Product details

Overview

THS3062DRG4 from Texas Instruments is a dual-channel, high-voltage, current-feedback amplifier optimized for low-distortion, high-slew-rate signal conditioning. It delivers 7000 V/μs slew rate at ±15 V supply, 120 MHz 0.1-dB flat bandwidth (G = 2), –81 dBc 3rd harmonic distortion at 10 MHz, ±145 mA output drive into 50 Ω, and operates across ±5 V to ±15 V supplies. It is used in VDSL line drivers and high-voltage ADC preamplifiers requiring wide dynamic range and fast transient response.

For engineers reviewing the THS3062DRG4 datasheet, THS3062DRG4 pinout, THS3062DRG4 application, or THS3062DRG4 equivalent, key selection criteria include its current-feedback architecture enabling gain-independent bandwidth scaling, PowerPAD-enhanced thermal performance in SOIC-8 package, and verified video-grade differential gain (0.02%) and phase (0.01°) accuracy at NTSC/PAL frequencies.

Technical Context

The THS3062DRG4 employs a BiCOM-I complementary bipolar process with >3 GHz f_T transistors, enabling true current-feedback operation where bandwidth scales inversely with feedback resistor value-not closed-loop gain. Its transimpedance gain of 0.6–1 MΩ defines loop stability and noise trade-offs, while input resistance differs sharply between inverting (71 Ω) and noninverting (518 kΩ) terminals-critical for impedance matching in line-driver configurations.

Unlike voltage-feedback op-amps, THS3062DRG4's settling time (125 ns to 0.01% for 2-V step) and large-signal bandwidth (120 MHz at 4 V_PP) are decoupled from small-signal AC performance, allowing simultaneous optimization of speed and fidelity. Its ±13.7 V output swing into 1 kΩ at ±15 V supply and 0.3 dB peaking in unity-gain configuration confirm minimal phase margin degradation across frequency.

Key Specifications

Parameter	Value and Actual Design Meaning
Unity-Gain Bandwidth	300 MHz - Enables stable G = 1 operation with <0.3 dB peaking up to 100+ MHz, critical for video and baseband signal integrity.
Slew Rate	7000 V/μs at ±15 V - Supports clean 20-V-step reproduction within 3 ns, essential for pulsed high-fidelity instrumentation.
0.1-dB Flat Bandwidth	120 MHz (G = 2) - Guarantees amplitude accuracy ≤0.1 dB error across full video bandwidth (DC–120 MHz).
3rd Harmonic Distortion	–81 dBc at 10 MHz, G = 2, RL = 150 Ω - Meets broadcast-grade linearity requirements for analog video and DSL transmission.
Output Current Drive	±145 mA into 50 Ω - Directly drives twisted-pair telecom lines or 50-Ω test equipment without external buffers.
Supply Voltage Range	±5 V to ±15 V - Supports both low-power portable systems and high-voltage industrial signal chains with single-supply flexibility (10–30 V).
Input Voltage Noise	2.6 nV/√Hz above 10 kHz - Low enough to preserve SNR in 12-bit+ ADC front-ends with ≥10 MHz bandwidth.

Pinout & Package

THS3062DRG4 is packaged in an 8-pin SOIC with PowerPAD (DDA package), requiring thermal connection of the exposed pad to a PCB ground plane for safe operation at full output current. The PowerPAD reduces θ_JA to 45.8°C/W and enables 2.18 W continuous power dissipation at T_A ≤25°C.

Pin/Terminal	Circuit Role	Design Meaning
1VOUT	Channel 1 output	Low-impedance current-source output node; must be DC-coupled or AC-coupled via series capacitor depending on load biasing.
1VIN−	Channel 1 inverting input	71 Ω input resistance; connects to feedback network; sensitive to trace inductance-requires short, direct routing.
1VIN+	Channel 1 noninverting input	518 kΩ input resistance; high-impedance reference point; requires matched layout to minimize common-mode errors.
VS−	Negative supply rail	Must be bypassed with ≥0.1 µF ceramic + 10 µF tantalum near pin; shared return path impacts PSRR and crosstalk.
VS+	Positive supply rail	Same bypassing requirement as VS−; independent supply pins per channel not supported-dual channels share rails.
2VOUT	Channel 2 output	Electrically identical to 1VOUT; isolated output stage allows independent loading but shares thermal substrate.
2VIN−	Channel 2 inverting input	Identical 71 Ω impedance; layout symmetry with Channel 1 minimizes inter-channel crosstalk below –60 dB at 10 MHz.
2VIN+	Channel 2 noninverting input	Identical 518 kΩ impedance; no internal connection to Channel 1 inputs-true dual independent amplifier core.

Key Features

Feature	Design Value
Current-feedback architecture	Bandwidth remains stable across gains (220 MHz at G = 10) by adjusting R_f, enabling scalable design without topology change.
PowerPAD thermal enhancement	Reduces junction-to-ambient thermal resistance to 45.8°C/W, permitting ±145 mA sourcing/sinking at full ±15 V without derating.
Video-optimized linearity	Differential gain error 0.02% and phase error 0.01° at NTSC/PAL frequencies ensure broadcast-compliant color fidelity.
High-output-current capability	±145 mA into 50 Ω eliminates need for external buffer stages in DSL line drivers and RF test equipment interfaces.
Wide supply range support	Operates from ±5 V (6.3 mA/ch quiescent) to ±15 V (12 mA/ch max), simplifying integration into mixed-voltage system designs.

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 die, identical electrical specs; DDA package has lower θ_JA (45.8°C/W vs 97.5°C/W for DR) due to PowerPAD thermal pad soldered to PCB copper.	Preferred for high-power-density layouts or ambient temperatures >70°C where thermal headroom is constrained.	Select THS3062DDAR when board-level thermal management includes dedicated ground plane under PowerPAD; THS3062DRG4 suits standard SOIC footprints without thermal pad routing.
OPA691	Wider bandwidth (350 MHz unity-gain), higher output current (±350 mA), but higher distortion (–72 dBc 3rd HD @ 10 MHz) and no PowerPAD option in SOIC-8.	Better suited for RF IF amplification or laser diode drivers demanding >200 mA, less ideal for video-grade linearity.	Choose OPA691 only when peak output current >200 mA or bandwidth >250 MHz is mandatory; THS3062DRG4 remains superior for distortion-sensitive analog video and DSL.

Compared with THS3062DDAR, THS3062DRG4 trades 52°C/W higher thermal resistance for standard SOIC-8 assembly compatibility; compared with OPA691, it sacrifices 50 MHz bandwidth and 205 mA drive to achieve 9 dB lower 3rd-harmonic distortion and integrated thermal enhancement-making it optimal for precision line-driving where fidelity outweighs raw speed.

FAQ

What is the maximum safe operating voltage for THS3062DRG4?

The absolute maximum supply voltage for THS3062DRG4 is ±16.5 V, but the recommended operating range is ±5 V to ±15 V. Operation at ±16.5 V risks exceeding junction temperature limits unless thermal design accommodates 2.18 W dissipation. For reliable long-term use, TI specifies ±15 V as the maximum rated supply; THS3062DRG4 performance parameters-including slew rate and distortion-are fully characterized and guaranteed only within this range.

Does THS3062DRG4 require external compensation components?

No, THS3062DRG4 is internally compensated for unity-gain stability and does not require external capacitors or resistors for basic operation. Its current-feedback architecture relies on proper feedback resistor selection (e.g., 560 Ω for G = 2) rather than compensation networks. However, layout best practices-such as short traces to 1VIN−/2VIN−, ground-plane beneath PowerPAD, and local 0.1 µF + 10 µF supply bypassing-are mandatory to maintain specified bandwidth and distortion performance.

Can THS3062DRG4 drive a 75-Ω video load directly?

Yes, THS3062DRG4 can drive a 75-Ω load directly, delivering ±13 V output swing at ±15 V supply and maintaining –81 dBc 3rd harmonic distortion at 10 MHz. Its ±145 mA output current exceeds the 167 mA peak required for 2 V_PP into 75 Ω. For optimal video fidelity, use G = 2 configuration with R_f = 560 Ω and match source impedance to minimize reflections-THS3062DRG4's 0.02% differential gain error ensures broadcast-grade color accuracy.

How does THS3062DRG4 differ from THS3061 in pin compatibility and performance?

THS3062DRG4 is the dual-channel version of THS3061 (single-channel); both share identical per-channel specifications-same slew rate (7000 V/μs), bandwidth (300 MHz unity-gain), distortion (–81 dBc), and supply range (±5 V to ±15 V). Pinout differs: THS3062DRG4 uses an 8-pin SOIC with interleaved channels (1VOUT, 1VIN−, 1VIN+, VS−, VS+, 2VOUT, 2VIN−, 2VIN+), while THS3061 maps single-channel pins to same footprint. THS3062DRG4 enables space-efficient dual-path designs without doubling PCB area.

Is THS3062DRG4 suitable for repetitive high-slew-rate sine-wave applications?

No-TI explicitly advises against using THS3062DRG4 for repetitive signals exceeding 900 V/μs (e.g., high-frequency sine waves above ~1 MHz at large amplitudes) due to excessive power dissipation and risk of thermal runaway. It is optimized for pulsed or transient signals with ≥20 ns inter-pulse delay. For continuous high-slew-rate sine-wave generation, TI recommends THS3092 or THS3096-devices with enhanced thermal design and lower quiescent current at high frequencies.
