Product details
Overview
THS4001IDG4 from Texas Instruments is a voltage-feedback high-speed operational amplifier optimized for professional video signal conditioning and precision analog front-ends. It delivers 270 MHz bandwidth (G = 1, –3 dB), 400 V/µs slew rate, and 40 ns settling time to 0.1%, operating from ±2.5 V to ±15 V supplies with 7.5 mA quiescent current. Its 0.04% differential gain and 0.15° differential phase errors enable broadcast-grade video reconstruction in RGB or Y/C paths.
For engineers reviewing the THS4001IDG4 datasheet, THS4001IDG4 pinout, THS4001IDG4 application, or THS4001IDG4 equivalent, key selection criteria include unity-gain stability across supply voltages, 100 mA output drive into 150 Ω loads, low 12.5 nV/√Hz input noise, and SOIC-8 packaging compatible with standard PCB layouts for high-frequency analog routing.
Technical Context
The THS4001IDG4 employs a dielectrically isolated complementary bipolar process enabling simultaneous high fT, low distortion, and wide supply range operation. Its internal compensation ensures unconditional stability at all gains in both inverting and noninverting configurations without external components.
It features dual null pins (1 and 8) for offset trimming, supports capacitive load isolation via series output resistors (≥20 Ω), and maintains 60 MHz 0.1 dB bandwidth at G = +1 - critical for composite video baseband preservation and ADC driver applications requiring minimal group delay variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 270 MHz at G = +1, ±15 V - enables full HD video signal amplification without attenuation up to Nyquist frequency. |
| Slew Rate | 400 V/µs - supports clean 10 V step response with <40 ns settling to 0.1%, essential for fast pulse and transient fidelity. |
| Differential Gain/Phase | 0.04% / 0.15° at 3.58 MHz - meets SMPTE 170M broadcast video accuracy requirements for color fidelity. |
| Total Harmonic Distortion | –72 dBc at 1 MHz - ensures minimal spectral contamination in RF sampling chains and IF signal paths. |
| Supply Voltage Range | ±2.5 V to ±15 V (dual) or 5 V to 32 V (single) - allows direct integration into legacy ±15 V systems and modern low-voltage embedded platforms. |
| Output Drive | 100 mA into 20 Ω - drives coaxial cables, back-terminated video lines, and multiplexed ADC inputs without gain degradation. |
| Input Noise Voltage | 12.5 nV/√Hz at 10 kHz - preserves SNR in low-level sensor signal amplification stages prior to digitization. |
Pinout & Package
THS4001IDG4 is housed in an 8-pin SOIC (D) package per JEDEC MS-012AA, with 1.27 mm pitch, 3.91 mm body width, and 1.75 mm max height. Pin 1 identifier is located at the top-left corner of the package marking area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null Input | Connects to wiper of external potentiometer for fine-tuning input offset voltage; unused pins must remain unconnected. |
| 2 (IN–) | Inverting Input | High-impedance node for feedback network connection; trace length must be minimized to reduce parasitic capacitance and ringing. |
| 3 (IN+) | Noninverting Input | High-impedance reference input; requires matched layout symmetry with IN– to preserve CMRR above 1 MHz. |
| 4 (VCC–) | Negative Supply Rail | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum capacitor placed ≤2.5 mm from pin to suppress high-frequency supply noise. |
| 5 (NULL) | Offset Null Return | Connected to negative supply rail when using external nulling circuit; left open if offset adjustment is not required. |
| 6 (OUT) | Amplifier Output | Capable of sourcing/sinking 100 mA; requires series resistor ≥20 Ω when driving >10 pF capacitive loads to maintain phase margin. |
| 7 (VCC+) | Positive Supply Rail | Decoupling identical to VCC–; shared bulk capacitors allowed only if adjacent amplifiers operate at same frequency band. |
| 8 (NC) | No Internal Connection | Not bonded internally; must remain unconnected on PCB to avoid unintended coupling or EMI pickup. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-Gain Stable | Operates stably at G = +1 and G = –1 without external compensation, simplifying design of video line drivers and active filters. |
| Wide Supply Range | Supports ±2.5 V to ±15 V dual supplies or 5 V to 32 V single supply - eliminates need for level-shifting in mixed-voltage systems. |
| Low Distortion | –72 dBc THD at 1 MHz enables use in high-fidelity signal chains where harmonic artifacts degrade downstream FFT analysis or demodulation. |
| Video-Optimized Performance | 0.1 dB flatness to 60 MHz and 0.04%/0.15° differential gain/phase meet ITU-R BT.601 and SMPTE 259M standards for SD/HD video. |
| High Output Current | Delivers 100 mA into 20 Ω loads - sufficient to drive multiple 75 Ω video lines simultaneously or terminate transmission lines directly. |

FAQ
What is the operating temperature range for the THS4001IDG4?
The THS4001IDG4 is rated for industrial operation from –40°C to +85°C, matching the "I" suffix designation in its part number. This range is validated per TI's recommended operating conditions and supported by thermal derating data in the dissipation rating table for the SOIC-8 package.
Does the THS4001IDG4 require external compensation for unity-gain stability?
No, the THS4001IDG4 is internally compensated and unconditionally stable at unity gain (G = +1) and inverting unity gain (G = –1) configurations. No external capacitors or resistors are needed for basic operation, though a 200 Ω feedback resistor is recommended to minimize peaking in noninverting unity-gain setups.
Can the THS4001IDG4 drive a 75-Ω video cable directly?
Yes - the THS4001IDG4 can drive 75-Ω coaxial video lines directly when configured with a 75 Ω series output resistor. This isolates capacitive loading, maintains impedance matching at the source end, and prevents high-frequency ringing caused by unterminated transmission lines.
What is the purpose of pins 1 and 5 on the THS4001IDG4?
Pins 1 (NULL) and 5 (NULL) form the offset nulling interface. A potentiometer is connected between them, with its wiper tied to VCC–, allowing manual adjustment of input offset voltage. These pins are unused in standard configurations and must remain unconnected unless fine offset correction is required.
How does the THS4001IDG4 compare to the THS4001CD in terms of performance and qualification?
The THS4001IDG4 and THS4001CD share identical electrical specifications and silicon die; the difference lies solely in temperature grading and packaging. The "I" suffix denotes –40°C to +85°C operation, while "C" is 0°C to +70°C. Both use the same SOIC-8 (D) package and deliver identical 270 MHz bandwidth, 400 V/µs slew rate, and video performance metrics.
