Product details
Overview
THS3062DGNG4 from Texas Instruments is a dual high-voltage, current-feedback amplifier optimized for low-distortion, high-slew-rate signal conditioning in video, VDSL, and high-speed ADC driver applications. It delivers 7000 V/μs slew rate at ±15 V supply, 300 MHz unity-gain bandwidth, –81 dBc third-harmonic distortion at 10 MHz (G = 2, RL = 150 Ω), and ±145 mA output drive into 50 Ω.
For engineers reviewing the THS3062DGNG4 datasheet, THS3062DGNG4 pinout, THS3062DGNG4 application, or THS3062DGNG4 equivalent, key selection criteria include its current-feedback architecture enabling stable high-gain bandwidth scaling, PowerPAD-enhanced thermal performance in MSOP-8, and verified differential gain/phase accuracy for NTSC/PAL video systems.
Technical Context
The THS3062DGNG4 employs a BiCOM-1 complementary bipolar process with dielectric isolation, supporting ±4.5 V to ±16.5 V supplies. Its current-feedback topology uses separate high-impedance noninverting input and low-impedance inverting input, enabling bandwidth control via feedback resistor (Rf) selection-e.g., 560 Ω for G = 2, 357 Ω for G = 5-while maintaining < 0.3 dB peaking.
It features 2.6 nV/√Hz input voltage noise, 20 pA/√Hz noninverting input current noise, and achieves 0.02% differential gain / 0.01° differential phase at G = 2 with 150 Ω loads-critical for broadcast-quality video line driving. Thermal design requires soldering the exposed PowerPAD to a copper plane per TI SLMA002 guidelines.
Key Specifications

| Differential Phase | 0.01° (NTSC/PAL, G = 2) - ensures color fidelity in analog video distribution systems. |
Pinout & Package
The THS3062DGNG4 is housed in an 8-pin MSOP package with PowerPAD (DGN), requiring thermal connection of the exposed pad to PCB ground or power plane for safe operation at full output current.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1VOUT | Channel 1 output | Delivers amplified signal; capable of ±145 mA sink/source into 50 Ω with < 0.3 dB peaking up to 300 MHz. |
| 1VIN− | Channel 1 inverting input | Low-impedance node (71 Ω typ); sets closed-loop gain with Rf and determines bandwidth via Rf value. |
| 1VIN+ | Channel 1 noninverting input | High-impedance node (518 kΩ typ); provides reference for differential input; common-mode range ±13.9 V at ±15 V supply. |
| VS− | Negative supply rail | Accepts –4.5 V to –16.5 V; PSRR of 74 dB minimizes noise coupling from negative rail. |
| VS+ | Positive supply rail | Accepts +4.5 V to +16.5 V; PSRR of 76 dB ensures clean output under supply ripple. |
| 2VIN− | Channel 2 inverting input | Independent low-Z input identical to Pin 2; enables dual-channel differential line driving. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3062DDAR | Same silicon die in SOIC-8 PowerPAD (DDA) package; θJC = 9.2 °C/W vs. 4.7 °C/W for DGN; higher thermal resistance limits continuous 145 mA output at elevated ambient. | Preferred for legacy SOIC footprints where board rework is prohibitive; unsuitable for compact, thermally constrained layouts. | Select THS3062DDAR only when MSOP-8 assembly is unavailable; verify thermal derating curves for target ambient temperature. |
| THS3122DGNR | Higher output current (±350 mA), lower slew rate (4100 V/μs), wider supply range (±18 V); 3rd-harmonic distortion –72 dBc at 10 MHz-10 dB worse than THS3062DGNG4. | Better suited for high-current pulse applications (e.g., laser diode drivers); less suitable for low-distortion video or broadband comms. | Choose THS3122DGNR when peak current > ±200 mA is required; accept trade-off in distortion performance for drive strength. |
Compared with THS3062DGNG4, THS3062DDAR offers identical electrical specs but reduced thermal efficiency in SOIC packaging, while THS3122DGNR trades distortion performance for higher output current-making THS3062DGNG4 optimal for bandwidth/distortion-critical video and VDSL line driving.

FAQ
What is the maximum safe operating voltage for THS3062DGNG4?
The THS3062DGNG4 has an absolute maximum supply voltage rating of ±16.5 V. Operation beyond this risks permanent damage. For reliable long-term use, TI specifies ±15 V as the recommended maximum operating voltage. At ±15 V, the device delivers full 7000 V/μs slew rate and ±145 mA output current while maintaining < 0.3 dB peaking in frequency response. Derating is required above +85°C ambient.
Does THS3062DGNG4 require external compensation components?
No, THS3062DGNG4 is internally compensated for unity-gain stability and does not require external capacitors. Its current-feedback architecture relies on precise feedback resistor (Rf) selection to set bandwidth-e.g., 560 Ω for G = 2, 357 Ω for G = 5-rather than compensation networks. Using 1% tolerance metal-film resistors is recommended to maintain specified bandwidth and phase margin.
Can THS3062DGNG4 drive a 75 Ω video load directly?
Yes, THS3062DGNG4 can drive a 75 Ω video load directly with full performance. At ±15 V supply, it delivers ±13 V output swing into 150 Ω (dual 75 Ω in parallel) and maintains 0.02% differential gain / 0.01° differential phase-meeting SMPTE 253M broadcast standards. For single 75 Ω loads, output swing remains > ±12.6 V with < 0.3 dB flatness to 120 MHz.
How does the PowerPAD on THS3062DGNG4 affect thermal design?
THS3062DGNG4's exposed PowerPAD (Pin 9, internal thermal pad) must be soldered to a dedicated PCB copper plane for thermal conduction. With proper 2 oz. copper connection, θJC drops to 4.7 °C/W, enabling continuous ±145 mA output into 50 Ω at +85°C ambient. Omitting pad connection raises junction temperature by > 40°C under full load, risking thermal shutdown or accelerated parametric drift.
Is THS3062DGNG4 suitable for single-supply operation?
THS3062DGNG4 supports single-supply operation from 10 V to 30 V, but its input common-mode range is limited to within ~1.5 V of each rail. At +12 V single supply, the usable input range is approximately 1.5 V to 10.5 V. For true rail-to-rail input capability or low-voltage operation (< 10 V), alternative amplifiers like the OPA691 or THS3112 should be evaluated.
