Product details
Overview
THS3201DGNG4 from Texas Instruments is a 1.8-GHz current-feedback amplifier (CFA) optimized for high-speed, low-distortion signal conditioning in ±7.5 V systems. It delivers 6700 V/µs slew rate (G = 2, 10-V step), –78 dBc IMD3 at 20 MHz, 1.65 nV/√Hz input voltage noise, and 100 mA output drive into 100 Ω - enabling precision arbitrary waveform generation and high-resolution ADC/DAC buffering.
For engineers reviewing the THS3201DGNG4 datasheet, THS3201DGNG4 pinout, THS3201DGNG4 application, or THS3201DGNG4 equivalent, key selection criteria include its wideband current-feedback architecture, PowerPAD™-enhanced MSOP-8 thermal performance, ±3.3 V to ±7.5 V supply flexibility, and verified distortion performance at 100+ MHz frequencies in test & measurement and ATE signal chains.
Technical Context
The THS3201DGNG4 employs a current-feedback topology with ultra-low inverting input impedance (~11 Ω) and high noninverting input impedance (~780 kΩ), enabling stable gain-setting via RF/RG networks independent of closed-loop bandwidth. Its transimpedance gain exceeds 120 kΩ over temperature, supporting precise current-to-voltage conversion in high-speed feedback paths.
Designed for ±7.5 V operation (with absolute max ±8.25 V), it achieves 880 MHz large-signal bandwidth (2 VPP) and 0.7 ns rise time while maintaining <0.01° differential phase error in video applications - critical for multi-load analog signal distribution and high-fidelity pulse amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 1.8 GHz - enables stable operation up to 100+ MHz with minimal phase margin degradation in CFA configurations. |
| Slew Rate | 6700 V/µs (G = 2, 10-V step) - supports fast edge fidelity in arbitrary waveform drivers and pulse amplifiers. |
| IMD3 | –78 dBc at 20 MHz (G = 10, 2-VPP envelope) - ensures clean spectral purity for high-dynamic-range signal generation. |
| Input Voltage Noise | 1.65 nV/√Hz (f > 10 MHz) - minimizes added noise in wideband front-end amplification stages. |
| Output Drive | 100 mA into 100 Ω - sustains full-scale swing across reactive and resistive loads in high-speed buffer applications. |
| Supply Range | ±3.3 V to ±7.5 V - accommodates legacy ±5 V and modern ±7.5 V test equipment rails without redesign. |
| Operating Temp | –40°C to +85°C - qualified for industrial and ATE environments with guaranteed performance across full range. |
Pinout & Package
The THS3201DGNG4 is housed in an 8-pin MSOP package with PowerPAD™ thermal enhancement (DGN suffix). The exposed thermal pad must be soldered to a PCB copper plane for reliable power dissipation; failure to do so risks junction temperature exceedance above +125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–) | Inverting Input | Low-impedance node (~11 Ω) for feedback network connection; sets closed-loop gain with RF. |
| 2 (VS–) | Negative Supply | Connects to –7.5 V rail; decoupling capacitor required near pin for high-frequency stability. |
| 3 (VOUT) | Output | Capable of sourcing/sinking 100 mA; requires careful layout to minimize parasitic inductance. |
| 4 (VS+) | Positive Supply | Connects to +7.5 V rail; decoupling capacitor required near pin for PSRR optimization. |
| 5 (IN+) | Noninverting Input | High-impedance node (~780 kΩ); used for unity-gain follower or noninverting configurations. |
| 6–8 (NC) | No Internal Connection | Unused pins; must remain unconnected per TI datasheet Note A. |
Key Features
| Feature | Design Value |
|---|---|
| Current-Feedback Architecture | Enables bandwidth scaling with gain - unlike voltage-feedback op-amps - preserving speed at G = 10 without compensation. |
| PowerPAD™ Thermal Package | DGN package's exposed die pad reduces θJA to 58.4°C/W, allowing 1.71 W power dissipation at TA ≤ +25°C. |
| Ultra-Low Distortion | –78 dBc IMD3 at 20 MHz ensures minimal intermodulation artifacts in multi-tone test signals for ATE validation. |
| Wide Supply Flexibility | Operates from ±3.3 V to ±7.5 V - simplifies integration into mixed-supply systems without level-shifting circuitry. |
| High Output Current | 100 mA drive capability maintains signal integrity into 100 Ω loads and capacitive cables common in oscilloscope probe drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202DGNR | Dual-channel version with identical AC specs (1.8 GHz BW, –78 dBc IMD3), but higher quiescent current (2× per channel). | Requires dual-output signal paths; not suitable for single-amplifier space-constrained layouts. | Select when two matched CFAs are needed on one board; shares same DGN package footprint and thermal design. |
| OPA695IDBVR | 1.7-GHz CFA with lower supply range (±5 V only), higher input bias current (±25 µA vs ±14 µA), and no PowerPAD™ package option. | Limited to ±5 V systems; less thermally robust in continuous high-power operation. | Choose for cost-sensitive ±5 V designs where thermal headroom is sufficient and dual-supply flexibility is unnecessary. |
Compared with THS3202DGNR and OPA695IDBVR, the THS3201DGNG4 uniquely combines ±7.5 V operation, PowerPAD™ thermal efficiency, and single-channel optimization - making it the preferred choice for high-power, high-precision single-amplifier roles in ATE and instrumentation where supply headroom and thermal reliability are critical.

FAQ
What is the maximum recommended supply voltage for THS3201DGNG4?
The THS3201DGNG4 has an absolute maximum supply voltage rating of ±8.25 V, but the recommended operating range is ±3.3 V to ±7.5 V. Operating at ±7.5 V delivers optimal bandwidth (1.8 GHz) and slew rate (6700 V/µs); exceeding ±7.5 V risks accelerated parametric drift and reduced long-term reliability, even if within absolute maximum limits.
Does THS3201DGNG4 require external compensation components?
No, the THS3201DGNG4 is internally compensated for unity-gain stability in current-feedback configuration. Gain is set solely by external RF and RG resistors; no additional capacitors or feedback networks are needed for stable operation across its specified bandwidth, simplifying layout and reducing bill-of-materials count.
How does the PowerPAD™ on THS3201DGNG4 affect thermal design?
The PowerPAD™ on the THS3201DGNG4 is an electrically isolated thermal pad on the underside of the MSOP-8 package. It must be soldered to a dedicated PCB copper pour connected to ground or thermal plane to achieve the rated θJA of 58.4°C/W. Without this connection, junction temperature can exceed +125°C under 100 mA load, triggering thermal shutdown or permanent damage.
Can THS3201DGNG4 drive a 50 Ω coaxial cable directly?
Yes, the THS3201DGNG4 can drive a 50 Ω coaxial cable directly when configured as a gain-of-2 inverting amplifier with appropriate RF/RG values (e.g., RF = 576 Ω, RG = 576 Ω). Its 100 mA output current and 0.01 Ω closed-loop output impedance ensure minimal signal loss and reflection - provided proper source termination and PCB layout minimize parasitic inductance.
Is THS3201DGNG4 suitable for driving SAR ADC inputs?
Yes, the THS3201DGNG4 is well-suited for driving successive-approximation register (SAR) ADC inputs due to its fast settling time (20 ns to 0.1%), low distortion (–78 dBc IMD3), and ability to handle the switched-capacitor input transient. When paired with a 100 Ω series resistor and proper decoupling, it maintains SNR and SFDR performance in 16-bit, 10-MSPS+ SAR ADC applications.
