Product details
Overview
THS3062DDARG3 from Texas Instruments is a dual-channel, 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 (±15 V), 300 MHz unity-gain bandwidth, –81 dBc 3rd-harmonic distortion at 10 MHz (G = 2, RL = 150 Ω), ±145 mA output drive into 50 Ω, and operates from ±5 V to ±15 V supplies.
For engineers reviewing the THS3062DDARG3 datasheet, THS3062DDARG3 pinout, THS3062DDARG3 application, or THS3062DDARG3 equivalent, this page provides verified electrical specifications, SOIC-8 PowerPAD package details, dual-channel pin mapping, real-world harmonic distortion vs frequency curves, and validated alternatives for high-fidelity analog signal path design.
Technical Context
The THS3062DDARG3 uses Texas Instruments' BiCOM-I dielectrically isolated complementary bipolar process to achieve high fT transistors enabling its 300 MHz unity-gain bandwidth and 7000 V/μs slew rate. Its current-feedback architecture allows bandwidth scaling with gain via feedback resistor selection (e.g., 560 Ω for G = 2, 200 Ω for G = 10).
It features matched input resistances (518 kΩ noninverting, 71 Ω inverting), low input capacitance (1 pF), and maintains <0.3 dB peaking in unity gain. Thermal performance relies on PowerPAD soldering to PCB copper for θJA = 45.8°C/W (DDA package) and continuous operation up to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 300 MHz - Enables stable wideband amplification up to 100+ MHz with minimal phase margin loss. |
| Slew Rate | 7000 V/μs at ±15 V - Supports clean 10-MHz, 2-VPP sine wave reproduction without slewing-induced distortion. |
| 3rd Harmonic Distortion | –81 dBc @ 10 MHz, G = 2, RL = 150 Ω - Meets broadcast-grade video line driver spectral purity requirements. |
| Output Current Drive | ±145 mA into 50 Ω - Sufficient to drive twisted-pair VDSL lines or multiple 150-Ω video loads simultaneously. |
| Supply Voltage Range | ±5 V to ±15 V - Compatible with industrial and instrumentation rails; supports ±12 V legacy systems. |
| Input Offset Voltage | ±4.5 mV max over temperature - Ensures DC accuracy in precision gain stages without external trimming. |
| Quiescent Current per Channel | 12 mA max at +85°C - Balances speed and power for dual-channel high-performance analog front ends. |
Pinout & Package
THS3062DDARG3 is housed in an 8-pin SOIC package with PowerPAD (DDA variant), requiring thermal pad soldering to PCB ground plane for safe operation at full output current. The PowerPAD is electrically isolated from all pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1VOUT | Channel 1 output - Drives load directly; requires proper termination to avoid instability. |
| 2 | 1VIN− | Inverting input - Low impedance (71 Ω); sets feedback node in current-feedback configuration. |
| 3 | 1VIN+ | Noninverting input - High impedance (518 kΩ); used for signal reference or differential input biasing. |
| 4 | VS− | Negative supply rail - Must be decoupled with 0.1 µF + 10 µF capacitors near pin. |
| 5 | VS+ | Positive supply rail - Same decoupling requirement as VS−; enables ±15 V operation. |
| 6 | 2VOUT | Channel 2 output - Independent of Channel 1; supports dual-path signal processing. |
| 7 | 2VIN− | Channel 2 inverting input - Matches Channel 1 characteristics; enables identical gain configurations. |
| 8 | 2VIN+ | Channel 2 noninverting input - Electrically identical to Pin 3; supports fully differential or single-ended use. |
Key Features

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 |
|---|---|---|---|
| THS3062D | No PowerPAD; θJA = 97.5°C/W; max output current derated to ±130 mA at +85°C. | Suitable only for lower-power, single-channel or intermittent-duty use; not recommended for continuous 145-mA loads. | Select THS3062D only when thermal budget permits and PCB lacks PowerPAD layout capability. |
| OPA691 | Higher quiescent current (12.5 mA/channel); 350 mA output drive; 350 MHz GBW; no PowerPAD option. | Better suited for ultra-high-current applications (e.g., driving 25-Ω RF loads), but higher power dissipation limits dual-channel density. | Choose OPA691 when >200 mA output is required and thermal management via heatsink is feasible. |
Compared with THS3062D and OPA691, THS3062DDARG3 uniquely balances 145 mA drive, 7000 V/μs slew rate, and PowerPAD-enabled thermal reliability in a space-constrained dual-channel SOIC footprint-making it optimal for embedded video and broadband line driver designs where board area and thermal headroom are constrained.

FAQ
What is the maximum safe operating voltage for THS3062DDARG3?
The THS3062DDARG3 has an absolute maximum supply voltage rating of ±16.5 V, but its specified operating range is ±5 V to ±15 V. Operation at ±16.5 V exceeds recommended conditions and risks permanent damage due to internal junction stress. For reliable long-term use, maintain supply within ±15 V, especially under full output load and elevated ambient temperatures.
Does THS3062DDARG3 require external compensation for stability?
No, THS3062DDARG3 is internally compensated for unity-gain stability and exhibits <0.3 dB peaking in G = 1 configuration. Stability is maintained using recommended feedback resistors (e.g., 750 Ω for G = 1, 560 Ω for G = 2). Deviating significantly from these values-especially using lower RF-may degrade phase margin and cause ringing or oscillation.
Can THS3062DDARG3 drive a 75-Ω video load directly?
Yes, THS3062DDARG3 can drive a 75-Ω load directly with full 2-VPP output swing and –82 dBc 3rd harmonic distortion at 10 MHz. However, for optimal video performance, use series 75-Ω termination at the amplifier output and ensure proper PCB layout with controlled impedance traces and tight ground return paths to preserve differential phase/gain specs.
How does the PowerPAD on THS3062DDARG3 affect thermal design?
The PowerPAD on THS3062DDARG3 must be soldered to a thermally robust PCB copper plane to achieve its rated θJA = 45.8°C/W. Without this connection, junction temperature rises rapidly-potentially exceeding +125°C during 145-mA output events. TI technical brief SLMA002 specifies minimum copper area (≥3 in²) and via count (≥6 × 0.3-mm vias) for safe operation at full specification.
Is THS3062DDARG3 suitable for repetitive high-slew-rate signals?
No-THS3062DDARG3 is not recommended for repetitive signals exceeding 900 V/μs (e.g., continuous 10-MHz square waves), as this causes excessive supply current draw and possible device damage. It is optimized for pulsed or large-signal transient applications with ≥20-ns inter-pulse delay. For repetitive high-slew signals, TI recommends THS3092 or THS3096 instead.
