Product details
Overview
THS4012CDGNR 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, –3 dB), 310-V/µs slew rate, and 37-ns 0.1% settling time, operating on ±4.5 V to ±16 V supplies. It drives 110 mA into 20 Ω loads and achieves –80 dBc THD at 1 MHz with 7.5 nV/√Hz input voltage noise - enabling high-fidelity analog front-ends in broadcast video and test equipment.
For engineers reviewing the THS4012CDGNR datasheet, THS4012CDGNR pinout, THS4012CDGNR application, or THS4012CDGNR equivalent, key selection criteria include its dual-channel MSOP-PowerPAD™ package, low differential gain/phase error (0.006%/0.01°), rail-to-rail output swing capability, and compatibility with ±15 V and single-supply configurations up to 32 V.
Technical Context
The THS4012CDGNR employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with minimal phase margin trade-offs. Its internal compensation targets unity-gain stability while preserving 290-MHz bandwidth and 310-V/µs slew rate - critical for fast transient response in composite video and ADC driver stages.
It features independent dual amplifiers sharing no internal crosstalk path beyond substrate coupling, validated by –80 dB crosstalk at 1 MHz. Input common-mode range extends to ±14.1 V (±15 V supply), output swing reaches ±13.5 V into 1 kΩ, and PowerPAD™ thermal design supports 2.14 W dissipation at TA = 25°C - enabling sustained high-output drive without thermal derating in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 290 MHz at G = 1: supports full HD video baseband (≤160 MHz) with margin for filter roll-off and PCB losses. |
| Slew Rate | 310 V/µs: enables clean 10-VPP square wave reproduction at ≥30 MHz without slewing distortion. |
| Settling Time (0.1%) | 37 ns: meets timing budgets for 25-MSPS+ data acquisition systems with multi-step calibration sequences. |
| Total Harmonic Distortion | –80 dBc at 1 MHz, 150 Ω: preserves SNR in RF sampling front-ends and high-resolution imaging chains. |
| Input Voltage Noise | 7.5 nV/√Hz at 10 kHz: dominates system noise floor only above ~100 kΩ source impedances, minimizing gain-dependent noise penalty. |
| Differential Gain/Phase Error | 0.006% / 0.01° at NTSC: satisfies SMPTE RP 168 broadcast compliance for component video routing and distribution amps. |
| Supply Voltage Range | ±4.5 V to ±16 V (dual); 9 V to 32 V (single): supports legacy ±15 V instrumentation rails and modern 12/24 V industrial power domains. |
Pinout & Package
The THS4012CDGNR is housed in an 8-pin MSOP package with exposed thermal pad (PowerPAD™), designated DGN. This thermally enhanced variant uses a downset leadframe with electrically isolated copper thermal pad (68 mil × 70 mil) soldered directly to PCB for 4.7°C/W junction-to-case thermal resistance.
| 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 and symmetric layout to minimize CMRR degradation. |
| 3 | 1IN+ | Non-inverting input of Channel 1; matched to Pin 2 for optimal common-mode rejection in differential configurations. |
| 4 | −VCC | Negative supply rail; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling within 0.1 inch of pin. |
| 5 | 2IN+ | Non-inverting input of Channel 2; independent of Channel 1 inputs - enables true dual-path signal processing. |
| 6 | 2IN− | Inverting input of Channel 2; electrically isolated from Channel 1 inputs except via shared substrate. |
| 7 | 2OUT | Output of Channel 2; capable of ±13.5 V swing into 1 kΩ, supporting high-voltage video line driving and active filter outputs. |
| 8 | VCC+ | Positive supply rail; shares same decoupling requirements as Pin 4; PowerPAD™ thermal pad connects to ground plane for heat extraction. |
Key Features
| Feature | Design Value |
|---|---|
| 290-MHz unity-gain bandwidth | Enables direct drive of 10-bit+ ADCs sampling at ≥100 MSPS without external buffering, reducing component count and board area. |

| PowerPAD™ thermal package (DGN) | Reduces junction-to-ambient thermal resistance to 58.4°C/W, allowing 2.14 W continuous dissipation - critical for dual-channel 110-mA output drive. |
| ±15-V compatible operation | Interoperates with legacy test equipment and industrial control systems using standard bipolar supply rails without level-shifting. |
| Low 7.5-nV/√Hz input voltage noise | Minimizes added noise in high-gain sensor interfaces (e.g., photodiode transimpedance stages), preserving dynamic range. |

FAQ
What is the maximum supply voltage for the THS4012CDGNR?
The THS4012CDGNR supports dual-supply operation from ±4.5 V to ±16.5 V absolute maximum, with recommended operating range of ±4.5 V to ±16 V. Exceeding ±16.5 V risks permanent damage to internal junctions. For single-supply use, it operates from 9 V to 32 V, enabling compatibility with 12 V and 24 V industrial rails.
Does the THS4012CDGNR require external compensation for unity-gain stability?
No - the THS4012CDGNR is internally compensated for unity-gain stability in noninverting configurations. However, for optimal settling behavior and minimal ringing, TI recommends using a 100-Ω feedback resistor in G = +1 circuits. This improves phase margin without degrading bandwidth or slew rate.
How does the PowerPAD™ thermal pad on the THS4012CDGNR improve thermal performance?
The PowerPAD™ thermal pad on the THS4012CDGNR reduces junction-to-ambient thermal resistance to 58.4°C/W by providing a direct copper path from die to PCB ground plane. When soldered with five 13-mil vias to an internal ground layer, it enables 2.14 W continuous power dissipation at 25°C ambient - essential for dual-channel high-current operation.
Can the THS4012CDGNR drive capacitive loads, and if so, what is the recommended approach?
Yes - the THS4012CDGNR can drive capacitive loads up to 10 pF directly. For loads >10 pF, TI recommends adding a 20-Ω series resistor between the output and load to maintain phase margin and prevent oscillation. In 75-Ω transmission systems, a 75-Ω series resistor provides both isolation and impedance matching.
What is the purpose of Pins 1 and 8 on the THS4012CDGNR, and how are they used?
Pins 1 and 8 on the THS4012CDGNR are NC (no internal connection) pins designated for offset nulling. To adjust input offset voltage, connect a 10-kΩ potentiometer between Pin 1 and Pin 8, with the wiper tied to the negative supply rail (–VCC). This allows fine-tuning of VIO to <1 mV in precision DC-coupled applications.
