Texas Instruments THS3096DRG4

Overview

THS3096DRG4 from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier with power-down capability, designed for high-fidelity arbitrary waveform generation and 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, and 5700 V/µs slew rate under ±15 V supply - enabling precise high-swing signal amplification in VDSL and Pin driver applications.

For engineers reviewing the THS3096DRG4 datasheet, THS3096DRG4 pinout, THS3096DRG4 application, or THS3096DRG4 equivalent, this page provides verified electrical specifications, SOIC-8 and TSSOP-14 package mapping, power-down timing behavior, real-world distortion vs. frequency curves, and validated alternatives for high-voltage, low-distortion analog signal path design.

Technical Context

The THS3096DRG4 employs 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 circuit uses a REF pin referenced to VS− and requires PD ≥ REF + 2 V to enable, with 60 µs turn-on delay and 150 µs turn-off delay.

It operates across ±5 V to ±15 V dual supplies (or 10–30 V single supply), supports rail-to-rail output swing up to ±12.5 V into 100 Ω, and maintains <0.02° differential phase error in video applications. The device features matched input bias currents (≤20 µA max) and low noise: 2 nV/√Hz voltage noise and 13 pA/√Hz current noise.

Key Specifications

Pinout & Package

THS3096DRG4 is available in SOIC-8 (D) and TSSOP-14 (PWP) packages with PowerPAD™ thermal enhancement. The SOIC-8 variant uses pins 1–8 as shown in the top-view diagram; the TSSOP-14 adds dedicated REF and PD control pins (pins 11 and 13) and two NC terminals.

FAQ

What is the maximum supply voltage rating for THS3096DRG4?

The THS3096DRG4 supports dual-supply operation from ±5 V to ±15 V (33 V total), with absolute maximum supply voltage rated at ±16 V. Exceeding ±16 V risks permanent damage. For single-supply use, it accepts 10 V to 30 V between VS+ and VS−, with proper input common-mode and output swing constraints applied per the datasheet's recommended operating conditions.

Does THS3096DRG4 support true rail-to-rail output swing?

No, THS3096DRG4 does not provide rail-to-rail output. At ±15 V supply and RL = 100 Ω, its guaranteed minimum output voltage swing is ±12.5 V - meaning it saturates approximately 2.5 V below VS+ and above VS−. This headroom is necessary to maintain linearity and low distortion; attempting to drive beyond this range increases harmonic content and may cause instability.

How does the power-down feature of THS3096DRG4 behave during power sequencing?

The THS3096DRG4 defaults to enabled (active) if no signal is applied to the PD pin. During power-up, the REF pin must stabilize before asserting PD; applying PD ≥ REF + 2 V after REF is valid initiates shutdown within 150 µs. If PD is asserted before REF reaches its valid range, behavior is undefined - TI recommends coordinating PD assertion with established VS+ and VS− rails and REF settling.

Can THS3096DRG4 drive a 50 Ω coaxial cable directly without external matching?

Yes, THS3096DRG4 can drive 50 Ω loads directly: its specified output current (±250 mA) and output voltage swing (±12.5 V into 100 Ω, implying ~±6.25 V into 50 Ω) support 50 Ω termination. However, for optimal high-frequency flatness and return loss, TI recommends adding a series 5.11 Ω resistor (RISO) between output and cable to dampen resonance caused by cable capacitance - as validated in Figure 7 and Figure 31 of the datasheet.

What is the thermal impact of omitting PowerPAD™ connection on THS3096DRG4 in TSSOP-14 package?

Omitting the PowerPAD™ thermal connection on THS3096DRG4 (PWP package) severely degrades thermal performance: ΘJA rises from 37.5°C/W to >100°C/W, causing junction temperature to exceed 125°C at just ~300 mW dissipation. This triggers distortion increase and risks long-term reliability failure. TI mandates soldering the PowerPAD™ to a minimum 1-in² copper pour with ≥4 thermal vias to ground for rated 1.07 W operation at TA = 85°C.
