Product details
Overview
THS4062CDGN from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier optimized for video, imaging, and communication signal conditioning. It delivers 180 MHz small-signal bandwidth (G = 1), 400 V/µs slew rate, and 40 ns settling time to 0.1%, driving ±3.5 V into 1 kΩ at ±5 V supply. Its role is precision analog signal amplification in professional video line drivers and high-fidelity ADC/DAC interface stages.
For engineers reviewing the THS4062CDGN datasheet, THS4062CDGN pinout, THS4062CDGN application, or THS4062CDGN equivalent, key selection criteria include its dual-channel layout, DGN package thermal performance, 75 MHz 0.1 dB flatness for composite video, low 0.02% differential gain error, and compatibility with ±4.5 V to ±16.5 V dual supplies or 9–33 V single supply.
Technical Context
The THS4062CDGN employs a dielectrically isolated complementary bipolar process enabling GHz fT transistors, delivering wide bandwidth and fast transient response without sacrificing stability. Its internal compensation ensures unity-gain stability in both inverting and noninverting configurations across full temperature range.
It features independent input common-mode ranges (±3.8 V at ±5 V supply), 70–110 dB CMRR, and channel-to-channel crosstalk of 65 dB at 1 MHz - critical for dual-channel integrity in synchronized analog paths such as RGB video or differential data acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - supports baseband video and broadband IF signal amplification without roll-off. |
| Slew rate | 400 V/µs at ±15 V - enables clean reproduction of fast edges in pulse and digital video waveforms. |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing requirements for high-speed data acquisition sampling clocks. |
| Differential gain error | 0.02% at NTSC 40 IRE, ±15 V - preserves color fidelity in broadcast-quality video transmission. |
| Output drive current | 115 mA typ per channel - drives 150 Ω video loads or multiple downstream inputs without external buffers. |
| Supply voltage range | ±4.5 V to ±16.5 V dual or 9–33 V single - accommodates legacy ±12 V, modern ±5 V, and industrial 24 V systems. |
| Total harmonic distortion | −72 dBc at 1 MHz - minimizes spectral contamination in RF sampling and communications receiver chains. |
Pinout & Package
The THS4062CDGN is housed in an 8-pin HVSSOP (PowerPAD™) package with exposed thermal pad on underside, requiring connection to PCB thermal plane for rated 2.14 W dissipation at TA ≤ 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | Offset null adjust (Channel 1) | Connect potentiometer wiper to VCC− for fine-tuning input offset voltage in precision DC-coupled applications. |
| 2 (1IN−) | Inverting input (Channel 1) | High-impedance node for feedback network attachment; trace length must be minimized to reduce parasitic capacitance. |
| 3 (1IN+) | Noninverting input (Channel 1) | DC-coupled or AC-coupled signal entry point; matched impedance critical for video differential pair routing. |
| 4 (VCC−) | Negative supply rail | Must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum close to pin to suppress high-frequency supply noise. |
| 5 (2IN+) | Noninverting input (Channel 2) | Independent input for second signal path; layout symmetry with Channel 1 reduces inter-channel coupling. |
| 6 (2IN−) | Inverting input (Channel 2) | Supports inverting gain configuration; same layout rules apply as Pin 2 for stability and bandwidth preservation. |
| 7 (2OUT) | Output (Channel 2) | Capable of sourcing/sinking 115 mA; series resistor (≥20 Ω) required when driving >10 pF capacitive loads. |
| 8 (VCC+) | Positive supply rail | Shared supply with Channel 1; separate decoupling required per rail to prevent crosstalk-induced distortion. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage feedback architecture | Enables predictable gain-bandwidth tradeoff and stable operation at G ≥ 1 without external compensation. |
| 75 MHz 0.1 dB flatness | Ensures amplitude consistency across NTSC/PAL luminance bandwidth, eliminating hue/saturation shift in analog video. |
| 0.02° differential phase error | Maintains precise timing alignment between chrominance components, preventing color bleeding in composite video. |
| PowerPAD™ thermal enhancement | Reduces junction-to-board thermal resistance by >50% vs standard MSOP, enabling sustained high-output operation at 70°C ambient. |
| 65 dB channel crosstalk | Preserves signal independence in dual-channel applications like stereo audio preamps or dual ADC drivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032CDGN | 100 MHz bandwidth, lower 14 nV/√Hz input voltage noise, 10 mA lower quiescent current. | Better suited for low-noise, low-power applications where 180 MHz bandwidth is unnecessary. | Select THS4032CDGN when optimizing for power efficiency and noise floor over speed; not drop-in for video bandwidth-critical designs. |
| LMH6622MMX | 150 MHz bandwidth, 350 V/µs slew rate, no PowerPAD, SO-8 package only. | Lacks thermal performance for sustained high-output drive; requires larger PCB area for equivalent heat dissipation. | Choose LMH6622MMX only if HVSSOP thermal constraints are absent and 180 MHz bandwidth margin is acceptable to sacrifice. |
Compared with THS4062CDGN, THS4032CDGN trades 80 MHz bandwidth for 30% lower power and improved noise, while LMH6622MMX offers comparable settling but lacks the DGN package's thermal advantage - making THS4062CDGN optimal for space-constrained, thermally demanding video and imaging systems.

FAQ
What is the maximum operating temperature range for the THS4062CDGN?
The THS4062CDGN is rated for operation from 0°C to 70°C (C-suffix). Its absolute maximum junction temperature is 150°C, and thermal design must ensure junction temperature remains within limits using the DGN package's PowerPAD™ connected to a PCB thermal plane. Derating begins above 25°C ambient, with 17.1 mW/°C reduction in power dissipation capacity.
Does the THS4062CDGN support single-supply operation?
Yes, the THS4062CDGN supports single-supply operation from 9 V to 33 V. Input common-mode range extends to within 1.2 V of rails (e.g., 3.8 V at ±5 V supply), and output swing reaches ±3.5 V into 1 kΩ with ±5 V supplies - enabling true single-rail use with proper level-shifting or AC-coupling in signal paths.
How does the THS4062CDGN achieve stability in unity-gain configurations?
The THS4062CDGN uses internal frequency compensation optimized for unity-gain stability in both inverting and noninverting modes. This allows direct G = 1 use without external compensation, though a 270 Ω feedback resistor is recommended for minimal ringing and optimal 40 ns settling time. Stability is maintained across full temperature and supply ranges.
Can the THS4062CDGN drive 75 Ω video loads directly?
Yes, the THS4062CDGN delivers 115 mA per channel and achieves ±3.2 V output swing into 150 Ω at ±5 V supply - sufficient for driving 75 Ω loads with appropriate gain-setting resistors. For optimal impedance matching and capacitive load isolation in 75 Ω systems, place a 75 Ω series resistor at the output per channel.
What evaluation module is available for the THS4062CDGN?
The THS4062EVM (literature number SLOP235) is the official Texas Instruments evaluation module for the THS4062CDGN. It features low-parasitic layout, configurable inverting/noninverting gain, and dedicated decoupling - enabling full validation of THS4062CDGN dynamic performance including 180 MHz bandwidth and 0.02% differential gain error.
