Product details
Overview
THS4061CDGN 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), 400 V/µs slew rate, and 40 ns settling time (0.1%), with ±5 V to ±15 V dual-supply operation and 115 mA output drive - enabling use in professional-grade 75 Ω video line drivers.
For engineers reviewing the THS4061CDGN datasheet, THS4061CDGN pinout, THS4061CDGN application, or THS4061CDGN equivalent, this page provides verified technical context, package-specific thermal design guidance, real-world video performance metrics (0.02% differential gain, 0.02° differential phase), and validated alternative options for high-fidelity analog signal path design.
Technical Context
The THS4061CDGN employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling wideband voltage-feedback architecture with unity-gain stability in both inverting and noninverting configurations. Its internal compensation targets minimum phase margin at G = +1 while preserving bandwidth and slew rate.
Designed for low-distortion, high-output-drive applications, it features integrated offset null pins (1 and 8), supports capacitive load isolation via series output resistors (≥20 Ω), and requires PowerPAD thermal connection to PCB ground 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 - enables baseband video and broadband IF signal amplification without gain peaking |
| Slew rate | 400 V/µs at ±15 V - supports fast transient response in pulse and composite video signals |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing-critical sampling and reconstruction requirements in digitizers |
| Differential gain/phase | 0.02% / 0.02° at NTSC, ±15 V - ensures broadcast-grade color fidelity in SD/HD video routing |
| Output current | 115 mA (typ) 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 supply - accommodates legacy ±5 V and high-dynamic-range ±15 V systems |
| Total harmonic distortion | −72 dBc at 1 MHz - maintains signal integrity in RF IF stages and precision test equipment |
Pinout & Package
HVSSOP-8 (DGN) package with exposed PowerPAD thermal pad on underside; requires solder connection to PCB thermal plane for rated power dissipation (2.14 W at TA ≤ 25°C). Pin 1 and Pin 8 are offset null terminals; Pin 4 is VCC−; Pin 7 is VCC+; Pin 6 is output; Pins 2 and 3 are inverting and noninverting inputs respectively.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null input - connect wiper of 10-kΩ potentiometer to VCC− for fine DC offset trimming |
| 2 | IN− | Inverting input - high-impedance node requiring shortest possible trace to minimize parasitic capacitance |
| 3 | IN+ | Noninverting input - referenced to system ground or common-mode bias; sensitive to layout asymmetry |
| 4 | VCC− | Negative supply rail - must be decoupled with 6.8 µF tantalum + 0.1 µF ceramic, placed ≤0.1 inch from pin |
| 5 | NC | No internal connection - electrically isolated; may be left unconnected or tied to ground for mechanical stability |
| 6 | OUT | Amplifier output - series resistor ≥20 Ω required for >10 pF capacitive loads to prevent ringing |
| 7 | VCC+ | Positive supply rail - identical decoupling requirement as Pin 4; shared decoupling not recommended |
| 8 | NULL | Offset null input - completes nulling circuit with Pin 1; floating connection degrades offset performance |
Key Features
| Feature | Design Value |
|---|---|
| PowerPAD thermal enhancement | Enables 2.14 W power dissipation at TA ≤ 25°C when soldered to 1-in² copper thermal plane - critical for sustained video line driving |
| Unity-gain stable | Operates without external compensation in G = +1 or G = −1 configurations - reduces BOM count and layout complexity |
| Low video distortion | 0.02% differential gain and 0.02° differential phase errors at NTSC 40 IRE - preserves chroma/luma timing in broadcast infrastructure |
| High output drive | 115 mA continuous output into 20 Ω - eliminates need for external buffer stages in multi-load video distribution |
| Offset null capability | Pins 1 and 8 support external 10-kΩ potentiometer - allows sub-mV DC offset correction 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 |
|---|---|---|---|
| THS4031CDGN | 100 MHz bandwidth, 220 V/µs slew rate, lower quiescent current (5.3 mA), no PowerPAD | Better suited for low-power portable video or battery-operated instrumentation where bandwidth ≤100 MHz suffices | Select THS4031CDGN only if 180 MHz bandwidth and 400 V/µs slew rate are not required - avoids over-spec'ing power and thermal design |
| LMH6702MA/NOPB | 1.6 GHz bandwidth, 3100 V/µs slew rate, higher supply current (12.5 mA), SOIC-8 only (no DGN) | Targeted at RF sampling and ultra-high-speed data converters where >500 MHz small-signal BW is mandatory | Choose LMH6702MA/NOPB only when THS4061CDGN's 180 MHz bandwidth is insufficient - requires redesign for higher supply current and layout sensitivity |
Compared with THS4061CDGN, THS4031CDGN trades bandwidth and drive strength for lower power and cost in mid-speed video, while LMH6702MA/NOPB delivers extreme speed at the expense of thermal management complexity and supply current - making THS4061CDGN the optimal balance for professional video and IF signal conditioning.

FAQ
What is the maximum power dissipation capability of the THS4061CDGN package?
The THS4061CDGN in HVSSOP-8 (DGN) package has a rated power dissipation of 2.14 W at TA ≤ 25°C, enabled by its PowerPAD thermal pad. This requires direct solder connection to a dedicated PCB copper thermal plane; failure to do so reduces effective power handling and risks junction temperature exceedance beyond 150°C.
Does the THS4061CDGN support single-supply operation?
Yes, the THS4061CDGN supports single-supply operation from 9 V to 32 V. When used in single-supply mode, the input common-mode range extends from 3.8 V to 4.3 V (at ±5 V equiv), and output swing reaches ±3.5 V into 1 kΩ - requiring proper input biasing and level-shifting networks for AC-coupled signal paths.
How does the THS4061CDGN achieve 0.02% differential gain in video applications?
The THS4061CDGN achieves 0.02% differential gain through precision bipolar transistor matching in its dielectrically isolated process, combined with optimized internal compensation that maintains flat group delay and minimal amplitude nonlinearity across 75 MHz. This is measured under NTSC 40 IRE modulation at ±15 V supply with gain = 2 configuration.
Can the THS4061CDGN drive a 75 Ω coaxial cable directly?
Yes, the THS4061CDGN can drive a 75 Ω coaxial cable directly when configured as a gain = 2 line driver with series output termination. A 75 Ω resistor placed between Pin 6 (OUT) and the cable ensures source-end impedance matching, suppresses reflections, and isolates capacitive loading - leveraging the device's 115 mA output current capability.
What is the purpose of Pins 1 and 8 on the THS4061CDGN?
Pins 1 and 8 on the THS4061CDGN are offset null terminals. Connecting a 10-kΩ potentiometer between them with its wiper tied to VCC− allows manual adjustment of input offset voltage down to sub-millivolt levels - essential for DC-coupled precision applications like medical sensor interfaces or calibration circuits where THS4061CDGN's typical 2.5–8 mV offset must be minimized.
