Product details
Overview
THS3092DRG4 from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier designed for high-fidelity, wideband signal amplification in demanding analog output stages. It delivers ±250 mA output drive, 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 precise arbitrary waveform generation and high-voltage line driving.
For engineers reviewing the THS3092DRG4 datasheet, THS3092DRG4 pinout, THS3092DRG4 application, or THS3092DRG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed dual-channel current-feedback architecture, validated thermal performance with PowerPAD™, and real-world design guidance for Pin driver, VDSL line driver, and high-speed DAC output buffering applications.
Technical Context
The THS3092DRG4 employs a current-feedback topology with separate high-impedance noninverting input and low-impedance inverting input, enabling stable wideband operation up to 160 MHz without gain-bandwidth trade-off. Its transimpedance gain of 850 kΩ (±15 V) and 700 kΩ (±5 V) defines closed-loop response when paired with external feedback resistors.
It operates across ±5 V to ±15 V dual supplies (or 10–30 V single supply), supports rail-to-rail output swing into 100 Ω (±12.5 V min), and maintains low distortion across temperature (–40°C to +85°C). The device lacks power-down functionality - distinguishing it from the THS3096 variant - and requires matched RF/RG resistor networks per channel for optimal flatness and stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW | 160 MHz at G = 5, RL = 100 Ω - enables full-power fidelity up to 100+ MHz signals in DAC reconstruction filters. |
| Slew rate | 5700 V/µs at G = 5, VO = 20 VPP - sustains clean large-swing transient response without slewing-induced distortion. |
| 2nd harmonic dist. | –66 dBc at 10 MHz, RL = 100 Ω - meets broadcast-grade video and precision test equipment spectral purity requirements. |
| Output current | ±250 mA - drives heavy capacitive loads (e.g., coaxial cables, piezo actuators) while maintaining settling time <72 ns (0.01%). |
| Supply range | ±5 V to ±15 V - supports legacy ±15 V instrumentation and modern ±5 V low-power systems without level-shifting. |
| Input noise | 2 nV/√Hz voltage noise + 13 pA/√Hz current noise - preserves SNR in high-gain, wideband sensor interface front-ends. |
| Common-mode range | ±13.6 V (min) at ±15 V supply - accommodates high-level AC-coupled inputs without clamping or attenuation. |
Pinout & Package
THS3092DRG4 is housed in an 8-pin SOIC package (D) with exposed PowerPAD™ thermal pad on the underside, requiring connection to a PCB copper plane for thermal management and reliable 1.02 W power dissipation at TA ≤ 25°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 output | High-current, low-impedance output node capable of ±250 mA sourcing/sinking into 40 Ω loads. |
| 2 | Channel 1 inverting input | Low-impedance (30 Ω) current-summing node; sets closed-loop gain via external RF resistor. |
| 3 | Channel 1 noninverting input | High-impedance (1.3 MΩ) input with 0.1 pF capacitance; used for DC biasing or signal reference. |
| 4 | Negative supply (VS−) | Return path for internal bias circuitry; must be decoupled locally with ≥10 µF + 0.1 µF ceramic. |
| 5 | Positive supply (VS+) | Primary power rail; supports ±5 V to ±15 V operation; requires symmetric decoupling to ground. |
| 6 | Channel 2 output | Independent high-drive output identical to Pin 1; enables dual-path signal conditioning or differential drive. |
| 7 | Channel 2 inverting input | Identical function to Pin 2; allows independent gain configuration per channel using separate RF/RG networks. |
| 8 | Channel 2 noninverting input | Identical function to Pin 3; supports individual DC offset control or common-mode referencing per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables constant bandwidth across gain settings - critical for programmable-gain DAC output stages. |
| PowerPAD™ thermal enhancement | Reduces ΘJA to 97.5°C/W (SOIC-D), allowing sustained 1.02 W dissipation without derating at 25°C ambient. |
| High-output-voltage swing | ±12.5 V into 100 Ω at ±15 V supply - eliminates need for external level-shifting in ±10 V analog I/O systems. |
| Low crosstalk | 60 dB (Ch1→Ch2) at 10 MHz - preserves channel isolation in dual-channel arbitrary waveform generators. |
| Wide supply flexibility | Operates from ±5 V to ±15 V or 10–30 V single supply - simplifies integration into mixed-voltage industrial and telecom platforms. |
Applications
| Arbitrary Waveform Generator Output Stage | VDSL Line Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, low-distortion operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Single-channel version with identical electrical specs (BW, slew, distortion, drive); same SOIC-8 package. | No dual-channel capability; requires two units for stereo or differential drive; higher board area and BOM count. | Select when only one high-performance channel is needed and space/cost optimization favors single-channel layout. |
| THS3202D | Higher slew rate (8000 V/µs), wider bandwidth (250 MHz), but higher distortion (–58 dBc HD2 @ 10 MHz) and no PowerPAD™. | Better for ultrafast pulse applications (e.g., laser diode drivers); less suitable for broadcast/video where distortion is critical. | Prefer for time-domain-critical systems needing faster edges; avoid where spectral purity dominates (e.g., comms test equipment). |
Compared with THS3092DRG4, THS3091DR offers identical per-channel performance in half the footprint but doubles component count for dual-channel use, while THS3202D trades distortion for speed - making THS3092DRG4 the optimal balance for high-fidelity, dual-channel, high-voltage analog output stages.

FAQ
What is the maximum output voltage swing of the THS3092DRG4 at ±15 V supply?
The THS3092DRG4 delivers a minimum output voltage swing of ±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 ±10 V industrial I/O standards without external level-shifting circuitry, and is validated across –40°C to +85°C operating temperature.
Does the THS3092DRG4 support single-supply operation?
Yes, the THS3092DRG4 supports single-supply operation from 10 V to 30 V. When biased appropriately (e.g., mid-rail input common-mode and output coupling), it maintains full AC performance including 160 MHz bandwidth and –66 dBc distortion. Refer to Figure 54 in the official datasheet for a validated DC-coupled single-supply schematic using THS3092DRG4.
What thermal considerations apply to the THS3092DRG4 SOIC-8 PowerPAD™ package?
The THS3092DRG4 in SOIC-8 (D) package features an exposed PowerPAD™ thermal pad that must be soldered to a dedicated PCB copper pour for effective heat dissipation. Without proper thermal connection, junction temperature may exceed 125°C - degrading distortion performance and reliability. TI recommends minimum 400 mm² copper area with ≥4 thermal vias to inner ground planes.
How does the THS3092DRG4 differ from the THS3096 in terms of functionality?
The THS3092DRG4 is the dual-channel, non-power-down variant; the THS3096 adds a dedicated power-down (PD) pin that reduces quiescent current from 9.5 mA to 500 µA. THS3092DRG4 has no PD pin and cannot enter standby mode - making it simpler for always-on applications but unsuitable where dynamic power gating is required.
Can the THS3092DRG4 drive capacitive loads, and what compensation is recommended?
Yes, the THS3092DRG4 can drive capacitive loads up to 100 pF with appropriate isolation resistance (RISO). TI specifies RISO = 15 Ω for CL = 100 pF (Figure 7). For larger loads, add series RISO between output and load, and verify stability using the recommended RISO vs. CL graph (Figure 8) - failure to compensate may cause peaking or oscillation in the 10–100 MHz band.
