Product details
Overview
THS3091IDGNR from Texas Instruments is a high-voltage, current-feedback operational amplifier optimized for high-fidelity, high-slew-rate output drive in demanding linear applications. It delivers 6000 V/μs slew rate (G = 5), 305 MHz small-signal bandwidth (G = 2, RL = 100 Ω), ±310 mA output current, 1.1 nV/√Hz voltage noise, and –84 dBc HD2 at 10 MHz into 1 kΩ - enabling precision pin driver and arbitrary waveform generator output stages.
For engineers reviewing the THS3091IDGNR datasheet, THS3091IDGNR pinout, THS3091IDGNR application, or THS3091IDGNR equivalent, key selection criteria include high-voltage swing capability (±12.5 V into 100 Ω), low distortion under large-signal conditions, thermal performance in HVSSOP-8, and compatibility with fast settling (12.5 ns to 0.1%) in closed-loop configurations.
Technical Context
The THS3091IDGNR uses a current-feedback architecture with high-impedance noninverting input and low-impedance inverting input, enabling stable gain-bandwidth tradeoffs independent of closed-loop gain. Its transimpedance gain stage drives a Class-AB output stage capable of sourcing/sinking ±310 mA while maintaining linearity up to 20 VPP.
Designed for ±5 V to ±16 V dual-supply operation, it features rail-to-rail output swing capability (±12.5 V into 100 Ω at TA = 85°C), 15 pA/√Hz noninverting current noise, and robust ESD protection (±2000 V HBM). No power-down pin is present - distinguishing it from the THS3095 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±16 V - supports high-voltage signal generation without external boost circuitry |
| Slew Rate | 6000 V/μs (G = 5, VO = 20 VPP) - enables fast edge fidelity in pulse and waveform shaping |
| Small-Signal Bandwidth | 305 MHz (G = 2, RL = 100 Ω) - maintains gain flatness for RF and wideband analog signal paths |
| Output Current Drive | ±310 mA - directly drives low-impedance loads (e.g., 40 Ω FET gates or piezo elements) |
| Harmonic Distortion | –84 dBc HD2 / –99 dBc HD3 at 10 MHz, RL = 1 kΩ - preserves spectral purity in precision waveform synthesis |
| Voltage Noise Density | 1.1 nV/√Hz - minimizes added noise in high-gain, low-level signal conditioning stages |
| Input Current Noise | 15 pA/√Hz (noninverting), 14 pA/√Hz (inverting) - critical for high-Z sensor interface stability |
Pinout & Package
HVSSOP-8 (DGN) package with exposed thermal pad (PowerPAD™); 2.0 mm × 3.0 mm footprint, 0.5 mm pitch, 1.0 mm height - optimized for thermal dissipation in space-constrained high-power analog layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NC | No internal connection | Unused pin; must be left floating or tied to ground per layout best practices |
| 2 VIN− | Inverting input | Low-impedance node (30 Ω) accepting feedback network; sets closed-loop gain and stability |
| 3 VIN+ | Noninverting input | High-impedance node (700 kΩ) for reference or signal injection; minimal bias current (4–15 μA) |
| 4 VS− | Negative supply rail | Connects to system negative rail; supports up to ±16 V operation and handles 9.5 mA quiescent current |
| 5 NC | No internal connection | Unused pin; no internal bond wire; avoid routing signals nearby |
| 6 VOUT | Amplifier output | Capable of ±310 mA drive into 40 Ω; requires series isolation resistor (RISO) when driving >10 pF capacitive loads |
| 7 VS+ | Positive supply rail | Connects to system positive rail; shares same voltage range and current capability as VS− |
| 8 NC | No internal connection | Unused pin; thermally connected to PowerPAD; recommended to solder to ground plane |
Key Features

| Low-distortion large-signal response | –84 dBc HD2 at 10 MHz into 1 kΩ ensures clean spectral content for arbitrary waveform generator outputs |
| Thermally enhanced HVSSOP-8 (DGN) | RθJB = 32.6 °C/W enables sustained 1.5 W dissipation in compact PCB layouts without forced air cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-speed amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3095IDDA | Includes power-down pin (PD); SOIC-8 (DDA) package only; identical AC/DC specs except PD-related quiescent current (500 μA vs. 9.5 mA) | Required where system-level power gating is needed; not suitable for space-constrained layouts due to larger SOIC footprint | Select THS3095IDDA only if power-down functionality is mandatory and board area permits SOIC-8 |
| THS3491IRHFT | Higher slew rate (8000 V/μs), wider bandwidth (900 MHz at G = 5), but higher supply current (17.3 mA) and voltage noise (1.7 nV/√Hz) | Better suited for >50 MHz RF signal generation; less optimal for low-noise, medium-frequency precision waveform synthesis | Choose THS3491IRHFT when bandwidth >500 MHz is required and 0.6 nV/√Hz noise penalty is acceptable |
Compared with THS3095IDDA, THS3091IDGNR offers superior thermal performance in HVSSOP and eliminates power-down complexity; versus THS3491IRHFT, it trades 295 MHz bandwidth for 0.6 nV/√Hz lower noise and 8.8 mA lower quiescent current - favoring precision over raw speed.

FAQ
What is the maximum supply voltage rating for THS3091IDGNR?
The THS3091IDGNR has an absolute maximum supply voltage of ±16 V (32 V total), with recommended operating range from ±5 V to ±16 V. Operation beyond ±16 V risks permanent damage per Absolute Maximum Ratings table. At ±15 V, it delivers full 6000 V/μs slew rate and 305 MHz bandwidth - making THS3091IDGNR ideal for high-dynamic-range signal generation without external rails.
Does THS3091IDGNR include a power-down feature?
No, THS3091IDGNR does not include a power-down pin. That function is exclusive to the THS3095 variant (e.g., THS3095IDDA). The THS3091IDGNR operates continuously with typical quiescent current of 9.5 mA at ±15 V - optimized for always-on, high-fidelity output stages where latency and wake-up timing are not design constraints.
What is the recommended isolation resistor (RISO) when driving capacitive loads with THS3091IDGNR?
For stable operation driving >10 pF capacitive loads, THS3091IDGNR requires an external series isolation resistor (RISO) between VOUT and the load. Per Figure 7-8, RISO = 22.1 Ω is recommended for 47 pF, and RISO = 15.8 Ω for 100 pF - values derived from stability analysis across gain and load conditions. Omitting RISO risks peaking or oscillation in high-frequency closed-loop configurations.
Can THS3091IDGNR drive a 100 Ω load to ±12 V with low distortion?
Yes - THS3091IDGNR delivers ±12.1 V output swing into 100 Ω at TA = 25°C (±11.8 V at +85°C) with measured –72 dBc HD2 and –70 dBc HD3 at 10 MHz. This performance meets stringent distortion requirements for ATE pin drivers and waveform generators, confirmed in Electrical Characteristics Table 7.5 under RL = 100 Ω conditions.
What thermal metrics apply to the HVSSOP-8 (DGN) package of THS3091IDGNR?
The THS3091IDGNR in HVSSOP-8 (DGN) package has RθJA = 60.4 °C/W (JEDEC JESD51-2), RθJB = 32.6 °C/W, and RθJC(bot) = 17.0 °C/W. With 9.5 mA quiescent current at ±15 V (0.285 W), junction temperature rise above ambient is ~17°C - well within 125°C continuous operation limit. Thermal pad soldering to PCB ground plane is mandatory to achieve rated RθJB.
