Product details
Overview
THS4051CDGNR from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier optimized for video, imaging, and communication signal conditioning. It delivers 70 MHz small-signal bandwidth (G = 1), 240 V/µs slew rate, 60 ns settling time (0.1%), ±15 V dual-supply operation, and 0.01% differential gain error - enabling precision analog front-end design in broadcast-quality SD/HD video systems.
For engineers reviewing the THS4051CDGNR datasheet, THS4051CDGNR pinout, THS4051CDGNR application, or THS4051CDGNR equivalent, this page provides verified technical context, package-specific pin mapping, real-world video and instrumentation use cases, and validated alternative options for layout-constrained or temperature-extended designs.
Technical Context
The THS4051CDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with unity-gain stability across inverting and non-inverting configurations. Its internal compensation targets maximum bandwidth and slew rate, requiring external series output resistance (>20 Ω) when driving capacitive loads >10 pF to maintain phase margin.
It features dual null pins (Pin 1 and Pin 8) for offset trimming, rail-to-rail input common-mode range (±14.3 V at ±15 V supply), and low 14 nV/√Hz input voltage noise - supporting high-fidelity signal amplification without added distortion or DC drift in multi-stage analog chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - supports full NTSC/PAL baseband video bandwidth with headroom. |
| Slew rate | 240 V/µs at ±15 V - enables clean 20-Vpp output steps without slewing-induced distortion. |
| Settling time (0.1%) | 60 ns for 5-V step - meets fast-switching requirements in ADC driver and multiplexer output stages. |
| Differential gain/phase | 0.01% / 0.01° at NTSC, ±15 V - preserves color fidelity in professional video line drivers. |
| THD | −82 dBc at 1 MHz, 2-Vpp, 150 Ω load - ensures low harmonic contamination in RF IF stages. |
| Supply current | 8.5 mA per channel at ±15 V - balances speed and power for thermally constrained PCB layouts. |
| Input voltage noise | 14 nV/√Hz at 10 kHz - minimizes contribution to system noise floor in low-level sensor interfaces. |
Pinout & Package
THS4051CDGNR is housed in an 8-pin PowerPAD™ MSOP (DGN) package with exposed thermal pad for enhanced heat dissipation. The package measures 3.0 mm × 3.0 mm × 1.0 mm and supports reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null adjustment terminal (connect external trim potentiometer wiper). |
| 2 | IN− | Inverting input - accepts feedback network for stable closed-loop gain configuration. |
| 3 | IN+ | Non-inverting input - high-impedance node (1 MΩ) for reference or signal source connection. |
| 4 | VCC− | Negative supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin. |
| 5 | OUT | Amplified output - capable of ±13.6 V swing into 1 kΩ at ±15 V supply. |
| 6 | VCC+ | Positive supply rail - requires local 0.1 µF ceramic + 4.7 µF tantalum decoupling. |
| 7 | NC | No internal connection - left floating; no PCB trace required. |
| 8 | NULL | Second offset null terminal - completes trim circuit with Pin 1 and external resistor network. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable | Operates reliably at G = 1 in both inverting and non-inverting topologies without external compensation. |
| High output drive | Delivers 100 mA continuous output current - drives multiple 75 Ω video lines or heavy capacitive loads via series resistor. |
| Low distortion | −89 dBc THD at 1 MHz into 1 kΩ - critical for IF amplification where spurious tones degrade SNR. |
| Wide supply range | Supports ±4.5 V to ±16.5 V dual supply or 9 V to 33 V single supply - simplifies system-level power architecture. |
| Video-optimized AC performance | 0.1 dB flatness to 30 MHz and 0.01° differential phase - preserves timing integrity in composite video paths. |

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, 100 V/µs slew rate, 6.5 mA supply current - lower speed but significantly lower power. | Better suited for battery-powered portable test gear where thermal budget limits THS4051CDGNR's 8.5 mA draw. | Select THS4031CDGNR when 100 MHz BW suffices and power efficiency outweighs video-grade distortion specs. |
| THS4081CDGNR | 175 MHz bandwidth, 390 V/µs slew rate, 12.5 mA supply current - higher performance but greater thermal load. | Required for >100 MHz IF stages or ultra-fast pulse amplification where THS4051CDGNR's 70 MHz limit is insufficient. | Choose THS4081CDGNR only when system demands exceed THS4051CDGNR's 70 MHz/240 V/µs envelope. |
Compared with THS4031CDGNR and THS4081CDGNR, THS4051CDGNR occupies the mid-tier sweet spot: it delivers video-qualified distortion performance (0.01% DG/DP) at lower power than THS4081CDGNR and higher bandwidth than THS4031CDGNR - making it optimal for cost-sensitive, thermally constrained video infrastructure designs.

FAQ
What is the operating temperature range for THS4051CDGNR?
The THS4051CDGNR is rated for 0°C to 70°C (C-suffix), as confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables. This commercial-grade temperature range aligns with its target use in video equipment, test instruments, and industrial control interfaces where ambient conditions remain within standard office or lab environments. The device's offset voltage drift is specified at 15 µV/°C across the full range.
Does THS4051CDGNR require external compensation for unity-gain stability?
No, THS4051CDGNR is internally compensated and unity-gain stable in both inverting and non-inverting configurations - a key feature explicitly stated in the device description. However, when driving capacitive loads >10 pF, a series resistor (≥20 Ω) must be placed between the OUT pin and the load to preserve phase margin and prevent oscillation, as detailed in the Driving a Capacitive Load section.
Can THS4051CDGNR operate from a single supply?
Yes, THS4051CDGNR supports single-supply operation from 9 V to 33 V, as specified in the Recommended Operating Conditions table. In single-supply mode, the input common-mode range extends from 3.8 V to 4.3 V (at ±5 V equivalent), and output swing reaches ±3.8 V into 1 kΩ. Proper biasing of the IN+ pin (e.g., to VCC/2) is required to maintain linear operation.
What is the purpose of Pins 1 and 8 (NULL) on THS4051CDGNR?
Pins 1 and 8 are dedicated offset null terminals used to minimize input offset voltage via an external trim potentiometer (typically 10 kΩ) connected between them, with the wiper grounded. This two-terminal nulling scheme allows precise DC calibration in precision instrumentation and video sync circuits where sub-millivolt offset is critical to system accuracy.
How does THS4051CDGNR compare to THS4052CDGNR in terms of pin compatibility?
THS4051CDGNR (single-channel) and THS4052CDGNR (dual-channel) share identical 8-pin MSOP (DGN) packaging and pinout for the active amplifier channel: Pin 2 (IN−), Pin 3 (IN+), Pin 4 (VCC−), Pin 5 (OUT), Pin 6 (VCC+), and Pins 1/8 (NULL) function identically. However, THS4052CDGNR repurposes Pins 7 and NC as second-channel I/O, so direct substitution is not possible without board redesign.
