Product details
Overview
THS3001IDR from Texas Instruments is a high-speed current-feedback operational amplifier designed for precision wideband signal conditioning in demanding analog front-ends. It delivers 420MHz small-signal bandwidth (G = 1, –3dB), 6500V/μs slew rate at ±15V supply, and 40ns settling time to 0.1%, enabling accurate amplification of fast video, imaging, and communication waveforms in base station DAC buffers and high-definition video line drivers.
For engineers reviewing the THS3001IDR datasheet, THS3001IDR pinout, THS3001IDR application, or THS3001IDR equivalent, key selection criteria include its current-feedback architecture's gain-bandwidth independence, low 3mV max input offset voltage, –96dBc THD at 1MHz, ±4.5V to ±16V dual-supply operation, and SOIC-8 package compatibility with high-density PCB layouts.
Technical Context
The THS3001IDR employs a dielectrically isolated complementary bipolar (HVBiCOM) process with GHz fT transistors, enabling true current-feedback topology where bandwidth is set primarily by feedback resistor value-not closed-loop gain. Its transresistance-based architecture decouples gain-setting from bandwidth control, allowing stable high-frequency operation without phase-margin degradation typical of voltage-feedback amplifiers.
Functional operation requires dual ±4.5V to ±16V supplies or single 9V–32V rails, with internal biasing optimized for low distortion across temperature. Input stage features separate noninverting (IN+) and inverting (IN–) terminals with 15Ω inverting input resistance and 1.5MΩ noninverting input resistance, while output drives up to 100mA into 150Ω loads with ±12.8V swing at ±15V supply.
Key Specifications

| Small-signal BW | 420MHz at G = 1, –3dB (±15V): enables full HD/3G-SDI video amplification without roll-off |
| Slew rate | 6500V/μs (±15V, G = –5): supports clean 10V step transitions in <40ns for ADC/DAC buffering |
| THD | –96dBc at 1MHz, 2VPP: ensures minimal harmonic contamination in wireless IF stages |
| Input offset | 3mV max (25°C): reduces DC error in precision gain blocks without external trimming |
| Supply range | ±4.5V to ±16V dual or 9V–32V single: accommodates legacy ±5V and modern ±12V/±15V systems |
| Output drive | 100mA into 150Ω (±5V): directly drives coaxial cables or back-terminated video lines |
| Settling time | 40ns to 0.1% (G = –1, ±15V, 0V→10V step): meets timing budgets in high-speed data acquisition |
Pinout & Package
THS3001IDR is packaged in an 8-pin SOIC (D package), 4.9mm × 6mm body size, with exposed pad not present and standard JEDEC MS-012AC footprint. Pin 1 is NC (no internal connection); pins 2 and 3 are IN– and IN+, respectively; pins 4 and 7 are VCC– and VCC+ power terminals; pin 6 is the high-current OUT; pins 1, 5, and 8 are NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8 NC | No internal connection | Unused pins; must remain unconnected or grounded per layout best practices to minimize parasitics |
| 2 IN– | Inverting input | Low-impedance node (15Ω) accepting feedback network; sensitive to PCB trace capacitance |
| 3 IN+ | Noninverting input | High-impedance node (1.5MΩ); used for reference or signal injection in noninverting configurations |
| 4 VCC– | Negative supply rail | Return path for internal bias currents; requires local 0.1μF + 10μF bypassing near pin |
| 6 OUT | Amplifier output | Capable of ±12.8V swing into 1kΩ and 100mA into 150Ω; direct drive for 75Ω video loads |
| 7 VCC+ | Positive supply rail | Primary power input; supplies output stage current; bypassing critical for stability at >100MHz |

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 |
|---|---|---|---|
| THS3091DR | Higher 900MHz bandwidth but lower 3000V/μs slew rate; 10mA quiescent current vs 7.5mA | Better for RF sampling front-ends requiring >500MHz flatness; less suitable for large-signal video drive | Select THS3091DR when bandwidth >600MHz is mandatory and slew rate >5000V/μs is acceptable |
| LMH6723MA/NOPB | Lower 280MHz bandwidth, higher 12mV VIO, 100mA output drive retained; SOIC-8 compatible | Cost-optimized alternative for industrial video where 115MHz 0.1dB flatness suffices | Choose LMH6723MA/NOPB for cost-sensitive HD-SDI receivers where THS3001IDR's 420MHz is over-spec |
Compared with THS3001IDR, THS3091DR trades slew rate for bandwidth-making it superior in RF sampling but inferior in video pulse fidelity-while LMH6723MA/NOPB offers lower cost and adequate performance for standard-definition video, sacrificing precision DC specs and high-frequency linearity.

FAQ
What is the maximum operating supply voltage for THS3001IDR?
The THS3001IDR supports dual-supply operation from ±4.5V to ±16V (32V total) or single-supply from 9V to 32V. Absolute maximum ratings specify ±16.5V per rail; exceeding this risks permanent damage. At ±15V, the device achieves its full 420MHz bandwidth and 6500V/μs slew rate, making ±15V the recommended nominal condition for high-performance applications.
Does THS3001IDR support single-supply operation?
Yes, THS3001IDR operates with single supplies from 9V to 32V. Its input common-mode range extends to within 3.2V of either rail at ±5V and ±13.2V at ±15V, enabling rail-to-rail input capability when biased appropriately. For single-supply video applications, a mid-rail reference (e.g., VCC/2) must be applied to IN+ to establish proper DC operating point.
What feedback resistor value is recommended for THS3001IDR at G = 2?
For THS3001IDR configured at G = 2 with ±15V supplies, TI recommends RF = 680Ω (Table 7-1). This value balances bandwidth (385MHz), phase margin, and distortion (–80dBc THD at 10MHz). Using 1% tolerance metal-film resistors is critical-higher tolerances degrade frequency response consistency and increase harmonic distortion due to loop-gain variation.
How does THS3001IDR's current-feedback architecture affect gain stability?
Unlike voltage-feedback op-amps, THS3001IDR's bandwidth is set by feedback resistor value-not closed-loop gain-so increasing gain via RG does not reduce bandwidth. This allows stable 420MHz operation at G = 1 while maintaining >350MHz at G = 5. Stability depends on precise RF selection; deviating from recommended values (e.g., 1kΩ for G = 1) causes peaking or roll-off.
Is THS3001IDR suitable for driving 75Ω video loads?
Yes, THS3001IDR delivers 100mA output current and ±12.8V swing into 1kΩ at ±15V, enabling direct 75Ω video drive with proper termination. Its 115MHz 0.1dB flatness, 0.01% differential gain, and 0.02° differential phase meet SMPTE 259M/424M broadcast standards. Layout requires short traces, ground plane beneath, and 75Ω series termination at source to prevent reflections.
