Product details
Overview
THS4061ID from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier optimized for video, imaging, and communication signal conditioning. It delivers 180 MHz bandwidth (G = 1, −3 dB), 400 V/µs slew rate, and 40 ns settling time (0.1%), with ±15 V supply operation and 115 mA output drive-enabling robust line driving in professional video systems.
For engineers reviewing the THS4061ID datasheet, THS4061ID pinout, THS4061ID application, or THS4061ID equivalent, key selection criteria include its −72 dBc THD at 1 MHz, 0.02% differential gain / 0.02° differential phase error (NTSC, ±15 V), stable unity-gain operation, and SOIC-8 industrial temperature range (−40°C to +85°C).
Technical Context
The THS4061ID uses a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth and low distortion without external compensation. Its internal frequency compensation ensures stability across all gains in both inverting and noninverting configurations.
It features dual null pins (1 and 8) for offset trimming, rail-to-rail input common-mode range (±13.8 V at ±15 V supplies), and output swing to ±13.5 V into 1 kΩ-supporting high-fidelity analog signal paths in DC-coupled video and precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3 dB) | 180 MHz at G = 1, ±15 V - supports full HD baseband video and fast pulse amplification without roll-off. |
| Slew Rate | 400 V/µs at ±15 V - enables clean reproduction of fast edges in digital video sync signals and pulse generators. |
| Settling Time (0.1%) | 40 ns for 5-V step - ensures accurate pixel-level timing in high-speed ADC/DAC buffer stages. |
| Differential Gain/Phase | 0.02% / 0.02° at NTSC, G = 2, ±15 V - meets broadcast-grade video fidelity requirements for RGB/YUV distribution. |
| Total Harmonic Distortion | −72 dBc at f = 1 MHz - minimizes spectral contamination in IF and baseband signal chains. |
| Supply Voltage Range | ±4.5 V to ±16.5 V dual supply - accommodates legacy ±5 V, ±12 V, and ±15 V system rails without level-shifting. |
| Quiescent Current | 7.8 mA per channel at ±15 V - balances performance and power in multi-channel video processing modules. |
Pinout & Package
THS4061ID is housed in an 8-pin SOIC (D) package with standard pinout and surface-mount footprint compatible with automated assembly. Thermal design follows JEDEC MS-012, with exposed pad not present (PowerPAD® is exclusive to DGN variant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null Input | Connects to wiper of external potentiometer for fine-tuning input offset voltage; required only for ultra-low-drift applications. |
| 2 (IN−) | Inverting Input | High-impedance node for feedback network connection; layout must minimize trace length and stray capacitance. |
| 3 (IN+) | Noninverting Input | High-impedance input for signal source; requires matched trace impedance and guard ring in high-frequency designs. |
| 4 (VCC−) | Negative Supply Rail | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum close to pin; shared ground plane avoided under input/output traces. |
| 5 (NC) | No Internal Connection | Unbonded pad; left floating or tied to ground only if required by PCB mechanical constraints-no electrical function. |
| 6 (OUT) | Amplifier Output | Capable of ±11.5 V swing into 250 Ω; series resistor (≥20 Ω) required when driving >10 pF capacitive loads. |
| 7 (VCC+) | Positive Supply Rail | Identical decoupling requirement as VCC−; separate 0.1 µF ceramic capacitor mandatory per supply pin. |
| 8 (NULL) | Offset Null Reference | Connected to negative supply (VCC−) when using external nulling pot; unused pins may be left open. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable | Operates without external compensation in G = 1 noninverting or inverting configurations-reduces BOM count and layout complexity. |
| Video-optimized AC performance | 75 MHz 0.1 dB flatness and <0.02% differential gain error enable direct replacement of legacy video op-amps in SD/HD routing hardware. |
| High output current drive | 115 mA typical into 20 Ω allows driving multiple 75 Ω video lines or heavy capacitive loads without external buffers. |
| Industrial temperature range | −40°C to +85°C operation validated across full electrical specs-suitable for outdoor video encoders and industrial vision systems. |
| Low THD + noise | −72 dBc THD at 1 MHz and 14.5 nV/√Hz input voltage noise preserve SNR in sensitive analog front-ends and RF sampling paths. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4031ID | 100 MHz bandwidth, lower power (5.3 mA), higher input noise (17 nV/√Hz) | Better suited for low-power portable instrumentation where bandwidth ≤100 MHz suffices | Select THS4031ID when thermal budget or battery life outweighs need for 180 MHz bandwidth and video-grade linearity. |
| OPA695ID | 1.7 GHz bandwidth, 4300 V/µs slew rate, higher quiescent current (12.5 mA), no offset null pins | Targeted at RF IF amplification and ultra-high-speed pulse applications beyond video bandwidth | Choose OPA695ID only when system requires >500 MHz small-signal bandwidth; THS4061ID remains optimal for video and general-purpose 180 MHz use. |
Compared with THS4031ID and OPA695ID, the THS4061ID uniquely balances 180 MHz bandwidth, video-optimized distortion performance, offset trimming capability, and industrial temperature rating-making it the preferred choice for broadcast infrastructure and embedded vision systems requiring proven reliability and signal fidelity.

FAQ
What is the operating temperature range for THS4061ID?
The THS4061ID is rated for industrial operation from −40°C to +85°C, with full electrical specifications guaranteed across this range-including bandwidth, slew rate, and distortion performance. This makes THS4061ID suitable for outdoor video equipment, factory automation vision systems, and ruggedized test instruments where ambient conditions exceed commercial limits.
Does THS4061ID require external compensation for unity-gain stability?
No, THS4061ID is internally compensated and unity-gain stable in both inverting and noninverting configurations. The device maintains ≥45° phase margin at G = 1 without external components. For optimal settling behavior, TI recommends a 270 Ω feedback resistor in noninverting unity-gain setups to minimize peaking and ringing-verified in the THS4061ID datasheet Figure 27.
Can THS4061ID drive 75 Ω video loads directly?
Yes, THS4061ID can drive 75 Ω video loads directly in gain-of-2 line driver configurations (e.g., Figure 26 in datasheet), delivering 0.02% differential gain and 0.02° differential phase error at ±15 V. For best results, use a series output resistor (e.g., 75 Ω) to isolate capacitive load effects and match source impedance-ensuring minimal reflections on coaxial transmission lines.
What is the purpose of Pins 1 and 8 on THS4061ID?
Pins 1 and 8 are offset null terminals on THS4061ID. They allow adjustment of input offset voltage via an external potentiometer (e.g., 10 kΩ) connected between them, with the wiper tied to VCC−. This feature enables sub-millivolt DC accuracy in precision applications like medical sensor interfaces-though most video and high-speed uses operate within the specified 2.5–8 mV VOS without nulling.
Is THS4061ID pin-compatible with other packages in the THS406x family?
THS4061ID (SOIC-8) shares identical pinout with THS4061CD (commercial temp) and THS4061IDGN (HVSSOP-8), but the DGN package has different thermal and mechanical characteristics due to its PowerPAD®. Pin compatibility does not imply identical layout or thermal design-SOIC-8 requires standard JEDEC MS-012 footprint, while DGN demands thermal pad soldering and PCB copper pour for safe power dissipation.
