Product details
Overview
THS4062IDGN from Texas Instruments is a dual-channel, high-speed voltage-feedback operational amplifier optimized for professional video, imaging, and communication signal conditioning. It delivers 180 MHz small-signal bandwidth (G = 1), 400 V/µs slew rate, 40 ns settling time (0.1%), ±11.5 V output swing into 250 Ω, and 0.02% differential gain error - enabling precision analog signal amplification in broadcast-grade video line drivers and high-fidelity ADC/DAC buffers.
For engineers reviewing the THS4062IDGN datasheet, THS4062IDGN pinout, THS4062IDGN application, or THS4062IDGN equivalent, key selection criteria include its dual-channel MSOP-8 PowerPAD™ package, wide ±4.5 V to ±15 V dual-supply operation, stability at all gains, and verified 75 MHz 0.1 dB flatness for composite video distribution.
Technical Context
The THS4062IDGN employs a dielectrically isolated complementary bipolar process with GHz fT transistors, enabling voltage-feedback architecture with unity-gain stability across inverting and noninverting configurations. Its internal compensation balances wide bandwidth and phase margin, requiring only 270 Ω feedback for optimal 0.1% settling in G = +1 applications.
Designed for low-distortion analog signal paths, it integrates null pins for offset trimming and supports capacitive load driving via series output isolation (≥20 Ω). Channel-to-channel crosstalk is −65 dB at 1 MHz, confirming independent dual-amplifier operation without inter-channel interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (−3 dB) | 180 MHz at G = 1, ±15 V - supports full HD video baseband and fast pulse amplification without attenuation |
| Slew rate | 400 V/µs at ±15 V - enables clean reproduction of >100 MHz square waves with minimal edge distortion |
| Settling time (0.1%) | 40 ns for 5-V step - meets timing-critical sampling requirements in high-speed data acquisition systems |
| Differential gain error | 0.02% at NTSC 40 IRE, ±15 V - preserves color fidelity in broadcast video transmission |
| Output drive | 115 mA per channel (±15 V, RL = 20 Ω) - drives multiple 75 Ω video lines or heavy capacitive loads |
| THD | −72 dBc at 1 MHz - ensures low-noise signal integrity in audio and instrumentation front-ends |
| Supply range | ±4.5 V to ±15 V dual supply - compatible with legacy ±5 V and industrial ±12 V rails |
Pinout & Package
The THS4062IDGN is housed in an 8-pin HVSSOP (DGN) package with exposed thermal pad (PowerPAD™), requiring connection to PCB ground plane for thermal management and optimal power dissipation (2.14 W at TA ≤ 25°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null (Channel 1) | Offset null adjustment terminal; connect potentiometer wiper to VCC− for fine-tuning input offset |
| 2 | Inverting input (Ch1) | High-impedance node for feedback network connection; requires short trace to minimize parasitic capacitance |
| 3 | Non-inverting input (Ch1) | High-impedance reference input; must be decoupled with low-inductance 0.1 µF capacitor near pin |
| 4 | VCC− | Negative supply rail; requires dedicated 6.8 µF tantalum + 0.1 µF ceramic decoupling at pin |
| 5 | VCC+ | Positive supply rail; identical decoupling required as VCC− for PSRR optimization |
| 6 | Output (Ch1) | Capable of ±11.5 V swing into 250 Ω; add ≥20 Ω series resistor when driving >10 pF loads |
| 7 | Inverting input (Ch2) | Independent second channel input; layout symmetry critical to maintain −65 dB crosstalk |
| 8 | Null (Channel 2) | Separate offset null for Channel 2; not internally connected to Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable | Operates without external compensation in both inverting and noninverting configurations at any gain |
| 75 MHz 0.1 dB flatness | Maintains amplitude accuracy across entire NTSC/PAL baseband spectrum without equalization |
| Low differential phase error | 0.02° at ±15 V enables sub-degree timing alignment between luminance and chrominance signals |
| PowerPAD™ thermal enhancement | Enables 2.14 W power dissipation in MSOP-8 footprint - 2.9× higher than standard SOIC-8 |
| Wide supply range | Supports ±4.5 V to ±15 V operation, allowing reuse across 5 V, ±12 V, and ±15 V system designs |

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 |
|---|---|---|---|
| THS4032IDGN | 100 MHz bandwidth, lower 12 nV/√Hz noise, 200 V/µs slew rate - optimized for low-noise over speed | Better suited for precision sensor interfaces where SNR > bandwidth; insufficient for 75 MHz video flatness | Select THS4032IDGN when noise dominates design constraints and 100 MHz BW suffices |
| LMH6622MMX | 150 MHz bandwidth, 350 V/µs slew rate, no null pins, SOIC-8 only - lacks PowerPAD™ thermal capability | Acceptable for moderate-power video buffering but cannot sustain 115 mA continuous drive like THS4062IDGN | Choose LMH6622MMX for cost-sensitive, lower-power dual-op-amp needs without thermal pad requirement |
Compared with THS4032IDGN and LMH6622MMX, the THS4062IDGN uniquely combines 180 MHz bandwidth, 75 MHz 0.1 dB flatness, and PowerPAD™ thermal performance in MSOP-8 - making it the only option qualified for sustained dual-channel broadcast video line driving at ±15 V.

FAQ
What is the operating temperature range for the THS4062IDGN?
The THS4062IDGN is rated for industrial operation from −40°C to +85°C, as indicated by the "I" suffix in the part number. This range is validated across all electrical specifications including bandwidth, slew rate, and output drive capability, ensuring reliable performance in harsh environments such as broadcast enclosures and factory-floor test systems.
Does the THS4062IDGN require external compensation for unity-gain stability?
No, the THS4062IDGN is internally compensated and unity-gain stable in both inverting and noninverting configurations without external components. For optimal 0.1% settling time in G = +1 circuits, TI recommends using a 270 Ω feedback resistor - a design choice that optimizes phase margin without altering inherent stability.
How does the PowerPAD™ thermal pad on the THS4062IDGN improve thermal performance?
The exposed thermal pad on the THS4062IDGN's DGN package must be soldered to a PCB ground plane to achieve its rated 2.14 W power dissipation at 25°C ambient. Without this connection, junction temperature rises significantly, risking thermal shutdown or accelerated parametric drift - especially under sustained 115 mA output current conditions.
Can the THS4062IDGN drive 75 Ω video loads directly?
Yes, the THS4062IDGN can drive 75 Ω loads directly when configured as a line driver with G = 2, delivering ±3.2 V swing and maintaining 0.02% differential gain. For optimal impedance matching and capacitive load immunity, TI recommends adding a 75 Ω series resistor at the output - which simultaneously isolates stray capacitance and establishes proper source termination.
What is the purpose of Pins 1 and 8 on the THS4062IDGN?
Pins 1 and 8 are independent offset null terminals for Channel 1 and Channel 2 respectively. Each accepts a potentiometer (e.g., 10 kΩ) with wiper tied to VCC−, enabling fine adjustment of input offset voltage down to sub-millivolt levels - critical for DC-coupled video and precision instrumentation applications where baseline shift degrades accuracy.
