Texas Instruments THS3096PWPR

Overview

THS3096PWPR from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier with power-down capability, 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, and 5700 V/µs slew rate under ±15 V supply - enabling clean, high-fidelity signal amplification in RF test equipment and VDSL line drivers.

For engineers reviewing the THS3096PWPR datasheet, THS3096PWPR pinout, THS3096PWPR application, or THS3096PWPR equivalent, this page provides verified electrical specifications, TSSOP-14 PowerPAD™ package details, power-down timing behavior, thermal derating guidance, and real-world design context for high-voltage, low-distortion analog signal paths.

Technical Context

The THS3096PWPR 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 transimpedance gain exceeds 850 kΩ at ±15 V, supporting stable operation with RF values as low as 178 Ω for G = 5.

It features an active-low power-down pin (PD) referenced to an internal REF voltage rail (VS− to VS+ − 4 V), with 60 µs turn-on delay and 150 µs turn-off delay. Quiescent current drops from 9.5 mA/channel to 500 µA during power-down, while maintaining defined input bias and output impedance behavior.

FAQ

What is the maximum safe junction temperature for continuous operation of the THS3096PWPR?

The THS3096PWPR has a maximum junction temperature of 125°C for continuous operation to ensure long-term reliability and stable distortion performance. Exceeding this limit increases harmonic distortion and risks permanent degradation. Thermal design must use ΘJC = 2.07°C/W and ΘJA = 37.5°C/W (JEDEC High-K PCB) with PowerPAD™ soldered to a thermal plane.

How does the power-down feature of the THS3096PWPR affect output behavior during assertion?

When the PD pin is asserted low (≤ REF + 0.8 V), the THS3096PWPR disables its output stage and reduces quiescent current to 500 µA per channel. The outputs enter high-impedance state with <1 µA leakage, preventing loading of downstream circuits. Turnoff delay is 150 µs to 10% of final value; output remains functional until fully disabled.

Can the THS3096PWPR operate from a single 24-V supply, and what are the implications?

Yes - the THS3096PWPR supports single-supply operation from 10 V to 30 V. At 24 V, the usable output swing is ±11.8 V into 100 Ω (per Electrical Characteristics table), and quiescent current rises to ~10.5 mA/channel. Input common-mode range becomes 0 V to 19 V, requiring careful DC biasing of VIN+ pins to avoid clipping.

What is the recommended minimum RF value for stable G = 5 operation with the THS3096PWPR?

Texas Instruments specifies 715 Ω as the optimal RF for G = 5 with RL = 100 Ω to minimize peaking and maximize bandwidth (160 MHz). Using RF < 715 Ω increases bandwidth but introduces gain peaking; RF > 715 Ω improves stability at the cost of bandwidth reduction. Do not use RF < 178 Ω without thorough stability analysis.

Does the THS3096PWPR require external compensation components for unity-gain stability?

No - the THS3096PWPR is unity-gain stable per datasheet (SLOS428B, p.16). It achieves 135 MHz bandwidth at G = 1 with RF = 1.1 kΩ and exhibits no oscillation or ringing in standard test configurations. However, capacitive loads >100 pF require series RISO (e.g., 15 Ω for CL = 100 pF) to maintain phase margin.
