Product details
Overview
THS3201MDGNREP from Texas Instruments is a radiation-hardened, high-speed current-feedback amplifier optimized for defense, aerospace, and medical applications requiring ultra-low distortion and wide bandwidth. It delivers 1.8-GHz unity-gain bandwidth, 6700 V/µs slew rate (G = 2, ±7.5 V), –78 dBc IMD3 at 20 MHz, 11-dB noise figure (G = 10), and ±7.5-V dual-supply operation - enabling high-fidelity arbitrary waveform generation and high-resolution ADC driving.
For engineers reviewing the THS3201MDGNREP datasheet, THS3201MDGNREP pinout, THS3201MDGNREP application, or THS3201MDGNREP equivalent, key selection criteria include its 8-pin MSOP-PowerPAD™ package, extended temperature range (–55°C to +125°C), low input-referred voltage noise (1.65 nV/√Hz), and compatibility with ±3.3 V to ±7.5 V supplies in precision analog signal chains.
Technical Context
The THS3201MDGNREP implements a current-feedback architecture with 16-Ω inverting input impedance and 780-kΩ noninverting input resistance, enabling stable gain-setting via external feedback resistors (e.g., RF = 768 Ω for G = 2). Its transimpedance gain exceeds 100 kΩ over temperature, supporting fast settling (20 ns to 0.1%) and near-step-independent rise/fall times (0.7/0.9 ns).
Designed for extended-life military and space-grade systems, it features controlled baseline, single-fab/supply/test-site traceability, and thermal pad (PowerPAD™) requiring PCB connection to ground or thermal plane. Absolute maximum supply voltage is 16.5 V, with continuous output drive capability of ±100 mA into 100 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 1.8 GHz at ±7.5 V - enables direct drive of >1-GHz sampling ADCs without intermediate buffering. |
| Slew Rate | 6700 V/µs (G = 2, 5-V step, RL = 100 Ω) - supports clean large-signal transient response in pulse amplification. |
| IMD3 Distortion | –78 dBc at 20 MHz (G = 10, 2-VPP envelope, RL = 100 Ω) - meets stringent spectral purity requirements in comms and radar IF stages. |
| Noise Figure | 11 dB (G = 10, RG = 28 Ω, RF = 255 Ω) - minimizes system noise floor degradation in low-level signal conditioning paths. |
| Supply Voltage Range | ±3.3 V to ±7.5 V - accommodates both low-power portable systems and high-voltage test equipment rails. |
| Input Voltage Noise | 1.65 nV/√Hz (f > 10 MHz) - preserves SNR in wideband receiver front-ends and instrumentation amplifiers. |
| Operating Temperature | –55°C to +125°C - qualified for harsh-environment deployment in avionics, satellite payloads, and battlefield electronics. |
Pinout & Package
THS3201MDGNREP uses an 8-pin MSOP package with exposed thermal pad (PowerPAD™), requiring solder connection to a thermally conductive PCB plane per TI SLMA002/SLMA004 guidelines. The thermal pad is electrically isolated from internal circuitry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Must be left unconnected; no routing or grounding required. |
| 2 (VIN−) | Inverting input | Low-impedance node (16 Ω) accepting feedback network; sets closed-loop gain with RF. |
| 3 (VIN+) | Noninverting input | High-impedance node (780 kΩ); used for reference biasing or signal injection in noninverting configurations. |
| 4 (VS−) | Negative supply rail | Connect to system negative supply; decoupling capacitor (e.g., 0.1 µF) required adjacent to pin. |
| 5 (NC) | No internal connection | Must be left unconnected; no routing or grounding required. |
| 6 (VS+) | Positive supply rail | Connect to system positive supply; decoupling capacitor (e.g., 0.1 µF) required adjacent to pin. |
| 7 (VOUT) | Amplifier output | Capable of ±100 mA drive into 100 Ω; requires series isolation resistor for capacitive loads > 10 pF. |
| 8 (NC) | No internal connection | Must be left unconnected; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Radiation-hardened EP grade | Qualified for space and defense use with controlled baseline, extended product life cycle, and full traceability. |
| Current-feedback topology | Enables bandwidth scalability independent of closed-loop gain - 850 MHz small-signal BW at G = +2, 565 MHz at G = +5. |
| PowerPAD™ thermal enhancement | θJA = 58.4°C/W (JEDEC High-K board); thermal pad must be soldered to copper pour for reliable 125°C operation. |
| Low distortion at high frequency | –73 dBc third-harmonic distortion at 10 MHz (G = +5) ensures fidelity in video, IF, and arbitrary waveform synthesis. |
| Wide common-mode input range | ±5.1 V (min) at ±7.5 V supply - simplifies level-shifting in bipolar signal chains interfacing with FPGAs or DACs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202MDGNREP | Dual-channel version with identical specs per channel; higher quiescent current (2×18 mA max) and larger die area. | Required when simultaneous dual-path amplification is needed (e.g., I/Q modulation, differential signaling). | Select THS3202MDGNREP only if dual-channel functionality is essential; THS3201MDGNREP offers lower power and smaller footprint for single-ended designs. |
| THS3001MDWREP | Higher supply range (±15 V), lower bandwidth (420 MHz), higher slew rate (3200 V/µs), and higher distortion (–64 dBc IMD3 @ 10 MHz). | Better suited for high-voltage, lower-frequency applications like piezoelectric actuator drivers or legacy test gear. | Choose THS3001MDWREP when ±15-V rails and >10-VPP output are mandatory; THS3201MDGNREP excels where bandwidth and distortion dominate. |

FAQ
What is the maximum operating junction temperature for THS3201MDGNREP?
The THS3201MDGNREP has a maximum junction temperature of 150°C for absolute maximum ratings, but its recommended continuous operating junction temperature is limited to 125°C for long-term reliability. Thermal design must ensure θJA = 58.4°C/W (MSOP-PowerPAD™) is maintained using adequate PCB copper area connected to the thermal pad, especially under ±7.5-V, high-output-current conditions.
Does THS3201MDGNREP support single-supply operation?
Yes, THS3201MDGNREP supports single-supply operation from 6.6 V to 15 V, as specified in the Recommended Operating Conditions table. However, its input common-mode range and output swing are optimized for symmetric dual supplies (±3.3 V to ±7.5 V); single-supply use requires careful DC biasing of VIN+ and load termination to preserve linearity and avoid clipping.
How does the PowerPAD™ thermal pad on THS3201MDGNREP affect PCB layout?
The PowerPAD™ thermal pad on THS3201MDGNREP must be soldered to a dedicated, low-thermal-resistance PCB copper plane - typically connected to ground or the most negative supply - to achieve rated θJA = 58.4°C/W. Failure to connect the pad results in excessive junction temperature rise and potential device failure. TI technical briefs SLMA002 and SLMA004 provide verified layout guidelines for thermal pad implementation.
What is the typical input bias current of THS3201MDGNREP at 25°C?
At 25°C and ±7.5-V supply, THS3201MDGNREP exhibits typical input bias current of ±13 µA at the inverting input and ±14 µA at the noninverting input. These values increase with temperature, reaching up to ±90 µA (inverting) and ±60 µA (noninverting) at 125°C - a critical consideration for high-impedance feedback networks or precision DC-coupled stages.
Can THS3201MDGNREP drive a 50-Ω load directly?
Yes, THS3201MDGNREP can drive a 50-Ω load directly, delivering ±5.7 V output swing (min) and ±100 mA output current (min) at ±7.5-V supply. For optimal stability and distortion performance, a series isolation resistor (e.g., 10–22 Ω) is recommended between VOUT and the 50-Ω load to dampen potential peaking caused by trace inductance or connector capacitance.
