Product details
Overview
THS4001CD from Texas Instruments is a voltage-feedback high-speed operational amplifier optimized for professional video signal conditioning and precision wideband analog processing. 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. It is widely deployed in broadcast-grade video line drivers and high-fidelity ADC/DAC interface circuits.
For engineers reviewing the THS4001CD datasheet, THS4001CD pinout, THS4001CD application, or THS4001CD equivalent, key selection criteria include its stable unity-gain operation, differential gain/phase performance (0.04%/0.15°), low 12.5 nV/√Hz input noise, and SOIC-8 package compatibility with standard PCB layout practices for >100 MHz signal integrity.
Technical Context
The THS4001CD employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, resulting in voltage-feedback architecture with inherently wide bandwidth and minimal phase shift up to 100 MHz. Its internal compensation ensures stability across all closed-loop gains, including noninverting G = +1 configurations without external compensation.
It features dual null pins (1 and 8) for offset trimming, rail-to-rail input common-mode range (±13.5 V at ±15 V supply), and robust output drive (±100 mA into 20 Ω). The device maintains 60 MHz 0.1 dB gain flatness and –72 dBc THD at 1 MHz, making it suitable for composite video, RGB component routing, and high-resolution imaging front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 270 MHz at G = +1, ±15 V - enables full HD video baseband amplification without attenuation |
| Slew Rate | 400 V/µs - supports fast transient response for pulse and digital waveform conditioning |
| Settling Time (0.1%) | 40 ns at ±15 V - meets timing budgets for 10-bit+ sampling systems with <10 ns aperture uncertainty |
| Differential Gain / Phase | 0.04% / 0.15° at 3.58 MHz - satisfies SMPTE/EBU broadcast video fidelity requirements |
| Input Noise Voltage | 12.5 nV/√Hz at 10 kHz - preserves SNR in low-level analog signal chains before ADC |
| Supply Range | ±2.5 V to ±15 V (dual) or 5 V to 32 V (single) - supports legacy ±15 V lab equipment and modern low-voltage embedded systems |
| Output Drive | ±100 mA into 20 Ω - drives coaxial cables, back-terminated video lines, and heavy capacitive loads with series isolation |
Pinout & Package
THS4001CD is housed in an 8-pin SOIC (D) package per JEDEC MS-012AA, 1.75 mm max height, with gull-wing leads and NIPDAU lead finish. Pin 1 identifier is marked in the top-left corner of the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset Null Input | Connects to wiper of external potentiometer for fine input offset voltage adjustment |
| 2 (IN–) | Inverting Input | High-impedance node for feedback network connection; requires shortest possible trace length |
| 3 (IN+) | Noninverting Input | High-impedance node for signal source; sensitive to stray capacitance and EMI coupling |

| 5 (NULL) | Offset Null Return | Connected to negative supply rail to complete offset trim circuit |
| 6 (OUT) | Amplifier Output | Capable of sourcing/sinking ±100 mA; requires series resistor for >10 pF capacitive loads |
| 7 (VCC+) | Positive Supply Rail | Must be decoupled identically to VCC–; shared decoupling not recommended for multi-amplifier layouts |
| 8 (NC) | No Internal Connection | Unbonded die pad; electrically isolated and must remain unconnected on PCB |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4031CD | Lower bandwidth (100 MHz), lower slew rate (100 V/µs), superior THD (–72 dBc same), smaller input bias current (2.6 µA vs 5 µA) | Better suited for lower-frequency precision video or audio where power efficiency and distortion matter more than speed | Select THS4031CD when bandwidth <120 MHz suffices and quiescent current reduction is prioritized |
| THS4061CD | Higher bandwidth (180 MHz), same slew rate (400 V/µs), higher input noise (14.5 nV/√Hz), improved differential phase (0.02°) | Optimized for demanding RGB or YPbPr component video where phase linearity outweighs absolute bandwidth | Choose THS4061CD for multi-channel sync-critical video systems requiring tighter phase matching across channels |
Compared with THS4001CD, THS4031CD trades bandwidth for lower power and THS4061CD improves phase fidelity at moderate bandwidth-neither is pin-compatible, but all three share SOIC-8 packaging and similar layout requirements for high-frequency stability.

FAQ
What is the maximum operating temperature range for the THS4001CD?
The THS4001CD is rated for operation from 0°C to 70°C (commercial temperature grade). Its absolute maximum junction temperature is 150°C, and thermal derating begins above 25°C ambient at 6 mW/°C. For extended temperature applications, the THS4001ID variant supports –40°C to +85°C and is functionally identical except for qualification testing.
Does the THS4001CD require external compensation for unity-gain stability?
No, the THS4001CD is internally compensated for unity-gain stability in both inverting and noninverting configurations. Its design maintains phase margin ≥45° at G = +1, eliminating the need for external compensation. However, for optimal step response with minimal ringing, TI recommends using a 200 Ω feedback resistor in noninverting unity-gain setups as shown in the THS4001CD application schematic.
Can the THS4001CD drive a 75-Ω coaxial video line directly?
Yes, the THS4001CD can drive a 75-Ω load directly when configured with proper source termination: place a 75 Ω series resistor between the THS4001CD output (pin 6) and the coaxial cable. This isolates capacitive loading, prevents high-frequency oscillation, and matches the characteristic impedance-enabling stable, low-reflection transmission of composite or component video signals.
What is the purpose of pins 1 and 5 on the THS4001CD?
Pins 1 (NULL) and 5 (NULL) on the THS4001CD are dedicated offset null terminals. They form a two-point interface for connecting an external 10 kΩ potentiometer: the wiper connects to VCC– (pin 4), and the two ends connect to pins 1 and 5. Adjusting the potentiometer trims input offset voltage to <1 mV, essential for DC-coupled precision applications like medical imaging or calibrated test equipment using THS4001CD.
Is the THS4001CD RoHS compliant and what is its moisture sensitivity level?
Yes, the THS4001CD is RoHS compliant (lead-free, NIPDAU finish) and rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH). It is qualified for peak reflow temperatures up to 260°C and shipped in tube packaging (75 units) or tape-and-reel (2500 units for THS4001CDR). The device meets TI's standard reliability and environmental compliance requirements for commercial-grade analog ICs.
