Product details
Overview
THS4052CD from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier designed for precision video, imaging, and communication signal conditioning. It delivers 70 MHz bandwidth (G = 1), 240 V/µs slew rate, 60 ns settling time (0.1%), ±15 V supply operation, and 0.01% differential gain error - enabling broadcast-quality analog video distribution in SD/HD systems.
For engineers reviewing the THS4052CD datasheet, THS4052CD pinout, THS4052CD application, or THS4052CD equivalent, this device is selected for high-fidelity analog signal paths requiring wide small-signal bandwidth, low distortion at 1 MHz (−82 dBc), stable unity-gain operation, and dual-channel synchronization without crosstalk degradation (−57 dB @ 1 MHz).
Technical Context
The THS4052CD employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture optimized for speed and linearity. Its internal compensation ensures stability across all gains in both inverting and non-inverting configurations without external compensation.
It features matched dual channels with independent input/output stages, null pins for offset trimming, and rail-to-rail output swing capability (±13.6 V into 1 kΩ at ±15 V supplies). Channel-to-channel crosstalk is specified at −57 dB at 1 MHz, confirming isolation suitable for multi-channel video routing and simultaneous sampling applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - supports full NTSC/PAL baseband video bandwidth with margin |
| Slew rate | 240 V/µs at ±15 V - enables clean 20-V step response within 100 ns, critical for fast transient fidelity |
| Settling time (0.1%) | 60 ns at ±15 V - ensures accurate pixel-level settling in high-resolution analog video DAC buffers |
| Differential gain/phase | 0.01% / 0.01° at NTSC, ±15 V - meets SMPTE RP-168 broadcast video accuracy requirements |
| Total harmonic distortion | −82 dBc at 1 MHz, 2 VPP, 150 Ω - preserves signal integrity in RF IF stages and ADC driver applications |
| Supply range | ±4.5 V to ±16.5 V dual supply - accommodates legacy ±5 V, ±12 V, and industrial ±15 V systems |
| Output drive | 100 mA typical per channel - drives 75 Ω coaxial lines, multiple op-amp inputs, or ADC reference buffers directly |
Pinout & Package
THS4052CD is packaged in an 8-pin SOIC (D package) with exposed pad thermal enhancement. The package measures 3.91 mm × 4.9 mm × 1.75 mm (body) and supports standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current, low-distortion output node; requires local 0.1 µF bypass to VCC− |
| 1IN− | Channel 1 inverting input | Differential input node; matched impedance critical for common-mode rejection |
| 1IN+ | Channel 1 non-inverting input | Differential input node; connects to source or feedback network |
| −VCC | Negative supply rail | Power return path; must be low-inductance, decoupled near pin |
| VCC+ | Positive supply rail | Power input; requires 0.1 µF ceramic + 4.7 µF tantalum decoupling |
| 2OUT | Channel 2 output | Independent high-drive output; electrically isolated from 1OUT to minimize crosstalk |
| 2IN− | Channel 2 inverting input | Second differential pair input; pin-to-pin matched with 1IN− for timing alignment |
| 2IN+ | Channel 2 non-inverting input | Second differential pair input; supports synchronous dual-channel signal processing |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | Internally compensated for unity-gain stability in both inverting and non-inverting configurations - eliminates need for external compensation networks |

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 |
|---|---|---|---|
| THS4032ID | 100 MHz bandwidth, lower noise (9 nV/√Hz), but higher supply current (12.5 mA/ch) and no null pins | Better suited for low-noise preamp stages; less ideal for video where differential gain/phase specs dominate | Select THS4032ID when bandwidth >70 MHz is required and video accuracy is secondary |
| OPA2691U | 1.5 GHz gain-bandwidth, current-feedback architecture, fixed gain ≥2 stability, no null pins | Requires different PCB layout (current-feedback topology); not drop-in for voltage-feedback designs | Choose OPA2691U only for ultra-high-speed (>200 MHz) applications where voltage-feedback limitations are reached |
Compared with THS4032ID and OPA2691U, the THS4052CD provides uniquely balanced video-grade linearity (0.01% DG/DP), dual-channel null adjustment, and guaranteed unity-gain stability - making it irreplaceable in broadcast infrastructure where signal fidelity and design simplicity are jointly prioritized.

FAQ
What is the maximum operating temperature range for the THS4052CD?
The THS4052CD is rated for operation from 0°C to 70°C (C-suffix), matching industrial commercial temperature requirements. This range is validated across all key parameters including bandwidth, distortion, and output drive - ensuring consistent performance in office, lab, and broadcast studio environments without derating.
Does the THS4052CD require external compensation for unity-gain stability?
No, the THS4052CD is internally compensated and stable at all closed-loop gains, including unity gain, in both inverting and non-inverting configurations. This eliminates the need for external compensation capacitors or resistor networks, simplifying layout and reducing bill-of-materials cost in video and instrumentation designs.
Can the THS4052CD drive a 75 Ω coaxial cable directly?
Yes, the THS4052CD delivers 100 mA per channel and is routinely used to drive 75 Ω video lines. For optimal return loss and stability, a series 20 Ω resistor is recommended at the output pin per TI application guidance - this isolates the amplifier from cable capacitance and prevents high-frequency ringing.
What is the purpose of the NULL pins on the THS4052CD?
The NULL pins (Pin 1 and Pin 8) on the THS4052CD provide access to the internal offset nulling network. Connecting a 10-kΩ potentiometer between them and grounding the wiper allows precise adjustment of input offset voltage to <1 mV - essential for DC-coupled video and precision instrumentation applications where baseline accuracy matters.
How does the THS4052CD compare to the THS4052CDGN variant?
The THS4052CDGN uses the same silicon die but is housed in an 8-pin MSOP PowerPAD™ package with superior thermal performance (θJA = 58.4°C/W vs. 167°C/W for SOIC). Both share identical electrical specifications, pinout, and functionality - the CDGN offers higher power dissipation headroom (2.14 W vs. 740 mW) for thermally constrained PCB layouts.
