Product details
Overview
THS3095D from Texas Instruments is a high-voltage, current-feedback operational amplifier optimized for large-signal, high-speed applications. It delivers ±310 mA output drive, 6000 V/μs slew rate (G = 5), 205 MHz small-signal bandwidth (G = 5), and features a dedicated power-down pin (PD) enabling quiescent current reduction from 9.5 mA to 500 μA - used in pin drivers and high-voltage arbitrary waveform generators.
For engineers reviewing the THS3095D datasheet, THS3095D pinout, THS3095D application, or THS3095D equivalent, this page provides verified technical context, package-validated pin functions, real-world distortion/noise performance at 10 MHz, power-down timing (60 μs turn-on), and design-meaningful alternatives for high-output-current, low-distortion amplifier selection.
Technical Context
The THS3095D uses a current-feedback architecture with transimpedance gain stage, enabling wide bandwidth independent of closed-loop gain. Its input stage supports ±13.6 V common-mode range (±15 V supply), and output drives ±12.5 V into 100 Ω while maintaining <0.01% settling in 18.5 ns.
Power-down functionality is implemented via a voltage-comparator-based control circuit referenced to the REF pin, requiring PD ≥ REF + 2 V to enable and PD ≤ REF + 0.8 V to disable - with 150 μs turn-off delay and 500 μA standby current at 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±5 V to ±16 V - supports dual-rail industrial and test equipment rails without level-shifting. |
| Slew Rate | 6000 V/μs (G = 5, VO = 20 VPP) - enables clean 20-VPP step response at >10 MHz without slewing-induced distortion. |
| Small-Signal BW | 205 MHz (G = 5, RL = 100 Ω) - maintains flat gain up to 95 MHz (0.1-dB flatness), critical for wideband pulse fidelity. |
| Output Current | ±310 mA - drives low-Z loads (e.g., 40 Ω FET gates or piezo stacks) without clipping or thermal foldback. |
| Harmonic Distortion | –84 dBc HD2 / –99 dBc HD3 at 10 MHz, RL = 1 kΩ - ensures spectral purity in arbitrary waveform synthesis. |
| Voltage Noise | 1.1 nV/√Hz - preserves SNR in high-gain, wideband signal chains where voltage noise dominates. |
| Power-Down Current | 500 μA (TA = 25°C) - reduces system idle power by >94% versus active mode (9.5 mA), enabling burst-mode operation. |
Pinout & Package
THS3095D is packaged in an 8-pin SOIC PowerPAD™ (DDA) with exposed thermal pad for enhanced heat dissipation. The package supports surface-mount reflow and requires PCB thermal vias under the pad per TI's layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | REF | Reference input for power-down threshold; sets enable/disable voltage window relative to VS−. |
| 2 | VIN− | Inverting input node; low impedance (30 Ω) suited for current-feedback topology stability. |
| 3 | VIN+ | Noninverting input node; high impedance (0.7 MΩ) with 2.4 pF capacitance for AC-coupled signal routing. |
| 4 | VS− | Negative supply rail connection; must be decoupled locally with ≥100 nF ceramic capacitor. |
| 5 | NC | No internal connection - left unconnected; not usable as thermal pad tie or ground. |
| 6 | VOUT | Amplifier output; capable of ±12.5 V swing into 100 Ω with <0.01% settling in 18.5 ns. |
| 7 | VS+ | Positive supply rail connection; symmetric ±16 V max rating enables bipolar high-voltage operation. |
| 8 | PD | Active-high power-down control; logic-compatible input with 11–15 μA bias current and 60 μs turn-on delay. |
Key Features
| Feature | Design Value |
|---|---|
| Power-down pin (PD) | Reduces quiescent current from 9.5 mA to 500 μA, enabling energy-efficient burst-mode driver operation. |
| High output current drive | ±310 mA sourcing/sinking capability allows direct driving of power-FET gates and piezoelectric actuators. |
| Low harmonic distortion | –99 dBc HD3 at 10 MHz ensures minimal spectral regrowth in arbitrary waveform generator outputs. |
| Wide supply range | ±5 V to ±16 V operation eliminates need for external DC-DC converters in mixed-voltage test systems. |
| Current-feedback architecture | Delivers stable 205 MHz bandwidth at G = 5 - unlike voltage-feedback op-amps, bandwidth remains gain-independent. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output-current, current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3091D | No power-down pin; identical bandwidth, slew rate, and output drive but higher quiescent current (9.5 mA always on). | Lacks burst-mode power gating - unsuitable for battery-powered or thermally constrained SMU modules. | Select THS3091D only when continuous operation is required and PCB space permits omitting PD control logic. |
| THS3491D | Higher slew rate (8000 V/μs), wider bandwidth (900 MHz at G = 1), but lower max supply (±6 V) and reduced output current (±420 mA). | Better for RF/IF signal paths up to 500 MHz, but cannot replace THS3095D in ±15 V high-voltage driver roles. | Choose THS3491D for wideband, low-voltage, high-fidelity signal chain stages - not for high-voltage pin or piezo driving. |
Compared with THS3091D and THS3491D, the THS3095D uniquely combines ±16 V operation, integrated power-down, and ±310 mA drive - making it the only option among the three for energy-aware, high-voltage arbitrary waveform generation and ATE pin driving.

FAQ
What is the maximum supply voltage for the THS3095D?
The THS3095D supports a maximum dual-supply voltage of ±16 V (32 V total), with absolute maximum ratings specifying 33 V across VS+ and VS−. Operation beyond ±16 V risks exceeding junction temperature limits and violating recommended operating conditions - always verify thermal design using RθJA = 58.4°C/W for the DDA package when operating near max supply.
How does the power-down feature of the THS3095D work?
The THS3095D power-down feature is activated by pulling the PD pin to a voltage ≥ REF + 2 V, disabling the amplifier and reducing quiescent current to 500 μA. The REF pin sets the reference threshold, and turn-on delay is 60 μs to 90% of final output. This function is exclusive to THS3095D - not present in THS3091D - and requires no external components beyond standard supply decoupling.
What load conditions achieve the 205 MHz bandwidth specification for the THS3095D?
The 205 MHz small-signal bandwidth (–3 dB) for THS3095D is measured at G = 5, RL = 100 Ω, and RF = 1 kΩ with ±15 V supplies. Bandwidth drops to 160 MHz at ±5 V supply and varies with feedback resistor value - e.g., 305 MHz at G = 2, RF = 1.21 kΩ. Load capacitance degrades bandwidth unless compensated with series isolation resistor (RISO), per Figure 7-8.
Can the THS3095D drive a 100-pF capacitive load stably?
Yes, the THS3095D can drive 100-pF loads stably when paired with a 15.8-Ω series isolation resistor (RISO) at the output, as specified in Figure 7-8 of the datasheet. Without RISO, capacitive loading causes peaking and potential oscillation due to phase margin degradation - this compensation method preserves 0.1-dB flatness up to 95 MHz and maintains 18.5 ns 0.01% settling time.
What is the harmonic distortion performance of the THS3095D at 1 MHz and 20-VPP output?
At 1 MHz and 20-VPP output (G = 5, RL = 1 kΩ), the THS3095D achieves –80 dBc HD2 and –75 dBc HD3, per Figure 7-11. This is 4–5 dB worse than its 10-MHz, 4-VPP spec (–84 dBc HD2 / –99 dBc HD3) due to increased slew-induced distortion at higher amplitudes - confirming its suitability for high-fidelity, medium-amplitude wideband signals rather than ultra-low-distortion RF applications.
