Product details
Overview
THS3092DR from Texas Instruments is a dual-channel, high-voltage, low-distortion current-feedback operational amplifier designed for demanding wideband signal generation and driver applications. It delivers ±250 mA output current, 160 MHz small-signal bandwidth (G = 5, RL = 100 Ω), –66 dBc 2nd harmonic distortion at 10 MHz, and 5700 V/µs slew rate under ±15 V supply - enabling high-fidelity arbitrary waveform and Pin driver operation in test equipment and communications infrastructure.
For engineers reviewing the THS3092DR datasheet, THS3092DR pinout, THS3092DR application, or THS3092DR equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel CFB architecture, validated thermal performance with PowerPAD™, and real-world design context for high-voltage, low-THD analog signal paths requiring >±12 V swing into reactive loads.
Technical Context
The THS3092DR implements a current-feedback topology with separate high-impedance noninverting input and low-impedance inverting input, enabling gain-bandwidth independence and fast settling. Its transimpedance gain of 850 kΩ (±15 V) and 700 kΩ (±5 V) defines closed-loop response, while internal compensation ensures unity-gain stability across ±5 V to ±15 V supplies.
It features matched dual channels with <56 dB crosstalk at 10 MHz, common-mode input range of ±13.6 V (±15 V supply), and output stage optimized for driving capacitive and resistive loads up to 350 mA peak without oscillation - critical for VDSL line drivers and power FET gate control where large-signal fidelity and load tolerance are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±5 V to ±15 V - supports both industrial low-voltage and high-output swing systems without redesign. |
| Small-Signal Bandwidth | 160 MHz at G = 5, RL = 100 Ω - enables full-power response beyond 100 MHz for RF and video signal conditioning. |
| Slew Rate | 5700 V/µs (G = 5, VO = 20 VPP) - sustains linear large-signal transitions without slewing-induced distortion. |
| Harmonic Distortion | –66 dBc HD2 / –76 dBc HD3 at 10 MHz, RL = 100 Ω - meets stringent spectral purity requirements in arbitrary waveform generators. |
| Output Current | ±250 mA - drives heavy capacitive loads (e.g., cable, FET gates) while maintaining settling time <72 ns to 0.01%. |
| Input Noise | 2 nV/√Hz voltage noise + 13 pA/√Hz current noise - preserves SNR in high-gain, wideband front-end stages. |
| Package | SOIC-8 with PowerPAD™ - thermally enhanced for 2.18 W dissipation when PCB thermal plane is used. |
Pinout & Package
THS3092DR is housed in an 8-pin SOIC package with exposed PowerPAD™ on the underside, requiring connection to a copper thermal plane for rated power dissipation (2.18 W at TA ≤25°C). The PowerPAD™ is electrically isolated from all pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1VOUT | Channel 1 output | Delivers high-current, low-distortion output; requires local decoupling and layout symmetry for optimal transient response. |
| 1VIN− | Channel 1 inverting input | Low-impedance node; sets feedback path and gain; sensitive to trace inductance - must be short and direct. |
| 1VIN+ | Channel 1 noninverting input | High-impedance, low-capacitance (0.1 pF) node; referenced to ground or bias network for DC level setting. |
| VS− | Negative supply rail | Return path for both channels; must be low-inductance with dedicated ground plane and bulk + ceramic decoupling. |
| VS+ | Positive supply rail | Primary power input; shares decoupling with VS−; supports ±5 V to ±15 V operation without external regulation. |
| 2VOUT | Channel 2 output | Fully independent output; matched performance to Channel 1; enables dual-path signal generation or differential drive. |
| 2VIN− | Channel 2 inverting input | Electrically identical to 1VIN−; routing must mirror Channel 1 to minimize inter-channel skew and crosstalk. |
| 2VIN+ | Channel 2 noninverting input | Independent high-Z input; allows separate signal routing or common-mode biasing for balanced configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables stable gain ≥10 with flat bandwidth response and minimal peaking - unlike voltage-feedback op-amps. |
| PowerPAD™ thermal enhancement | Reduces ΘJA to 45.8°C/W, allowing 2.18 W continuous dissipation when soldered to 1-in² 2-oz Cu thermal pad. |
| High output voltage swing | ±12.5 V into 100 Ω (±15 V supply) - delivers full-scale signals to 50 Ω or 75 Ω systems without external level-shifting. |
| Low crosstalk | 60 dB (Ch1→Ch2) at 10 MHz - preserves channel isolation in dual DAC output buffering and I/Q signal paths. |
| Wide common-mode input range | ±13.6 V (±15 V supply) - accepts large-amplitude inputs directly, reducing need for attenuators or level translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-distortion amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3096DR | Dual-channel with integrated power-down pin (PD); quiescent current drops from 9.5 mA to 500 µA in standby. | Preferred in battery-powered or thermally constrained systems requiring dynamic power gating. | Select THS3096DR only if power-down functionality is required; pinout differs (14-pin TSSOP or SOIC-8), not drop-in compatible with THS3092DR. |
| THS4271DR | Single-channel, higher bandwidth (1.3 GHz small-signal), lower output current (±120 mA), no PowerPAD™. | Better suited for ultra-high-frequency, low-current gain blocks rather than high-current driver stages. | Choose THS4271DR for >500 MHz small-signal amplification; THS3092DR remains superior for >±12 V, >200 mA applications. |
Compared with THS3096DR and THS4271DR, the THS3092DR uniquely balances high output current (±250 mA), low distortion (–66 dBc), and SOIC-8 PowerPAD™ thermal capability - making it the only option among the three qualified for sustained high-voltage, high-fidelity driver operation without power-down or single-channel limitation.

FAQ
What is the maximum output voltage swing of the THS3092DR at ±15 V supply?
The THS3092DR delivers ±12.5 V into a 100 Ω load and ±13.2 V into a 1 kΩ load when operated at ±15 V supply. This high swing enables direct interfacing with 50 Ω or 75 Ω systems without external level-shifting circuitry, preserving signal integrity in high-fidelity driver applications.
Does the THS3092DR require external compensation for stability?
No - the THS3092DR is unity-gain stable and optimized for use with recommended feedback resistors (e.g., 715 Ω for G = 5). TI's datasheet provides validated RF/RG values per gain setting to ensure minimal peaking and maximum bandwidth without added compensation components.
Can the THS3092DR drive capacitive loads, and what is the recommended isolation resistor?
Yes, the THS3092DR can drive capacitive loads up to several hundred pF. For 100 pF loads, a 15 Ω series isolation resistor (RISO) is recommended; for 47 pF, 20 Ω is advised. These values maintain stability while minimizing degradation of transient response and settling time.
Is the PowerPAD™ on the THS3092DR electrically connected to any pin?
No - the PowerPAD™ on the THS3092DR is electrically isolated from all pins and must be soldered to a dedicated PCB thermal plane. Failure to connect it results in thermal derating: junction temperature may exceed 125°C, causing permanent performance degradation or device failure.
What is the typical harmonic distortion performance of the THS3092DR at 10 MHz?
At 10 MHz, the THS3092DR achieves –66 dBc 2nd harmonic distortion and –76 dBc 3rd harmonic distortion into a 100 Ω load with ±15 V supply. This performance is measured at G = 2, RF = 909 Ω, and VO = 2 VPP - confirming suitability for high-spectral-purity signal generation in THS3092DR-based designs.
