Texas Instruments THS3096PWP

Overview

THS3096PWP from Texas Instruments is a dual-channel, high-voltage, current-feedback operational amplifier optimized for low-distortion, high-slew-rate signal amplification in ±5 V to ±15 V supplies. It delivers 5700 V/µs slew rate (G = 5, VO = 20 VPP), −66 dBc 2nd harmonic distortion at 10 MHz (RL = 100 Ω), and ±250 mA output drive - enabling use in high-voltage arbitrary waveform generator output stages and power FET drivers.

For engineers reviewing the THS3096PWP datasheet, THS3096PWP pinout, THS3096PWP application, or THS3096PWP equivalent, key selection criteria include its TSSOP-14 PowerPAD™ package with dedicated power-down (PD) and reference (REF) pins, 160 MHz small-signal bandwidth at G = 5, and verified performance driving capacitive and resistive loads up to 100 Ω while maintaining <72 ns 0.01% settling time.

Technical Context

The THS3096PWP employs a current-feedback architecture 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 stable operation with RF values as low as 178 Ω for G = 5.

Power-down functionality is implemented via a dedicated PD pin referenced to an internal REF node (range: VS− to VS+ − 4 V); asserting PD ≥ REF + 2 V disables both channels, reducing quiescent current from 9.5 mA to 500 µA. Turnon/turnoff delays are 60 µs and 150 µs respectively, with no external pull-up required as the device defaults to ON when PD is unconnected.

FAQ

What is the maximum output voltage swing of the THS3096PWP at ±15 V supply?

The THS3096PWP delivers ±12.5 V output voltage swing into a 100 Ω load and ±13.2 V into a 1 kΩ load at ±15 V supply, as specified in the Electrical Characteristics table under "Output voltage swing" at TA = 25°C. This high swing capability enables direct interfacing with legacy test equipment and high-voltage analog subsystems without additional level-shifting circuitry.

Does the THS3096PWP require external compensation for stability?

No, the THS3096PWP is unity-gain stable and does not require external compensation components. Its current-feedback architecture achieves stable operation across gains of 1 to 10 using only the recommended RF/RG resistor values from Table 1 in the datasheet - for example, RF = 715 Ω and RG = 178 Ω for G = 5 with RL = 100 Ω.

How is the power-down function implemented on the THS3096PWP?

The THS3096PWP uses a dedicated PD pin referenced to an internal REF node (VS− to VS+ − 4 V). Applying a voltage ≥ REF + 2 V to PD disables both amplifiers, reducing quiescent current to 500 µA. The device powers up automatically when PD is left open or pulled ≤ REF + 0.8 V, with 60 µs turnon delay and 150 µs turnoff delay.

Can the THS3096PWP drive capacitive loads without oscillation?

Yes, the THS3096PWP can drive capacitive loads up to 100 pF stably when used with the recommended RISO isolation resistor (e.g., 15 Ω for CL = 100 pF, G = 5, RL = 100 Ω), as shown in Figure 8 of the datasheet. Without RISO, instability may occur above ~22 pF; layout best practices include short traces and local decoupling near VS+/VS− pins.

What is the thermal requirement for reliable operation of the THS3096PWP in TSSOP-14 package?

Reliable operation of the THS3096PWP requires connecting the PowerPAD™ underside thermal pad to a PCB copper plane with ≥4 thermal vias (0.3 mm diameter) to an internal ground or thermal layer. This achieves ΘJA = 37.5°C/W, limiting junction temperature to ≤125°C at 2.67 W dissipation - exceeding the 1.07 W limit of the SOIC-8 variant under same conditions.
