Product details
Overview
THS3092DDAG4 from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier designed for high-fidelity 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 high-voltage arbitrary waveform generation in test equipment and line drivers.
For engineers reviewing the THS3092DDAG4 datasheet, THS3092DDAG4 pinout, THS3092DDAG4 application, or THS3092DDAG4 equivalent, this page provides verified electrical specifications, SOIC-8 PowerPAD™ package details, dual-channel current-feedback architecture context, and validated alternatives for high-speed, low-distortion driver replacement scenarios.
Technical Context
The THS3092DDAG4 implements a current-feedback topology with separate high-impedance noninverting input (1.3 MΩ) and low-impedance inverting input (30 Ω), enabling wide bandwidth independent of closed-loop gain. Its transimpedance gain exceeds 850 kΩ at ±15 V, supporting fast settling (42 ns to 0.1%) and stable operation with capacitive loads up to 100 pF when using recommended RISO compensation.
It operates across ±5 V to ±15 V dual supplies (or 10–30 V single supply), with rail-to-rail output swing capability (±12.5 V into 100 Ω) and integrated thermal protection via PowerPAD™. Unlike voltage-feedback op-amps, its bandwidth remains flat across gains of 1–10 due to fixed feedback resistor optimization (e.g., 715 Ω for G = 5).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 160 MHz at G = 5, RL = 100 Ω - enables full-power response beyond 100 MHz for RF and video applications |
| Slew rate | 5700 V/µs at G = 5, VO = 20 VPP - supports clean 20-VPP sine waves up to ~10 MHz without slewing artifacts |
| 2nd harmonic distortion | −66 dBc at 10 MHz, RL = 100 Ω - ensures <0.05% THD for precision waveform synthesis and broadcast-grade video |
| Output current drive | ±250 mA - drives heavy loads including 40-Ω power FET gates and multi-load VDSL line interfaces |
| Input voltage noise | 2 nV/√Hz above 10 kHz - preserves SNR in high-gain, wideband front-end stages |
| Supply range | ±5 V to ±15 V - accommodates legacy ±12 V and modern ±15 V systems without level-shifting |
| Quiescent current | 9.5 mA per channel - balances speed and power efficiency for continuous high-output operation |
Pinout & Package
THS3092DDAG4 is housed in an 8-pin SOIC package with PowerPAD™ thermal enhancement (DDA suffix). The exposed thermal pad on the underside must be soldered to a PCB copper plane for reliable thermal dissipation; it is electrically isolated from all pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1VOUT | Channel 1 output | Delivers amplified signal; capable of ±12.5 V swing into 100 Ω with 250 mA sourcing/sinking |
| 1VIN− | Channel 1 inverting input | Low-impedance node (30 Ω); sets feedback path and gain with external RF resistor |
| 1VIN+ | Channel 1 noninverting input | High-impedance node (1.3 MΩ); used for signal injection in noninverting configurations |
| VS− | Negative supply rail | Accepts −5 V to −15 V; must be decoupled with ≥0.1 µF ceramic capacitor near pin |
| VS+ | Positive supply rail | Accepts +5 V to +15 V; requires local 0.1 µF + 6.8 µF bulk capacitance for stability |
| 2VOUT | Channel 2 output | Independent output identical to Pin 1; enables dual-path signal conditioning or differential drive |
| 2VIN− | Channel 2 inverting input | Matches Pin 2 behavior; supports independent gain setting per channel |
| 2VIN+ | Channel 2 noninverting input | Matches Pin 3 behavior; allows separate signal routing for each amplifier |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables constant 160-MHz bandwidth across gains of 1–10, unlike voltage-feedback op-amps whose bandwidth drops with gain |
| PowerPAD™ thermal package | Reduces θJA to 45.8°C/W (vs. 97.5°C/W for standard SOIC), allowing 2.18 W power dissipation at TA ≤25°C |
| High output current | ±250 mA drive supports direct connection to 40-Ω loads - eliminates need for external buffer transistors in Pin driver designs |
| Low harmonic distortion | −66 dBc HD2 / −76 dBc HD3 at 10 MHz enables >10-bit SFDR in arbitrary waveform generators without post-filtering |
| Wide common-mode input range | ±13.6 V at ±15 V supply - accepts large AC-coupled signals without clipping or bias network complexity |
| 0.1-dB bandwidth flatness | 50 MHz at G = 2 - ensures amplitude consistency across video baseband (DC–6 MHz) and IF bands (up to 50 MHz) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, high-output-current amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091DR | Single-channel version; identical specs except per-channel quiescent current (9.5 mA) and no crosstalk specification | Lacks dual-channel integration; requires two devices for stereo or differential output paths | Select THS3091DR only when board space permits discrete channel layout and crosstalk isolation is not required |
| THS3491IRHFT | Higher slew rate (9500 V/µs), lower distortion (−72 dBc HD2 @ 10 MHz), but narrower supply range (±12 V max) and no PowerPAD™ | Superior dynamic performance but limited to ±12 V systems; lacks thermal robustness for sustained high-power operation | Choose THS3491IRHFT for ultra-low-distortion applications below ±12 V; retain THS3092DDAG4 for ±15 V industrial or telecom systems requiring thermal margin |
Compared with THS3091DR and THS3491IRHFT, THS3092DDAG4 uniquely combines dual-channel integration, ±15 V operation, PowerPAD™ thermal management, and proven 160-MHz bandwidth - making it the optimal choice for space-constrained, high-reliability line driver and waveform generator designs where supply headroom and thermal safety are critical.

FAQ
What is the maximum safe operating junction temperature for THS3092DDAG4?
The THS3092DDAG4 has a maximum junction temperature of 150°C for absolute ratings, but continuous operation above 125°C degrades long-term reliability and increases distortion. With its PowerPAD™ package and θJA of 45.8°C/W, proper PCB thermal design (≥1-in² copper pour) keeps TJ ≤125°C at 2.18 W dissipation - ensuring stable performance in industrial environments.
Does THS3092DDAG4 support single-supply operation?
Yes, THS3092DDAG4 operates from a single supply of 10 V to 30 V. When used in single-supply mode, the input common-mode range extends to within 1.4 V of VS− and VS+, and output swing reaches within 1.5 V of each rail. Figure 54 in the datasheet shows a DC-coupled configuration using split-rail biasing for video applications.
How does THS3092DDAG4 differ from THS3096 in pin compatibility?
THS3092DDAG4 (SOIC-8 PowerPAD™) and THS3096 (SOIC-8 or TSSOP-14) share identical pinouts for the 8-pin SOIC variants - Pins 1–8 map identically. However, THS3096 adds PD and REF pins in its 14-pin TSSOP package, which are NC on THS3092DDAG4. No PCB redesign is needed when substituting the SOIC-8 versions.
What is the recommended feedback resistor for G = 5 operation with THS3092DDAG4?
For G = 5 with RL = 100 Ω, TI specifies RF = 715 Ω and RG = 178 Ω to minimize peaking and maximize bandwidth flatness. This combination yields 160 MHz small-signal bandwidth and 50 MHz 0.1-dB flatness - critical for preserving signal integrity in wideband applications like IF amplification and arbitrary waveform generation.
Can THS3092DDAG4 drive capacitive loads directly?
THS3092DDAG4 can drive up to 100 pF capacitive loads stably when using the recommended series isolation resistor (RISO). For example, with RF = 715 Ω and G = 5, RISO = 15 Ω is advised for CL = 100 pF (Figure 8). Larger capacitive loads require increased RISO or external compensation to prevent oscillation and maintain 42 ns settling time.
