Product details
Overview
THS4001CDR from Texas Instruments is a voltage-feedback high-speed operational amplifier optimized for professional video signal conditioning and wideband analog signal 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. Its 0.04% differential gain and 0.15° differential phase enable broadcast-grade video line driving.
For engineers reviewing the THS4001CDR datasheet, THS4001CDR pinout, THS4001CDR application, or THS4001CDR equivalent, key selection criteria include unity-gain stability across inverting/noninverting configurations, 100 mA output drive into 150 Ω, low 12.5 nV/√Hz input noise, and SOIC-8 packaging compatible with standard PCB assembly processes.
Technical Context
The THS4001CDR employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, resulting in voltage-feedback architecture with intrinsic unity-gain stability and minimal phase margin trade-offs. Its internal compensation targets optimal bandwidth/slew rate balance without external components.
It supports dual-supply operation from ±2.5 V to ±15 V and single-supply operation from 5 V to 32 V, maintaining specified AC performance across temperature (0°C to 70°C) and load conditions (150 Ω, 500 Ω). Input common-mode range extends to ±13.5 V at ±15 V supply, and output swing reaches ±10 V into 500 Ω.
Key Specifications

Pinout & Package
THS4001CDR is housed in an 8-pin SOIC (D) package with 1.27 mm pitch, 3.9 mm width, and 1.75 mm max height per JEDEC MS-012 AA. The package supports tape-and-reel delivery (2500 units/reel) and is RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

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 |
|---|---|---|---|
| THS4031CDR | 100 MHz bandwidth, 100 V/µs slew rate, lower 1.6 nV/√Hz noise | Better suited for precision low-distortion audio or medium-bandwidth instrumentation where speed is secondary to noise | Select THS4031CDR when bandwidth ≤100 MHz suffices and input noise must be minimized below 2 nV/√Hz |
| THS4061CDR | 180 MHz bandwidth, 400 V/µs slew rate, 14.5 nV/√Hz noise, improved 0.02% differential gain | Targeted at higher-accuracy video applications requiring tighter gain flatness but slightly reduced bandwidth | Choose THS4061CDR for enhanced video fidelity at 180 MHz, accepting minor bandwidth reduction versus THS4001CDR |
Compared with THS4031CDR and THS4061CDR, the THS4001CDR provides the highest bandwidth (270 MHz) and fastest settling (40 ns) in the family, making it optimal for ultra-wideband signal paths where speed dominates over ultimate noise or differential gain specs.

FAQ
What is the maximum operating temperature range for the THS4001CDR?
The THS4001CDR is rated for operation from 0°C to 70°C ambient temperature, as indicated by its "C" suffix and confirmed in the Recommended Operating Conditions table. This commercial-grade temperature range aligns with its SOIC-D packaging and tape-and-reel configuration (THS4001CDR), distinguishing it from the industrial-grade THS4001ID variant.
Does the THS4001CDR require external compensation for unity-gain stability?
No, the THS4001CDR is internally compensated for unity-gain stability in both inverting and noninverting configurations. Its design maintains adequate phase margin at G = 1 without external components, though a 200 Ω feedback resistor is recommended for optimal settling time and minimal ringing in noninverting unity-gain applications.
Can the THS4001CDR drive a 75-Ω transmission line directly?
Yes, the THS4001CDR can drive a 75-Ω load directly, delivering ±10 V output swing into 500 Ω and sustaining 100 mA output current. For 75-Ω coaxial lines, a series 75 Ω resistor at the output is recommended to isolate capacitive loading and provide proper source termination, per Figure 22 in the datasheet.
What is the purpose of Pins 1 and 5 on the THS4001CDR?
Pin 1 (NULL) is an offset null input terminal used with an external potentiometer to adjust input offset voltage; Pin 5 (NULL) has no internal connection and must remain unconnected. Both pins are electrically isolated from the die - misconnecting Pin 5 risks introducing noise or instability.
How does the THS4001CDR's power supply rejection ratio (PSRR) perform across frequency?
The THS4001CDR maintains ≥75 dB PSRR up to 10 kHz and >60 dB up to 10 MHz at ±15 V supply, as shown in Figure 9. This high PSRR ensures robust immunity to supply rail noise in mixed-signal systems, preserving signal integrity when sharing power domains with digital ICs or switching regulators.
