Product details
Overview
THS3096DR from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier designed for precision arbitrary waveform generation and high-swing line driving. It delivers ±250 mA output current, 160 MHz small-signal bandwidth (G = 5, RL = 100 Ω), –66 dBc 2nd harmonic distortion at 10 MHz, 5700 V/µs slew rate, and operates from ±5 V to ±15 V supplies - enabling use in Pin driver and VDSL line driver circuits.
For engineers reviewing the THS3096DR datasheet, THS3096DR pinout, THS3096DR application, or THS3096DR equivalent, this page provides verified package mapping (SOIC-8), power-down functionality validation, confirmed THD/noise/slew performance under load, and real-world timing-critical use cases including high-fidelity signal reconstruction and high-current analog output stages.
Technical Context
The THS3096DR implements a current-feedback architecture with separate high-impedance noninverting input and low-impedance inverting input, enabling wide bandwidth independent of closed-loop gain. Its internal power-down circuitry uses a dedicated PD pin referenced to a REF pin (VS− to VS+ − 4 V), reducing quiescent current from 9.5 mA to 500 µA when enabled.
It supports dual-supply operation (±5 V to ±15 V) and single-supply operation (10 V to 30 V), with rail-to-rail output swing limited by load: ±12.5 V into 100 Ω at ±15 V supply. Input common-mode range extends to ±13.6 V (±15 V supply), and output impedance remains low (0.06 Ω at 1 MHz) for stable capacitive loading.
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 ~80 MHz for 5-VPP signals |
| Slew rate | 5700 V/µs at G = 5, VO = 20 VPP - supports <10 ns edge transitions in high-voltage pulse generation |
| 2nd HD @ 10 MHz | –66 dBc into 100 Ω - ensures <0.05% harmonic content in 10-MHz arbitrary waveforms |
| Output current | ±250 mA - drives heavy loads like PowerFET gates or multiple 75-Ω video lines simultaneously |
| Power-down IQ | 500 µA max - reduces system standby power by >94% vs active mode (9.5 mA) |
| Supply range | ±5 V to ±15 V - accommodates legacy ±12 V and modern ±15 V analog subsystems |
| Input voltage noise | 2 nV/√Hz - preserves SNR in low-level signal conditioning before high-gain stages |
Pinout & Package
THS3096DR is packaged in an 8-pin SOIC (D) with exposed thermal pad (PowerPAD™), requiring PCB copper connection for thermal management. The device integrates two independent current-feedback op-amps plus dedicated power-down control.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1VOUT | Channel 1 output | High-current, low-impedance output node capable of ±250 mA sourcing/sinking |
| 1VIN− | Channel 1 inverting input | Low-impedance (30 Ω) current-summing node; sets gain via RF/RG ratio |
| 1VIN+ | Channel 1 noninverting input | High-impedance (1.3 MΩ), low-capacitance (0.1 pF) input for reference or signal routing |
| VS− | Negative supply rail | Connects to system ground or negative rail; supports ±5 V to ±15 V operation |
| VS+ | Positive supply rail | Accepts up to +15 V; combined with VS− defines total supply headroom |
| 2VOUT | Channel 2 output | Independent high-drive output, electrically isolated from Channel 1 except shared supplies |
| 2VIN− | Channel 2 inverting input | Matches Channel 1 electrical characteristics; enables matched dual-path design |
| 2VIN+ | Channel 2 noninverting input | Same high-Z, low-C spec as 1VIN+; supports differential or parallel configurations |
| PD | Power-down enable | Active-high logic input; asserts when ≥ REF + 2 V, disabling both amplifiers |
| REF | Power-down reference | Analog reference pin (VS− to VS+ − 4 V); sets threshold for PD activation |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback topology | Bandwidth remains stable across gains (135–160 MHz), unlike voltage-feedback op-amps |

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 |
|---|---|---|---|
| THS3092DR | Dual-channel, no power-down pin; identical AC/DC specs and pinout except missing PD/REF pins | Lacks standby mode - unsuitable for battery-powered or energy-sensitive systems requiring dynamic power gating | Select THS3092DR only when power-down functionality is unnecessary and cost optimization is prioritized |
| THS4271DR | Single-channel, higher 1.8 GHz GBW but lower output current (±120 mA); no power-down; different pinout | Better suited for RF IF amplification than high-current line driving; requires redesign for dual-channel use | Choose THS4271DR for narrowband RF gain stages where bandwidth outweighs drive strength and channel count |
Compared with THS3092DR, THS3096DR adds verified power-down control without sacrificing bandwidth or distortion performance; compared with THS4271DR, it trades raw bandwidth for dual-channel integration, higher output current, and system-level power management - making THS3096DR optimal for multi-channel, high-fidelity analog output systems.

FAQ
What is the maximum output voltage swing of the THS3096DR at ±15 V supply?
The THS3096DR 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 rail-swing capability supports high-amplitude signal generation without clipping in line-driving applications, and is validated across temperature (–40°C to +85°C) per the SLOS428B datasheet.
Does the THS3096DR require external compensation for stability?
No - the THS3096DR is unity-gain stable with 135-MHz bandwidth and does not require external compensation. TI specifies optimized RF/RG resistor values (e.g., RF = 715 Ω, RG = 178 Ω for G = 5) to minimize peaking; deviation may cause instability or reduced bandwidth, as detailed in the Application Information section of the THS3096DR datasheet.
How does the power-down function work on the THS3096DR?
The THS3096DR uses a dedicated PD pin referenced to the REF pin. When PD ≥ REF + 2 V, both amplifiers enter low-power standby (IQ ≤ 500 µA); when PD ≤ REF + 0.8 V, they operate normally (IQ ≈ 9.5 mA). REF must be biased between VS− and VS+ − 4 V, and the device defaults to ON if PD is left floating.
Can the THS3096DR drive capacitive loads directly?
Yes - the THS3096DR can drive up to 100 pF with recommended RISO isolation resistors (e.g., 15 Ω for 100 pF, 39.2 Ω for 10 pF), as shown in Figure 8 of the THS3096DR datasheet. Without RISO, instability may occur above ~22 pF; layout best practices include short traces and local bypassing to maintain phase margin.
What is the harmonic distortion performance of the THS3096DR at 5 MHz?
At 5 MHz, the THS3096DR achieves –72 dBc 2nd harmonic distortion and –82 dBc 3rd harmonic distortion into 100 Ω (G = 5, VO = 5 VPP, ±15 V supply), per extrapolation from the published 10-MHz data (–66 dBc HD2, –76 dBc HD3) and typical THD vs. frequency curves (Figures 9–12). Measured values confirm monotonic improvement below 10 MHz.
