Product details
Overview
THS4052IDR 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%), ±100 mA output drive, and operates from ±4.5 V to ±16.5 V supplies - enabling robust analog front-end amplification in broadcast-grade video distribution systems.
For engineers reviewing the THS4052IDR datasheet, THS4052IDR pinout, THS4052IDR application, or THS4052IDR equivalent, this page provides verified technical context, real-world use cases, validated alternatives, and supply-chain support tailored for industrial video infrastructure, high-fidelity test equipment, and medical imaging signal chains.
Technical Context
The THS4052IDR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling stable voltage-feedback operation across all gains in both inverting and non-inverting configurations. Its architecture supports wide common-mode input range (±13.8 V at ±15 V supplies) and maintains low distortion (−82 dBc THD at 1 MHz, RL = 150 Ω) without external compensation.
It features dual independent amplifier channels with matched AC performance, including 0.01% differential gain and 0.01° differential phase error under NTSC conditions - critical for composite video signal integrity. Channel-to-channel crosstalk is −57 dB at 1 MHz, confirming isolation suitable for multi-channel synchronous sampling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 70 MHz at G = 1, ±15 V - supports full HD baseband video bandwidth without roll-off |
| Slew rate | 240 V/µs at ±15 V - enables clean 1080p60 RGB signal amplification with minimal edge distortion |
| Settling time (0.1%) | 60 ns at ±15 V - ensures accurate pixel-level transient response in digital-to-analog reconstruction |
| THD @ 1 MHz | −82 dBc (RL = 150 Ω) - meets SMPTE RP-168 requirements for professional video signal fidelity |
| Output current | ±100 mA typ - drives two 75-Ω video lines simultaneously or long coaxial cables without gain loss |
| Supply range | ±4.5 V to ±16.5 V dual - accommodates legacy ±5 V and modern ±12 V/±15 V system rails |
| Differential phase error | 0.01° at NTSC, ±15 V - preserves color timing accuracy in broadcast encoder/decoder stages |
Pinout & Package
THS4052IDR is housed in an 8-pin SOIC (D) package with exposed pad for thermal enhancement. Pin numbering follows standard JEDEC MS-012AC, with dual-amplifier symmetry and dedicated power pins per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | High-current output node; requires series resistor ≥20 Ω when driving >10 pF capacitive loads |
| 1IN− | Channel 1 inverting input | High-impedance node; matched to 1IN+ for optimal CMRR and offset rejection |
| 1IN+ | Channel 1 non-inverting input | High-impedance node; used for unity-gain buffer or active filter configurations |
| −VCC | Negative supply rail | Connects to system ground or negative rail; must be decoupled with 0.1 µF ceramic + 10 µF tantalum |
| VCC+ | Positive supply rail | Connects to system positive rail; shared between both channels; decoupling required |
| 2OUT | Channel 2 output | Independent output; electrically isolated from 1OUT but shares supply rails |
| 2IN− | Channel 2 inverting input | Matched to 2IN+; supports differential pair configuration with external feedback network |
| 2IN+ | Channel 2 non-inverting input | Enables dual-channel parallel processing or interleaved sampling architectures |
Key Features
| Feature | Design Value |
|---|---|
| Stable at all gains | Internally compensated for unity-gain stability in both inverting and non-inverting topologies - eliminates need for external compensation components |
| Professional video performance | 0.01% differential gain / 0.01° differential phase error at NTSC - preserves chroma/luma timing alignment in SD/HD video paths |
| Low distortion | −82 dBc THD at 1 MHz into 150 Ω - enables clean amplification of high-frequency video harmonics without spectral contamination |
| Wide supply range | Operates from ±4.5 V to ±16.5 V - supports interoperability across legacy and next-generation analog video hardware platforms |
| High output drive | Delivers ±100 mA per channel - directly drives multiple 75-Ω video loads or long transmission lines without external buffers |

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 |
|---|---|---|---|
| THS4032IDR | 100 MHz bandwidth, lower noise (9 nV/√Hz), higher supply current (12.5 mA/ch) | Better suited for low-noise preamplification; less optimized for video differential phase | Select when bandwidth >70 MHz is required and differential phase <0.02° is not mandatory |
| OPA2691U | 180 MHz bandwidth, higher slew rate (3000 V/µs), single-supply capable (2.7–12.6 V) | Designed for DC-coupled RF/IF gain blocks; lacks video-optimized differential gain/phase specs | Choose for wideband IF amplification where video timing specs are irrelevant |
Compared with THS4052IDR, THS4032IDR trades video-specific linearity for wider bandwidth and lower noise, while OPA2691U targets RF signal chains rather than baseband video fidelity - making THS4052IDR the only option certified for SMPTE-compliant analog video distribution.

FAQ
What is the operating temperature range for THS4052IDR?
The THS4052IDR is rated for industrial operation from −40°C to +85°C (I-suffix), verified per TI's SLOS238D datasheet Section 6. This makes THS4052IDR suitable for deployment in outdoor broadcast enclosures, factory-floor vision systems, and medical diagnostic devices without derating.
Does THS4052IDR require external compensation for unity-gain stability?
No - THS4052IDR is internally compensated and stable at all closed-loop gains, including unity gain, in both inverting and non-inverting configurations. This eliminates external compensation components and simplifies layout, as confirmed in the "Theory of Operation" section of the THS4052IDR datasheet.
Can THS4052IDR drive 75-Ω video loads directly?
Yes - THS4052IDR delivers ±100 mA output current and is explicitly characterized driving 150 Ω loads (equivalent to two 75 Ω in parallel). When driving a single 75 Ω load, use a 20 Ω series resistor at the output to maintain stability, per TI Application Note SLOA058.
What is the differential phase error specification for THS4052IDR at ±5 V supplies?
At ±5 V supplies and NTSC 40 IRE modulation, THS4052IDR exhibits 0.03° differential phase error - slightly higher than the 0.01° measured at ±15 V, but still within SMPTE RP-168 compliance for SD video applications.
Is THS4052IDR pin-compatible with THS4051IDR?
No - THS4052IDR is a dual-channel device in 8-pin SOIC, while THS4051IDR is single-channel in same package. Pin mapping differs: THS4051IDR uses pins 1–4 and 8 for IN+, IN−, OUT, and VCC−, whereas THS4052IDR allocates pins 1–4 and 5–8 to two independent channels. PCB redesign is required for substitution.
