Product details
Overview
THS4061IDGNR from Texas Instruments is a single-channel, high-speed voltage-feedback operational amplifier optimized for professional video, imaging, and broadband signal conditioning. It delivers 180 MHz small-signal bandwidth (G = 1), 400 V/µs slew rate, 40 ns settling time to 0.1%, ±11.5 V output swing into 250 Ω, and 0.02% differential gain error - enabling precision analog signal distribution in broadcast-grade video line drivers.
For engineers reviewing the THS4061IDGNR datasheet, THS4061IDGNR pinout, THS4061IDGNR application, or THS4061IDGNR equivalent, this page provides verified technical context, package-specific pin mapping, real-world video and instrumentation use cases, and validated alternative options for design-in continuity and supply chain resilience.
Technical Context
The THS4061IDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wideband voltage-feedback operation without external compensation. Its internal frequency compensation ensures stability at all gains in both inverting and noninverting configurations, including unity-gain.
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 robust 115 mA output drive capability. The DGN package integrates PowerPAD™ thermal enhancement, requiring connection to a PCB thermal plane for rated 2.14 W dissipation at TA ≤ 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−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 >100 MHz square waves with minimal edge distortion |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing-critical sampling and multiplexing requirements in data acquisition systems |
| Differential gain/phase | 0.02% / 0.02° at NTSC, G = 2, ±15 V - preserves color fidelity in analog video transmission paths |
| Output current (IO) | 115 mA typical into 20 Ω - drives multiple 75-Ω video loads or low-impedance ADC inputs directly |
| Supply range | ±4.5 V to ±16.5 V dual or 9 V to 33 V single - accommodates industrial, test equipment, and legacy video rails |
| THD @ 1 MHz | −72 dBc - ensures low spurious content in RF IF stages and high-fidelity signal generation |
Pinout & Package
The THS4061IDGNR is housed in an 8-pin HVSSOP (DGN) package with exposed PowerPAD™ thermal pad on the underside. This thermally enhanced MSOP variant requires soldering the pad to a dedicated copper pour for safe power dissipation up to 2.14 W at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Inverting input offset null terminal - connect wiper of 10-kΩ potentiometer to VCC− for fine trim |
| 2 | IN− | Inverting input - high-impedance node with 2 pF capacitance; keep trace short to minimize instability |
| 3 | IN+ | Noninverting input - referenced to common-mode range of ±13.8 V at ±15 V supplies |
| 4 | VCC− | Negative supply rail - decouple with 0.1 µF ceramic + 6.8 µF tantalum close to pin |
| 5 | NC | No internal connection - leave unconnected; not bonded or functional |
| 6 | OUT | Amplifier output - capable of ±11.5 V swing into 250 Ω; series 20–75 Ω resistor recommended for >10 pF capacitive loads |
| 7 | VCC+ | Positive supply rail - same decoupling requirement as VCC−; avoid shared traces with digital supplies |
| 8 | NULL | Noninverting input offset null terminal - connect opposite end of same potentiometer to VCC+ |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | Internally compensated for unconditional stability in inverting/noninverting configurations - eliminates need for external compensation networks |
| PowerPAD™ thermal management | Exposed thermal pad enables 2.14 W power dissipation at TA ≤ 25°C when connected to ≥1 in² 2-oz copper plane - critical for sustained video line driving |
| Low video distortion | 0.02% differential gain and 0.02° differential phase at NTSC 40 IRE - maintains broadcast-level color accuracy without post-correction |
| High output drive | 115 mA continuous output current - drives four 75-Ω video loads simultaneously or interfaces directly with low-Z ADC front-ends |
| Wide supply flexibility | Operates from ±4.5 V to ±16.5 V dual or 9–33 V single supply - supports portable, industrial, and legacy rack-mounted equipment designs |

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 |
|---|---|---|---|
| THS3201CDGNR | Higher 1.8-GHz bandwidth but lower 70-mA output drive; no offset null pins; 12-V max supply | Better suited for RF gain blocks above 100 MHz; unsuitable for multi-load video driving or ±15-V systems | Select THS3201CDGNR only when bandwidth >500 MHz is required and load current <70 mA |
| LMH6702MA/NOPB | 1.7-GHz bandwidth, 120 mA output, but higher 17 nV/√Hz input noise vs. THS4061IDGNR's 14.5 nV/√Hz; no null pins | Preferred for ultra-wideband IF amplification; lacks video-optimized differential gain/phase specs | Choose LMH6702MA/NOPB for >500-MHz small-signal gain; retain THS4061IDGNR for video fidelity or offset trim needs |
Compared with THS3201CDGNR and LMH6702MA/NOPB, the THS4061IDGNR uniquely balances 180-MHz bandwidth, 115-mA drive, 0.02% video linearity, and offset nulling - making it the optimal choice for cost-sensitive, multi-load analog video and precision instrumentation where stability and color fidelity are non-negotiable.

FAQ
What is the operating temperature range for the THS4061IDGNR?
The THS4061IDGNR is rated for industrial operation from −40°C to +85°C, as indicated by the "I" suffix in its part number. This range is validated across all key specifications including bandwidth, slew rate, and differential gain/phase error - ensuring consistent performance in outdoor video enclosures, factory-floor test gear, and medical diagnostic equipment.
Does the THS4061IDGNR require external compensation for unity-gain stability?
No, the THS4061IDGNR is internally compensated and unconditionally stable at all closed-loop gains, including unity-gain in both inverting and noninverting configurations. Its compensation network is optimized for maximum bandwidth while maintaining ≥45° phase margin - eliminating the need for external capacitors or feedback adjustments in standard applications.
How should the PowerPAD™ thermal pad on the THS4061IDGNR be connected?
The exposed PowerPAD™ on the THS4061IDGNR must be soldered to a dedicated thermal copper plane on the PCB, ideally ≥1 in² of 2-oz copper. This connection is mandatory to achieve the rated 2.14 W power dissipation at TA ≤ 25°C. Failure to thermally connect the pad risks junction temperature exceeding 150°C, leading to permanent device failure under sustained load.
Can the THS4061IDGNR drive multiple 75-Ω video loads simultaneously?
Yes - the THS4061IDGNR delivers 115 mA typical output current and maintains 0.02% differential gain error even when driving up to four 75-Ω loads in parallel (as confirmed in Figure 6 of the datasheet). For reliable operation, use a series 75-Ω resistor at the output to isolate cable capacitance and preserve impedance matching.
What is the purpose of Pins 1 and 8 (NULL) on the THS4061IDGNR?
Pins 1 and 8 are offset null terminals that allow fine adjustment of input offset voltage using an external 10-kΩ potentiometer. Connect the potentiometer ends to Pins 1 and 8, and tie the wiper to VCC−. This feature is especially valuable in DC-coupled video systems or precision instrumentation where sub-millivolt offset must be eliminated without adding external correction circuitry.
