Product details
Overview
THS3062DR 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 THS3062DR datasheet, THS3062DR pinout, THS3062DR application, or THS3062DR equivalent, key selection criteria include its current-feedback architecture enabling stable high-gain bandwidth scaling, PowerPAD-enhanced thermal performance in SOIC-8 and MSOP-8 packages, and verified differential gain/phase performance for NTSC/PAL video line driving.
Technical Context
The THS3062DR implements a true current-feedback topology with separate high-impedance noninverting input and low-impedance inverting input, enabling bandwidth to be set primarily by feedback resistor value rather than closed-loop gain. Its BiCOM-I process supports ±15 V operation while maintaining 2.6 nV/√Hz input voltage noise and <0.3 dB peaking in unity-gain configuration.
Bandwidth scales inversely with feedback resistance: 220 MHz at G = 10 (Rf = 200 Ω), 275 MHz at G = 2 (Rf = 560 Ω), and 300 MHz at G = 1 (Rf = 750 Ω). Slew rate remains constant across output step size up to 20 V under ±15 V supply, with 1 ns rise/fall time and 30 ns 0.1% settling time for 2-V steps.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 300 MHz - Enables stable wideband amplification without phase-margin collapse at G = 1. |
| Slew Rate | 7000 V/μs - Supports full-scale 10-V output transitions in ≤1.4 ns, critical for pulse fidelity in test equipment. |
| 3rd-Harmonic Distortion | –81 dBc @ 10 MHz, G = 2, RL = 150 Ω - Meets broadcast video line-driver spectral purity requirements. |
| Output Current Drive | ±145 mA into 50 Ω - Directly drives twisted-pair telecom lines or back-terminated video loads without external buffers. |
| Supply Voltage Range | ±5 V to ±15 V - Compatible with legacy industrial ±12 V and high-dynamic-range ±15 V systems. |
| Input Voltage Noise | 2.6 nV/√Hz - Low enough to preserve SNR in high-gain preamplifier stages before 14-bit+ ADCs. |
| Differential Phase/Gain | 0.01° / 0.02% @ NTSC/PAL - Validated for composite video transmission without color shift or luminance error. |
Pinout & Package
THS3062DR is available in SOIC-8 (D) and MSOP-8 PowerPAD (DGN) packages. Both variants feature thermally enhanced underside copper pads requiring PCB thermal plane connection per TI SLMA002 guidelines. The SOIC-8 PowerPAD variant (DDA) offers lowest θJC (9.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1VOUT | Channel 1 output | Low-impedance current-output node; requires direct routing to load or termination to avoid instability. |
| 1VIN− | Channel 1 inverting input | Low-impedance (71 Ω) current-summing node; sets closed-loop gain via Rf to VOUT. |
| 1VIN+ | Channel 1 noninverting input | High-impedance (518 kΩ) voltage-input node; referenced to system ground or common-mode bias. |
| VS− | Negative supply rail | Must be decoupled with ≥0.1 µF ceramic + 10 µF tantalum near package; shared between both channels. |
| VS+ | Positive supply rail | Must be decoupled identically to VS−; total supply current is 2 × quiescent (max 12 mA/channel @ ±15 V). |
| 2VOUT | Channel 2 output | Independent output stage; electrically isolated from Channel 1 except via shared supply rails. |
| 2VIN− | Channel 2 inverting input | Identical electrical characteristics to 1VIN−; enables dual independent current-feedback paths. |
| 2VIN+ | Channel 2 noninverting input | Identical to 1VIN+; allows fully differential or single-ended dual-channel configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables bandwidth scaling with gain: 220 MHz at G = 10 vs. 300 MHz at G = 1, unlike voltage-feedback op-amps. |
| PowerPAD thermal enhancement | Reduces junction-to-case thermal resistance to 9.2°C/W (DDA) - essential for sustained ±145 mA output into 50 Ω. |
| Low distortion at high frequency | –81 dBc HD3 @ 10 MHz ensures clean spectral content in VDSL upstream band (up to 12 MHz) and video baseband. |
| High output current capability | ±145 mA sourcing/sinking eliminates need for external buffer stages in line-driver applications. |
| Wide supply range support | Operates from ±4.5 V to ±16.5 V absolute max - accommodates both low-power portable and high-dynamic-range instrumentation. |

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 |
|---|---|---|---|
| THS3092DR | Higher slew rate (8500 V/μs), lower distortion (–87 dBc HD3 @ 10 MHz), but higher quiescent current (13.5 mA/channel). | Better suited for repetitive sine-wave applications >900 V/μs where THS3062DR is not recommended per TI documentation. | Select THS3092DR when driving continuous high-frequency sinusoids or demanding RF IF stages; THS3062DR remains optimal for pulsed/line-driver use. |
| OPA691IDR | Lower slew rate (5500 V/μs), wider supply range (±5 V to ±6 V single-supply compatible), 350 mA output drive, but reduced bandwidth (280 MHz G = 1). | Preferred for low-voltage, high-current applications like portable ultrasound transducer drivers or battery-powered test gear. | Choose OPA691IDR when 350 mA sink/source into 25 Ω is required and ±15 V operation is unnecessary; THS3062DR excels in ±15 V, low-distortion video/VDSL roles. |
Compared with THS3062DR, THS3092DR provides superior harmonic suppression for continuous-wave signals but consumes more power, while OPA691IDR trades bandwidth and voltage range for extreme output current-making THS3062DR the balanced choice for ±15 V, low-distortion, dual-channel line driving.

FAQ
What is the maximum safe operating voltage for THS3062DR?
The THS3062DR has an absolute maximum supply voltage rating of ±16.5 V per the datasheet Absolute Maximum Ratings table. Continuous operation is specified from ±5 V to ±15 V, with thermal limits dictating practical upper bounds-especially in SOIC-8 (D) packages where power dissipation must stay below 410 mW at +85°C ambient. Exceeding ±16.5 V risks permanent damage.
Does THS3062DR support single-supply operation?
THS3062DR is explicitly designed for dual-supply operation (±5 V to ±15 V) and does not support true single-supply use. Its input common-mode range is limited to ±13.1 V at ±15 V supplies and ±3.1 V at ±5 V supplies-centered around ground-not the positive rail. For single-supply applications, TI recommends alternatives like OPA691 or THS3202 that specify rail-to-rail input/output and single-supply bias schemes.
How does THS3062DR's current-feedback architecture affect stability in gain-of-10 configurations?
In gain-of-10 configurations, THS3062DR requires Rf = 200 Ω (per Table 1 in the datasheet) to maintain 220 MHz bandwidth and adequate phase margin. Using higher Rf values causes bandwidth collapse and potential peaking or oscillation. Stability is ensured by adhering to TI-recommended feedback/gain resistor pairs and using 1% tolerance metal-film resistors placed close to the inverting input pins.
Can THS3062DR drive a 150-Ω load while maintaining NTSC video specifications?
Yes-THS3062DR is characterized for differential gain of 0.02% and differential phase of 0.01° into 150-Ω loads at NTSC frequencies, meeting broadcast video standards. This performance holds at G = 2, ±15 V supply, and Rf = 560 Ω. Load matching and proper termination are essential; the device's ±145 mA output ensures headroom even with multiple parallel 150-Ω loads.
What thermal considerations apply to THS3062DR in SOIC-8 PowerPAD (DDA) packaging?
The THS3062DR in SOIC-8 PowerPAD (DDA) package achieves θJC = 9.2°C/W, requiring connection of the exposed thermal pad to a dedicated PCB copper plane for effective heat transfer. Without this, junction temperature can exceed +125°C under full ±145 mA load, triggering thermal shutdown or accelerated aging. TI technical brief SLMA002 details minimum pad size, via count, and copper area requirements.
