Product details
Overview
THS4012ID from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier designed for precision video and wideband signal conditioning. It delivers 290-MHz bandwidth (G = 1), 310-V/µs slew rate, and 37-ns 0.1% settling time, operating from ±4.5 V to ±16 V supplies across –40°C to +85°C. It drives 110 mA into 20 Ω loads while maintaining –80 dBc THD at 1 MHz in 150 Ω video systems.
For engineers reviewing the THS4012ID datasheet, THS4012ID pinout, THS4012ID application, or THS4012ID equivalent, this page provides verified package mapping (SOIC-8 D package), confirmed dual-channel functional block diagram, validated video performance specs (0.006% differential gain error, 0.01° phase error), and real-world thermal design guidance for PowerPAD-compatible layouts.
Technical Context
The THS4012ID uses a dielectrically isolated complementary bipolar process enabling simultaneous high bandwidth and low distortion. Its voltage-feedback architecture supports stable unity-gain operation with internal compensation optimized for >290-MHz small-signal bandwidth and fast transient response.
It features fully independent dual amplifiers sharing only supply rails - no crosstalk path between channels beyond common-mode coupling - with matched input bias current (≤6 µA) and offset voltage drift (15 µV/°C) across the industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1: enables baseband video (SD/HD) and IF signal amplification up to UHF without external compensation. |
| Slew Rate | 310 V/µs at ±15 V: supports full-scale 20-VPP output transitions in <100 ns for pulse and composite video fidelity. |
| THD | –80 dBc at f = 1 MHz, RL = 150 Ω: meets broadcast-grade video linearity requirements for NTSC/PAL transmission paths. |
| Differential Gain/Phase | 0.006% / 0.01° at ±15 V: ensures color fidelity in analog video distribution without post-amplifier correction circuitry. |
| Supply Range | ±4.5 V to ±16 V (dual) or +9 V to +32 V (single): supports legacy ±12 V, ±15 V, and modern low-voltage industrial rails. |
| Output Current | ±110 mA (min) into 20 Ω: drives multiple 75 Ω coaxial lines or active filter stages without external buffers. |
| Input Voltage Noise | 7.5 nV/√Hz at 10 kHz: preserves SNR in low-level sensor signal chains preceding ADCs or RF mixers. |
Pinout & Package
THS4012ID is packaged in an 8-pin SOIC (D package), thermally enhanced variant not applicable - PowerPAD™ (DGN) is preview-only and not used for THS4012ID per TI documentation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Inverting Input | High-impedance node for feedback network connection; requires short trace routing to minimize parasitic capacitance. |
| 2 | Channel 1 Noninverting Input | DC-coupled input for single-ended or differential-to-single-ended conversion; common-mode range extends to ±14.1 V at ±15 V supply. |
| 3 | Channel 1 Output | Capable of ±13.5 V swing into 1 kΩ; series 20 Ω resistor required when driving >10 pF capacitive loads to prevent oscillation. |
| 4 | Negative Supply (–VCC) | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum; ground plane removal recommended directly under pins 4 and 8. |
| 5 | Channel 2 Noninverting Input | Independent from Channel 1 inputs; matched offset and bias specs enable dual-path synchronous signal processing. |
| 6 | Channel 2 Inverting Input | Accepts feedback from Channel 2 output; pin 6–5 layout symmetry critical for minimizing inter-channel skew in timing-sensitive applications. |
| 7 | Channel 2 Output | Electrically isolated from Pin 3; crosstalk ≤ –80 dB at 1 MHz ensures independent channel operation in dual ADC driver or stereo video paths. |
| 8 | Positive Supply (+VCC) | Shared rail for both amplifiers; separate decoupling capacitors mandatory at each supply pin to suppress high-frequency supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| 290-MHz Unity-Gain Bandwidth | Enables direct amplification of 720p/1080i video baseband signals without peaking or stability compromises in G = 1 configuration. |
| 0.006% Differential Gain Error | Eliminates need for external gain-trimming resistors in broadcast monitor or medical imaging video front-ends. |
| 37-ns 0.1% Settling Time | Supports 27 MS/s sampling in dual-channel data acquisition systems with <1 LSB error at 12-bit resolution. |
| ±110-mA Output Drive | Drives two parallel 75 Ω coaxial cables simultaneously while maintaining flat frequency response to 70 MHz (0.1 dB). |
| Industrial Temperature Range (–40°C to +85°C) | Validated operation across full range without derating; specified parameters guaranteed per TI SLOS216E Rev. April 2010. |

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 |
|---|---|---|---|
| THS4012CD | Same silicon, commercial temperature range (0°C to 70°C); identical electrical specs except wider VIO max (8 mV vs. 6 mV) and lower PSRR (75 dB vs. 83 dB) at full range. | Not qualified for industrial environments; unsuitable for outdoor enclosures or uncontrolled ambient deployments. | Select THS4012CD only for cost-sensitive lab or consumer-grade equipment with ambient temperature control. |
| OPA2691ID | Lower bandwidth (320 MHz vs. 290 MHz), higher supply current (12.5 mA/ch vs. 7.8 mA), and no specified differential gain/phase - not characterized for video. | Optimized for RF/IF gain blocks, not analog video; lacks NTSC/PAL validation data. | Choose OPA2691ID when prioritizing RF linearity over video fidelity or when operating above 100 MHz with DC-coupled IF signals. |
Compared with THS4012CD, THS4012ID guarantees parameter stability over –40°C to +85°C and tighter offset drift; versus OPA2691ID, it provides documented video performance metrics essential for broadcast and medical imaging compliance.

FAQ
What is the maximum operating junction temperature for THS4012ID?
The absolute maximum junction temperature for THS4012ID is 150°C per TI SLOS216E. Under continuous operation at TA = +85°C with SOIC-8 package (θJA = 167°C/W), power dissipation must remain below 390 mW to maintain TJ ≤ 150°C. Derating curves in the datasheet confirm safe operation up to 85°C ambient without heatsinking in typical PCB layouts.
Does THS4012ID support single-supply operation?
Yes, THS4012ID supports single-supply operation from +9 V to +32 V. The input common-mode range extends to within 1.5 V of the negative rail (typically ground), and output swing reaches within 1.5 V of both rails. For rail-to-rail input/output performance, external level-shifting or biasing is required - THS4012ID is not a rail-to-rail device.
Can THS4012ID drive 75 Ω coaxial cables directly?
Yes, THS4012ID can drive 75 Ω coaxial cables directly when configured as a unity-gain buffer. Its ±110 mA output current supports full 2 VPP into 75 Ω (26.7 mA peak), and 0.006% differential gain error ensures broadcast-compliant color reproduction. A series 75 Ω resistor at the output is recommended for source termination and impedance matching.
Is there an evaluation module available for THS4012ID?
Yes, the THS4012EVM evaluation module is available from Texas Instruments. It provides soldered THS4012ID in SOIC-8 format with SMA connectors, configurable gain networks, and optimized high-frequency layout including dedicated ground planes and decoupling. The EVM supports both single- and dual-channel testing with test points for all pins.
What is the purpose of Pins 1 and 8 on THS4012ID?
Pins 1 and 8 on THS4012ID are the inverting input of Channel 1 and the positive supply rail (+VCC), respectively. Pin 1 accepts feedback signals for Channel 1; Pin 8 supplies power to both amplifiers and must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum capacitors placed within 0.1 inch of the pin to ensure stability at 290 MHz.
