Product details
Overview
THS4041CDGNR from Texas Instruments is a single-channel, voltage-feedback operational amplifier optimized for high-speed, unity-gain-stable operation with C-load drive capability. It delivers 165 MHz bandwidth (−3 dB, CL = 0 pF), 400 V/µs slew rate, ±15 V supply operation, 100 mA output drive, and <0.01% differential gain error - enabling precision video line driving and ADC buffering in broadcast and test equipment.
For engineers reviewing the THS4041CDGNR datasheet, THS4041CDGNR pinout, THS4041CDGNR application, or THS4041CDGNR equivalent, this page provides verified specifications, MSOP-8 PowerPAD™ package details, real-world capacitive load stability behavior, and validated alternatives for high-fidelity analog signal conditioning designs.
Technical Context
The THS4041CDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with internal adaptive compensation that maintains stability across 0–1000 pF capacitive loads. Its unity-gain stability supports both inverting and noninverting configurations without external compensation.
It features low-distortion performance (−75 dBc THD at 1 MHz, RL = 150 Ω), wide common-mode input range (±13.8 V at ±15 V supplies), and rail-to-rail output swing capability (±13.6 V into 1 kΩ). The device operates over 0°C to 70°C and is specified for dual-supply (±4.5 V to ±16.5 V) or single-supply (9 V to 33 V) use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 165 MHz (−3 dB, CL = 0 pF): enables full HD video baseband amplification without roll-off |
| Slew rate | 400 V/µs (VCC = ±15 V): supports fast transient response for pulse and imaging signals |
| Output current | 100 mA (typ, RL = 20 Ω): drives 75 Ω video lines or multiple ADC inputs directly |
| THD | −75 dBc (f = 1 MHz, RL = 150 Ω): preserves signal fidelity in measurement and broadcast systems |
| Differential gain/phase | 0.01% / 0.01° (NTSC, ±15 V): meets broadcast-grade video specification for SD/HD composite |
| Supply range | ±4.5 V to ±16.5 V (dual) or 9 V to 33 V (single): compatible with legacy ±15 V and modern low-voltage rails |
| Input offset voltage | 2.5 mV (typ, TA = 25°C): minimizes DC error in precision gain stages without trimming |
Pinout & Package
THS4041CDGNR is housed in an 8-pin MSOP PowerPAD™ (DGN) package with exposed thermal pad for enhanced power dissipation (θJA = 58.4°C/W, θJC = 4.7°C/W). The PowerPAD must be soldered to PCB copper for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null connection (tie wiper of 10-kΩ pot to VCC− for fine adjustment) |
| 2 | IN− | Inverting input: accepts feedback network for stable closed-loop gain control |
| 3 | IN+ | Noninverting input: high-impedance node (1 MΩ, 1.5 pF) for signal source interface |
| 4 | VCC− | Negative supply rail: connects to system ground or negative voltage rail |
| 5 | NC | No internal connection: left floating or tied to ground per layout best practice |
| 6 | OUT | Amplified output: capable of ±13.6 V swing into 1 kΩ and 100 mA into 20 Ω |
| 7 | VCC+ | Positive supply rail: supports up to ±16.5 V absolute max rating |
| 8 | NULL | Second offset null terminal: completes external trim circuit with Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| C-load stability | Internally compensated to remain stable with 0–1000 pF capacitive loads - eliminates need for external isolation resistors in most video applications |
| Video performance | 0.01% differential gain and 0.01° differential phase error at NTSC frequencies - meets SMPTE/EBU broadcast linearity requirements |
| High output drive | 100 mA continuous output into 20 Ω - directly drives coaxial cables, multiple ADC inputs, or active filters without buffers |
| Low distortion | −75 dBc THD at 1 MHz (RL = 150 Ω) - preserves SNR in high-frequency instrumentation and medical imaging front-ends |
| Wide supply range | Operates from ±4.5 V to ±16.5 V dual supply - supports legacy ±15 V systems and newer ±5 V designs without redesign |

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 |
|---|---|---|---|
| THS4031CDGNR | 100 MHz bandwidth, lower noise (4.5 nV/√Hz), higher input bias current (10 µA) | Better suited for low-noise preamplifier stages; less ideal for >100 MHz video or fast settling | Select when noise dominates over speed; avoid for >120 MHz signal paths or video line driving |
| THS4081CDGNR | 175 MHz bandwidth, lower supply current (6.5 mA vs. 9.5 mA), reduced output drive (60 mA) | Optimized for portable/battery-powered systems requiring speed + efficiency trade-off | Choose for space-constrained, low-power designs where 60 mA drive suffices and 175 MHz margin is needed |
Compared with THS4041CDGNR, THS4031CDGNR trades bandwidth for lower noise and higher input bias, while THS4081CDGNR increases bandwidth and reduces quiescent current but sacrifices output current - making THS4041CDGNR the optimal balance for high-drive, high-fidelity video and instrumentation.

FAQ
What is the maximum capacitive load the THS4041CDGNR can drive while remaining stable?
The THS4041CDGNR is internally compensated to remain stable with capacitive loads up to 1000 pF without external compensation. Test data confirms stable step response and <5% overshoot at CL = 1000 pF under ±15 V supply conditions. For loads >1000 pF, a series isolation resistor (≥20 Ω) is recommended. This behavior is explicitly characterized in the THS4041CDGNR datasheet Figures 24–25 and Application Information section.
Does the THS4041CDGNR support single-supply operation?
Yes, the THS4041CDGNR supports single-supply operation from 9 V to 33 V. Its common-mode input range extends to within 1.2 V of the negative rail and 1.7 V of the positive rail (e.g., VICR = −3.8 V to +4.3 V at ±5 V supplies), and output swing reaches ±3.5 V into 150 Ω. These specs make it viable for 10 V–24 V single-rail systems such as portable test gear and industrial sensors.
What is the purpose of Pins 1 and 8 on the THS4041CDGNR?
Pins 1 and 8 on the THS4041CDGNR are dedicated offset null terminals. They allow external adjustment of input offset voltage using a 10-kΩ potentiometer connected between the pins, with its wiper tied to VCC−. This feature enables sub-millivolt DC calibration in precision applications - a capability not present in the dual-channel THS4042 or many competing high-speed op-amps.
How does the THS4041CDGNR compare to the THS4042CDGNR in terms of pin compatibility?
The THS4041CDGNR (single-channel) and THS4042CDGNR (dual-channel) share identical 8-pin MSOP PowerPAD™ (DGN) packaging and pinout mapping for shared functions (VCC+, VCC−, IN+, IN−, OUT), but differ in channel count and internal configuration. Pin 5 is NC on THS4041CDGNR but serves as 2IN− on THS4042CDGNR; thus, they are not pin-compatible replacements. Board layouts must be redesigned when swapping between them.
Is the THS4041CDGNR suitable for driving 75 Ω video lines in NTSC/PAL systems?
Yes - the THS4041CDGNR is explicitly characterized for broadcast video: it achieves 0.01% differential gain error and 0.01° differential phase error under NTSC conditions at ±15 V supply, and maintains flat frequency response up to 100 MHz into 150 Ω loads. Its 100 mA output drive supports direct 75 Ω termination, and its C-load stability handles typical cable capacitance (100–500 pF) without oscillation.
