 in existing designs?
No - the THS4041ID is not a drop-in replacement for THS4011. While both are TI high-speed op-amps, THS4011 has different pinout (no NULL pins), higher 290 MHz bandwidth but poorer capacitive-load stability, and no offset null capability. THS4041ID's NULL pins (1 & 8) and C-stable architecture require PCB layout changes if substituting into THS4011 designs.
What is the thermal performance of the THS4041ID in SOIC (D) package?
The THS4041ID in SOIC (D) package has θJA = 167°C/W (JEDEC Low-K board) and θJC = 38.3°C/W, supporting 740 mW maximum power dissipation at TA = 25°C. With proper 2-layer PCB copper pour and thermal vias under the PowerPAD™, junction temperature rise remains within safe limits even at full 100 mA output into 20 Ω at ±15 V.
