Product details
Overview
THS4012CDGNG4 from Texas Instruments is a dual-channel, voltage-feedback high-speed operational amplifier optimized 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 on ±5-V to ±15-V supplies. It drives 110 mA into 150 Ω loads and achieves –80 dBc THD at 1 MHz in broadcast-grade NTSC video systems.
For engineers reviewing the THS4012CDGNG4 datasheet, THS4012CDGNG4 pinout, THS4012CDGNG4 application, or THS4012CDGNG4 equivalent, key selection considerations include its dual-channel layout in MSOP-PowerPAD™ package, low 7.5-nV/√Hz input voltage noise, 0.006% differential gain error, and thermal performance enabled by the exposed thermal pad - all critical for high-fidelity analog front-ends and high-speed data acquisition.
Technical Context
The THS4012CDGNG4 employs a dielectrically isolated complementary bipolar process enabling simultaneous high bandwidth, fast settling, and low distortion. Its voltage-feedback architecture supports stable unity-gain operation with internal compensation tuned for minimal phase margin trade-off in noninverting configurations.
It features fully independent dual amplifiers sharing only supply rails, with no crosstalk specification exceeding –80 dB at 1 MHz. Input stage design enables ±13 V common-mode range (±15 V supply) and 82 dB CMRR, while output stage delivers rail-to-rail-capable swing of ±13.5 V into 1 kΩ and ±13 V into 250 Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1 - supports full HD video baseband and >100 MSPS ADC driver applications without gain peaking. |
| Slew Rate | 310 V/µs - enables clean reproduction of 20-VPP signals up to ~5 MHz without slewing distortion. |
| Settling Time (0.1%) | 37 ns - meets timing budgets for 25-MSPS+ sampling systems with <1 LSB error in 14-bit systems. |
| Total Harmonic Distortion | –80 dBc at f = 1 MHz, RL = 150 Ω - ensures <0.01% nonlinear artifacts in composite video and instrumentation signal chains. |
| Differential Gain/Phase Error | 0.006% / 0.01° at NTSC, G = 2 - preserves color fidelity in professional video routing and broadcast equipment. |
| Input Voltage Noise | 7.5 nV/√Hz - maintains SNR integrity when amplifying µV-level sensor outputs or low-level IF signals. |
| Supply Voltage Range | ±4.5 V to ±16 V - supports legacy ±5 V, ±12 V, and modern ±15 V industrial and test equipment rails. |
Pinout & Package
THS4012CDGNG4 is housed in an 8-pin MSOP package with PowerPAD™ thermal enhancement (DGN). The exposed copper thermal pad on the underside improves junction-to-board thermal resistance to 58.4°C/W, enabling 2.14 W power dissipation at TA = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC (No internal connection) | Unused pin; must be left floating or tied to ground per layout best practice to minimize parasitic coupling. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance node requiring guarded trace routing to limit noise pickup. |
| 3 | 1IN+ | Noninverting input of Channel 1 - matched to Pin 2 for optimal CMRR; sensitive to PCB trace asymmetry. |
| 4 | −VCC | Negative supply rail - requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling within 0.1 inch. |
| 5 | 2IN+ | Noninverting input of Channel 2 - electrically isolated from Channel 1 inputs; shares no internal substrate path. |
| 6 | 2IN− | Inverting input of Channel 2 - independent bias network; differential pair offset uncorrelated with Channel 1. |
| 7 | 2OUT | Output of Channel 2 - capable of sourcing/sinking 110 mA; series 20 Ω resistor required for >10 pF capacitive loads. |
| 8 | 1OUT | Output of Channel 1 - identical drive capability to Pin 7; layout symmetry recommended to minimize inter-channel crosstalk. |

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, SOIC-8 package (no PowerPAD™); θJA = 167°C/W; max power dissipation 740 mW at TA = 25°C. | Limited to lower-output-current applications (<60 mA continuous) or forced-air-cooled environments. | Select when board space permits SOIC and thermal load is ≤500 mW; avoid for sustained 110-mA output. |
| LMH6702MA/NOPB | Single-channel, 1.8-GHz GBW, 3000-V/µs slew; higher noise (9.5 nV/√Hz); no differential gain spec. | Better for RF IF amplification but unsuitable for broadcast video due to lack of video-specific distortion specs. | Choose for >500-MHz small-signal gain stages where video fidelity is not required. |
Compared with THS4012CDGNG4, THS4012CD offers identical electrical performance but reduced thermal headroom, while LMH6702MA/NOPB trades video-optimized linearity for raw speed - making THS4012CDGNG4 the only option meeting both 290-MHz bandwidth and SMPTE-compliant video error specs in a thermally robust MSOP package.

FAQ
What is the maximum safe operating temperature for THS4012CDGNG4?
The THS4012CDGNG4 has a maximum junction temperature (TJ) rating of 150°C. With its DGN package thermal resistance (θJA) of 58.4°C/W, it can sustain continuous operation at ambient temperatures up to 70°C while delivering full 110-mA output current - provided the PCB includes five 13-mil vias under the thermal pad connected to an internal ground plane.
Does THS4012CDGNG4 require external offset nulling in precision applications?
The THS4012CDGNG4 has a typical input offset voltage of 1 mV (max 6 mV), which is low for a high-speed op-amp. Offset nulling is optional and implemented via a potentiometer between Pins 1 and 8, with wiper tied to −VCC. Most video and data acquisition applications operate within spec without nulling, but it remains available for sub-mV DC accuracy requirements.
Can THS4012CDGNG4 drive 75-Ω transmission lines directly?
Yes - THS4012CDGNG4 can drive 75-Ω lines directly when configured with a 75-Ω series resistor at the output (Pin 7 or Pin 8), as recommended in TI's Application Information section. This isolates capacitive loading, prevents high-frequency ringing, and provides source-end impedance matching for minimal signal reflection in video routing applications.
How does the PowerPAD™ feature improve THS4012CDGNG4 thermal performance?
The PowerPAD™ on THS4012CDGNG4 reduces thermal resistance from junction to board by providing a direct copper path to the PCB. With proper layout (five 13-mil vias under the pad connected solidly to ground), θJA drops to 58.4°C/W - enabling 2.14 W power dissipation at TA = 25°C, versus just 740 mW for the SOIC-packaged THS4012CD.
Is THS4012CDGNG4 suitable for single-supply operation?
Yes - THS4012CDGNG4 supports single-supply operation from 9 V to 32 V. When used this way, the input common-mode range extends from 3.8 V to 4.3 V below VCC (at ±5 V equiv), and output swing reaches within 1.5 V of each rail. For rail-to-rail input/output, external level-shifting or biasing is required, as the device is not rail-to-rail compatible.
