Product details
Overview
THS3062DGNRG4 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 fast, linear large-signal response.
For engineers reviewing the THS3062DGNRG4 datasheet, THS3062DGNRG4 pinout, THS3062DGNRG4 application, or THS3062DGNRG4 equivalent, key selection criteria include slew rate vs. output step performance, harmonic distortion at 10 MHz under 150 Ω load, thermal management of the MSOP-8 PowerPAD™ package, and feedback resistor optimization for gain stability and noise.
Technical Context
The THS3062DGNRG4 employs a current-feedback architecture with BiCOM-1 bipolar process, enabling wide bandwidth independent of closed-loop gain-e.g., 220 MHz (–3 dB) at G = 10 with Rf = 200 Ω. Its transimpedance gain is 0.6–1 MΩ, and input impedance differs sharply between inverting (71 Ω) and noninverting (518 kΩ) terminals, defining its current-sensing node behavior.
It features thermally enhanced MSOP-8 PowerPAD™ packaging with θJA = 58.4°C/W and requires PCB copper plane connection to the exposed pad for safe operation at full ±15 V/±145 mA output. The device exhibits <0.3 dB peaking in unity-gain configuration and maintains 0.01° differential phase accuracy for video applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±15 V - supports industrial and telecom rails; absolute max ±16.5 V prevents latch-up. |
| Slew Rate | 7000 V/μs (G = 5, ±15 V) - enables clean 20-V-step reproduction without slewing artifacts in pulse amplification. |
| 0.1-dB Bandwidth | 120 MHz (G = 2, ±15 V) - ensures flat frequency response up to 120 MHz for broadband signal integrity. |
| 3rd Harmonic Distortion | –81 dBc @ 10 MHz, G = 2, RL = 150 Ω - meets stringent spectral purity requirements in VDSL and video line driving. |
| Output Current | ±145 mA into 50 Ω - drives twisted-pair lines or multiple 150 Ω video loads without external buffers. |
| Input Voltage Noise | 2.6 nV/√Hz (>10 kHz) - low enough to preserve SNR in high-gain ADC front-ends with ≥100 kHz bandwidth. |
| Quiescent Current | 8.3 mA per channel (±15 V) - balances speed and power efficiency for dual-channel high-speed systems. |
Pinout & Package
THS3062DGNRG4 is housed in an 8-pin MSOP PowerPAD™ (DGN) package with thermally enhanced exposed die paddle. The PowerPAD must be soldered to a PCB copper plane for thermal conduction; it is electrically isolated from all pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VOUT1) | Channel 1 output | High-current, low-impedance output node; connects directly to load or termination network. |
| 2 (VIN−1) | Channel 1 inverting input | Low-impedance (~71 Ω) current-summing node; sets feedback path and gain with Rf. |
| 3 (VIN+1) | Channel 1 noninverting input | High-impedance (~518 kΩ) voltage reference node; used for DC biasing or signal injection. |
| 4 (V−) | Negative supply rail | Connects to system ground or negative supply; decoupling capacitor required near pin. |
| 5 (V+) | Positive supply rail | Connects to system positive supply; decoupling capacitor required near pin. |
| 6 (VOUT2) | Channel 2 output | Independent high-drive output; enables dual-path signal processing (e.g., differential line driver). |
| 7 (VIN−2) | Channel 2 inverting input | Current-summing node for second channel; allows separate gain configuration from Channel 1. |
| 8 (VIN+2) | Channel 2 noninverting input | High-Z reference for second channel; supports independent DC offset or common-mode control. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables gain-independent bandwidth scaling-e.g., 220 MHz at G = 10-without sacrificing stability. |
| PowerPAD™ thermal package | Reduces θJA to 58.4°C/W, allowing safe ±15 V operation with 145 mA output in compact MSOP-8 footprint. |
| Low 3rd-harmonic distortion | –81 dBc at 10 MHz ensures minimal intermodulation in multi-tone VDSL and CATV upstream signals. |
| Differential phase/gain accuracy | 0.01° / 0.02% (NTSC/PAL) enables broadcast-grade video line driving without color fidelity loss. |
| Wide supply range | ±5 V to ±15 V operation supports both low-power instrumentation and high-voltage test equipment 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 | SOIC-8 PowerPAD™ package (θJA = 45.8°C/W); same electrical specs but larger footprint and higher thermal resistance. | Better suited for prototyping or lower-power dual-channel use where MSOP layout density is not critical. | Select THS3062DDAR when board space permits and thermal margin is sufficient at ≤100 mA continuous output. |
| THS3122DGNR | Higher output current (±350 mA), wider bandwidth (220 MHz @ G = 2), but higher quiescent current (12.5 mA/ch) and no 0.1-dB flatness spec. | Targeted at demanding line drivers needing >200 mA drive, e.g., long-reach xDSL or active antenna systems. | Choose THS3122DGNR only when THS3062DGNRG4's 145 mA output is insufficient and extra power dissipation is acceptable. |
Compared with THS3062DDAR, THS3062DGNRG4 offers 23% lower thermal resistance in MSOP-8 PowerPAD™, enabling higher sustained output current in space-constrained layouts; versus THS3122DGNR, it trades peak drive capability for lower power and tighter distortion specs at 10 MHz.

FAQ
What is the maximum safe operating voltage for THS3062DGNRG4?
The THS3062DGNRG4 has an absolute maximum supply voltage rating of ±16.5 V, but its recommended operating range is ±5 V to ±15 V. Operation at ±15 V is fully characterized and supported across temperature; exceeding ±16.5 V risks permanent damage due to junction breakdown. Always observe derating curves in the datasheet for extended lifetime reliability.
Can THS3062DGNRG4 drive a 150 Ω load at 10 MHz with low distortion?
Yes. At G = 2, ±15 V supply, and RL = 150 Ω, THS3062DGNRG4 achieves –81 dBc 3rd harmonic distortion at 10 MHz, meeting stringent spectral purity requirements for VDSL and video applications. This performance is verified in the official TI SLOS394B datasheet under standard test conditions.
Is the PowerPAD™ on THS3062DGNRG4 electrically connected to any pin?
No. The PowerPAD™ on THS3062DGNRG4 is electrically isolated from all eight signal pins and must be connected solely to a PCB thermal plane (e.g., ground or dedicated copper pour) via solder. TI documentation explicitly states it is "electrically isolated from all other pins" and serves only thermal conduction-not electrical functionality.
What feedback resistor value is recommended for THS3062DGNRG4 at G = 2 and ±15 V supply?
Texas Instruments specifies 560 Ω as the recommended feedback resistor (Rf) for THS3062DGNRG4 at G = 2 and ±15 V supply. This value balances bandwidth (275 MHz small-signal), phase margin, and distortion (–81 dBc HD3). Using 1% tolerance resistors is mandatory to maintain gain accuracy and stability per the datasheet Application Information section.
How does THS3062DGNRG4 compare to THS3061 in terms of channel count and package options?
THS3062DGNRG4 is the dual-channel variant, while THS3061 is single-channel. Both share identical electrical specifications, but THS3062DGNRG4 is offered exclusively in MSOP-8 PowerPAD™ (DGN) and SOIC-8 PowerPAD™ (DDA) packages-no standard SOIC option. THS3061 adds standard SOIC-8 (D) and MSOP-8 PowerPAD™ (DGN) variants, giving it broader packaging flexibility.
