Texas Instruments THS3096D

Overview

THS3096D 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, and features an integrated power-down pin (PD) reducing quiescent current from 9.5 mA to 500 µA. It operates across ±5 V to ±15 V supplies and drives capacitive and resistive loads in VDSL line driver and Pin driver applications.

For engineers reviewing the THS3096D datasheet, THS3096D pinout, THS3096D application, or THS3096D equivalent, this page provides verified electrical specifications, SOIC-8 package layout, power-down timing behavior, thermal derating guidance, and validated alternatives for high-voltage, low-distortion signal chain design.

Technical Context

The THS3096D uses 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 fast settling (42 ns to 0.1%) and high slew rate (5700 V/µs at G = 5, VO = 20 VPP).

Power-down functionality is implemented via a dedicated PD pin referenced to an internal REF node (VS− to VS+ − 4 V), requiring ≥REF + 2 V to enable and ≤REF + 0.8 V to disable. Turnon/turnoff delays are 60 µs and 150 µs respectively, with guaranteed 500 µA max quiescent current in standby mode.

Key Specifications

Pinout & Package

THS3096D is housed in an 8-pin SOIC (D) package with exposed pad thermally isolated from pins. The package supports standard reflow profiles and requires PCB copper pour under the PowerPAD™ for thermal management per TI SLMA002.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage, low-distortion operational amplifier applications.

Compared with THS3092D, THS3096D adds power-down control at the cost of two unused pins (PD/REF) in SOIC-8; compared with THS4271DR, it trades bandwidth and DC accuracy for higher output current and dual-channel integration-making THS3096D optimal for space-constrained, high-power analog output stages.

FAQ

What is the maximum safe operating junction temperature for THS3096D?

The THS3096D has a maximum continuous junction temperature of 125°C for long-term reliability; operation above this threshold increases distortion and risks permanent damage. Thermal design must ensure θJA ≤97.5°C/W (SOIC-8) with adequate PCB copper pour under the PowerPAD™ to maintain TJ ≤125°C at full load and 85°C ambient.

How does the power-down feature of THS3096D behave when the REF pin is unconnected?

When the REF pin is left unconnected, the THS3096D defaults to enabled (ON) state per datasheet Note A. The internal REF node floats near VS−, so PD ≥ REF + 2 V is satisfied by typical logic-high signals. For robust operation, TI recommends tying REF to a stable voltage between VS− and VS+ − 4 V, such as mid-supply via resistor divider.

Can THS3096D drive a 50 Ω load at ±15 V supply with 20 VPP output?

No-THS3096D delivers ±12.5 V swing into 100 Ω and ±11.8 V into 40 Ω at ±15 V supply. Driving 50 Ω at ±15 V would require >±12.5 V swing, exceeding its specified output voltage range. For 50 Ω loads, use G = 5, VO = 10 VPP or lower, or add external current-boosting circuitry.

What is the recommended feedback resistor value for THS3096D at G = 5 with 100 Ω load?

Texas Instruments specifies RF = 715 Ω and RG = 178 Ω for G = 5, RL = 100 Ω to minimize peaking and maximize bandwidth (160 MHz). Using values outside Table 1 (e.g., RF = 1 kΩ) reduces bandwidth and may induce instability; RF < 715 Ω increases bandwidth but adds gain peaking above 100 MHz.

Does THS3096D support single-supply operation, and what is the minimum supply voltage?

Yes-THS3096D supports single-supply operation from 10 V to 30 V (e.g., +12 V and GND). At 10 V supply, common-mode input range is ±3 V and output swing is ±2.5 V into 100 Ω. Full performance (e.g., ±12.5 V swing) requires ±15 V dual supply or ≥30 V single supply.
